“…Short adsorption times are favored for minimum energy consumption and the product is therefore efficient for Cs + removal when its very satisfactory short adsorption time is considered. The kinetic results obtained from batch experiments were analyzed using different kinetics models such as the Lagergren pseudo-first-order [43,44] and pseudo-second-order models [45][46][47][48][49][50][51][52][53][54][55][56][57]. The Lagergren pseudo-first-order model is given by:…”

Abstract. Tobermorite was synthesized successfully from the ash, which was produced and detoxified from asbesto-containing disaster waste in great east Japan earth quake, by alkali hydrothermal treatment. Tobermorite synthesis was examined as a function of reaction temperature and NaOH concentration. The formation of tobermorite was identified in the product treated with 1-4 M NaOH solution at 130 and 180 o C, while no product phases was identified at 80 o C. With increasing reaction temperature, intensity of tobermorite phase in the product and Cs + removal ability of the product increase. The product, which was treated with 4 M NaOH at 180 o C for 20 h, revealed the high selective uptake for Cs + in saline water. The Cs + uptake of the product was extrapolated using Langmuir and Freundlich isotherm models, experimental data are found to fit Langmuir than Freundlich, and the calculated uptake amount was 0.51 mmol/g. The kinetics for Cs + uptake was tested for pseudo-second order reactions, and the rate constants of uptake were calculated. With increasing temperature of aqueous solution, the kinetics of uptake is almost same and the uptake amount of Cs + decreases. The product is expected to be used for Cs + removal from wastewater.

The present study describes the potential of mixed fungal isolates, i.e. Aspergillus niger, Penicillium chrysogenum and Rhizopus oryzae for the removal of zinc(II) and copper(II) from aquatic environments. Capacity of mixed fungal biomass to adsorb Zn(II) and Cu(II) were studied in batch sorption experiments as bioremediators. Optimal conditions from contact time, pH, initial metal ion concentration and temperature for remediation of Zn(II) and Cu(II) were studied. Typically, the uptake of Zn(II) and Cu(II) rises with increasing pH up to 4.0. Optimal metal concentration was 150 mg/l when the maximum removal of copper and zinc was 69.5% and 30.3% respectively, was observed at initial metal concentration. Maximum uptake for metals was achieved after 15 min. The maximum biosorption for copper and zinc by selected fungi was achieved at 7.0 g of biosorbent. IR spectrum of three fungal species showed the presence of C=O groups, amine and amide N-H functional stretch.Keywords: Biosorption, copper, electroplating effluent, fungal isolates, zinc.WASTEWATER during electroplating activities involves poisonous heavy metals like chromium, mercury, zinc, nickel, cadmium, phosphorus and copper which build up in the food chain and cause different pathological states 1,2 . In recent years, association of different microbes has been used for wastewater treatment as bioremediators, as it was considered to have greater capability over pure and single isolates. The axenic cultures were devised to be mineralized rapidly and completely by the metabolic activity of different microorganisms 3 . The interactions between different heavy metals and microorganisms might be due to antagonistic, additive effects or synergic. These interactions might be multifaceted and distinguished which depends on the type of heavy metal ion and microbial species consortium. The collective effect of different heavy metals may be toxicity or growth stimulation in the same microbial consortium assorted from the additive effect of the single metal ions 4 . Fungi have diverse mechanisms for bioremediation of heavy metals, including metal uptake by cell-wall components, accumulation inside the cell or extracellular chelation by phytochelatins and metal lothioneins 5 . Waste samples were collected from a polluted water source near Al-Madina electroplating industry, Alipur Chattha, Pakistan, in sterilized and cleaned 1 l glass bottles with stopper. All samples were treated with 372 mg/l EDTA as the chelating agent to reduce toxicity in samples burdened with heavy metals. During examination, the samples were fresh, and were occurred immediately after return to the laboratory.The fungi were isolated by filtration of the electroplating waste for collection of fungal propagules using 0.45 m pore size filter paper 6 . The fungal spore suspension was prepared in 50 ml of saline solution, and 100 l of spore suspension was inoculated in sterilized petri dish with modified culture medium consisting of aureomycin (0.35 mg/l), glucose (10 g/l), rose bengal (0.035 mg/l), Cu...

“…In order to find out optimum pH for maximum removal, a number of working solutions have been used with different pH [56][57][58][59][60][61][62][63][64][65] .Experimental data indicate that the biosorption of copper onto Kafal leaves increase very rapidly from the percentage removal 10.98 to 88.98 % under the pH range 1-6. At lower pH, about all active sites or the organic groups present on the surface of biosorbents undergoes protolysis.…”

The commonly used removal processes for heavy metals from contaminated wastewater and cited in the literature are chemical precipitation, electrowinning, carbon adsorption, reverse osmosis, preconcentrations, biosorption, phytoremediation etc. Among these, biosorption is comparatively efficient, low cost, economical and reliable process. Actually, the reliability of the process is depending on the choice of local biosorbents and their abundant availability. The waste plant leaves of Kafal were collected from the region of Kumaun hills of India. The paper explains that the Kafal leaf powder is a good biosorbent for the removal of Cu (II) ions from contaminated wastewater under batch study. The experimental data indicate that high removal efficiency is obtained at optimized conditions viz. higher pH, lower metal ion concentrations, moderate higher temperatures and higher dosage of biosorbents. The biosorption efficiency is recorded 88.98% at pH 6, 48.99% at contact time 70 minutes and 40.01 % at a higher dosage of biosorbent. The regression value is indicating that the order for all used isotherms model is Langmuir> Freundlich > Temkin.
