“…In recent years, the searches for low-cost agricultural by-products have been widely studied for metal ion removal from water and wastewater. These include Citrus reticulata [4], maize cob [5], Tectona grandis leaves [6], neem biomass [7], Eucalyptus camaldulensis leaves [8], rice straw [9], rice husk [10], Eucalyptus bark, mango bark and pine apple fruit peel [11], Moringa oleifera bark [12], hazelnut, almond and walnut shells [13], Pinus gerardiana leaves [14], Cynodon dactylon, Psidium guajava, Azadirachta indica, Cassia tora and Cassia angustifolia leaves [15], coconut leaves [16], Ashoka leaf [17], Ceratonia siliqua bark [18] and Eriobotrya japonica bark [19]. This paper presents the study of biosorption characteristics of Sophora japonica pods powder (Sjp) for the removal of Cu(II), Ni(II), Zn(II) and Pb(II) ions from aqueous solution in batch process.…”

Background Biosorption of Cu (II), Ni(II), Zn(II) and Pb(II) ions from aqueous solutions onto Sophora japonica pods powder has been studied using batch adsorption technique. The biosorption studies were determined as a function of pH, contact time, initial metal ion concentration, biosorbent dosage and temperature. Results The kinetic study showed that the biosorption of the Cu(II), Ni(II), Zn(II) and Pb(II) ions followed pseudosecond-order kinetic model. Experimental data obtained were analyzed with Langmuir, Freundlich, Dubinin-Radushkevich and Temkin isotherm models and in each case the Langmuir model appears to have better regression coefficients. Thermodynamic parameters: DG°, DH°and DS°were calculated indicating that the biosorption of Cu(II), Ni(II), Zn(II) and Pb(II) ions is spontaneous and endothermic process. Conclusions The results of the study showed that Sophora japonica pods powder can be efficiently used as a low-cost alternative for the removal of Cu(II), Ni(II), Zn(II) and Pb(II) ions from aqueous solutions.

“…Heavy metals are non-biodegradable and have tendency to get accumulated inside the human body via incorporation through food chain [3][4][5][6][7]. Major industrial operations unit like metallurgy, steel production, paint and pigment industry, copper smelting unit, acid mine drainage, electroplating, and metal finishing significantly contribute to heavy metal pollution in natural water streams [8][9][10][11][12].…”

“…The biosorption of metal ion across liquid phase is a better option compared to other metal ion remediation methodologies [16,37]. Biosorption has several noteworthy advantages over traditional heavy metal remediation technologies which are as follows: (a) biosorption of heavy metals across liquid/aqueous phase is robust method with respect to metal ion specificity and inexpensive in terms of cost input required for biosorption system development, (b) the biosorption method can work with high fidelity in very dilute metal ion solution, (c) there is no requirement of additional nutrients for growth of living biomasses implemented as biosorbent coupled with no generation of secondary chemical sludge hence sorting out the problem of disposal of sludge loaded with heavy metal, and (d) the regeneration of biosorbents is very easy resulting in repeated usage of biosorbent [7,38]. Various living and non-living adsorbents have been implemented for metal ion removal across liquid phase viz.…”

“…Various living and non-living adsorbents have been implemented for metal ion removal across liquid phase viz. eucalyptus bark [7], mango bark saw dust [7], pineapple fruit peel powder [7], algae [39], bacteria [40], and fungi [41]. The biosorption systems used to date were cost effective and robust in terms changing/varying environmental conditions but still there are many more possibilities of exploring biosorption nature of various biomasses to make biosorption a more versatile process of heavy metal ion remediation.…”

Bioremediation of Zn(II) by biosorption across aqueous phase on to surface of eucalyptus leaf powder has been investigated in present research work. The adsorptive potential of eucalyptus leaf powder was evaluated as function of pH, temperature, contact time, agitation rate and particle size. Maximum metal ion uptake and percentage removal capacity of eucalyptus leaf powder were 23.5 mg g À1 and 94%, respectively, at optimized pH 5, 20 AE 18C, contact time 6 h, particle size 0.5 mm and agitation rate 200 rpm. The biomass surface analysis revealed the fact that the biomass surface was heterogeneous and porous in nature. The functional groups like amine, amide, carboxyl, hydroxyl, and methyl groups, significantly important for metal ion binding were present on biomass surface in tremendous amount. Additionally, the Fourier transformation IR spectrum analysis of acid and base activated eucalyptus leaf biomass ruled out all the possibilities of the presence of surface functional groups mentioned above. The reaction rate was studied by applying two rate limiting models pseudo first and pseudo second order. Pseudo second order model was found to be more suitable (R 2 ¼ 0.998) in comparison to pseudo first order (R 2 ¼ 0.724). Adsorption equilibrium of batch stirred reaction data fitting shows the dominance of Langmuir isotherm (R 2 ¼ 0.99) against Freundlich isotherm (R 2 ¼ 0.887) model with equipartitional involvement of both film and intra particle diffusion as rate limiting steps at differential status of contact time.Keywords: Bioremediation; Intra particle diffusion; Langmuir isotherm; Pseudo second order reaction; Zn(II) ion IntroductionThe rapid and tremendous industrial development during last decade has increased the heavy metal pollution in environment [1,2]. Heavy metals are non-biodegradable and have tendency to get accumulated inside the human body via incorporation through food chain [3][4][5][6][7]. Major industrial operations unit like metallurgy, steel production, paint and pigment industry, copper smelting unit, acid mine drainage, electroplating, and metal finishing significantly contribute to heavy metal pollution in natural water streams [8][9][10][11][12]. Various remedial technologies/unit operations viz. osmosis, electro coagulation and flocculation, reverse osmosis, solvent extraction, hydroxide precipitation, and membrane separation have been adopted to remove heavy metals across liquid phase [13,14]. In general, all these above mentioned technologies are expensive, lead to generation of secondary chemical sludge containing heavy metals, making the disposal of sludge questionable, and ineffective in removing heavy metals including Zn(II), Cd(II), Pb(II), Cu(II), and Cr(III) at low concentration levels ranging between 1 and 100 mg L À1 [10,[15][16][17][18][19]. Zinc is one of the elements of heavy metal series. Though zinc is an essential element of life but its exposure beyond permissible limit, defined by United States Environmental Protection Agency, World Health Organization, Canadian Wate...

The aim of this study was to obtain new films based on collagen-chitosan with and without silver for biomedical applications. Membranes with a thin transparent elastic structure were obtained and after immersion in silver nitrate new membranes with silver have been elaborated and their physicochemical properties were assessed using infrared spectroscopy as well as contact angle determinations, and sorption properties. The water absorption has permitted the evaluation of the diffusion coefficient for modified collagen membranes and the values were comparable with diffusion coefficient specific for human cornea. Adsorption and desorption studies of silver ions were investigated based on the concentration of the silver solution. This concentration was determined by an inductively coupled plasma spectrometer. Antimicrobial investigations performed on Gram-negative Escherichia coli and Gram-positive Staphylococcus aureus bacteria and hemolytic properties assays have been evaluated measuring optical density. The enhancement of antibacterial activity of membranes with silver content was emphasized.
