“…There have been many physiochemical methods studied to treat dye-containing wastewater, but adsorption is the most appropriate because it is economical, feasible, and can work at high dye concentrations. Many agricultural wastes have been used for the adsorption of toxic aqueous pollutants such as walnut shell [5], Punica granatum [6], leechi peel [7], Schleichera oleosa bark [8], rice husk derivatives [9], Onosma bracteatum [10], Coriandrum sativum [11], and most recently, rubber seed pericarp [12]. For the adsorption of toxic pollutants, other synthesized adsorbents such as MOF-5/Cu [13], CuCl-MIL-47 [14], mesoporous silica/DZ [15], and magnetic mesoporous silica [16] have also been used.…”

Neolamarckia cadamba leaves were used as an adsorbent for methylene blue removal as well as for the reduction in the water quality parameters of the sewage belts of Yamuna River in Allahabad, Uttar Pradesh, India. A variety of water quality parameters were assessed, including chemical oxygen demand, biological oxygen demand, total dissolved solids, conductivity, hardness, pH, and temperature. A great deal of degradation in the water quality parameters collected from three locations within the Yamuna River in Allahabad, Uttar Pradesh, India, has been observed by treating with Neolamarckia cadamba leaves. The adsorption studies were carried out by the batch method, and the effect of various parameters such as contact time, pH, initial concentration, and temperature was assessed. The maximum removal of methylene blue was obtained at pH 5 after 120 minutes of equilibrium time. In addition to fitting the Langmuir isotherm most accurately, the adsorbent also followed pseudokinetics of the second order. The maximum monolayer adsorption capacity of used biomass was 101 mg/g using 50 mg/L methylene blue solution. It is evident from the thermodynamic data that the adsorption is exothermic. Also, the spontaneity of the interaction between adsorbent and adsorbate decreases with temperature. Energy-dispersive X-ray spectroscopy, scanning electron microscopy, and Fourier transform infrared spectroscopy techniques were used to characterize the adsorbent. SEM images revealed that the biomass consisted of irregular spherical lumps with a porous structure, which provided effective adsorption sites. A chemical composition analysis of the biomass by EDAX shows that the chemical composition of oxygen and carbon decreases, whereas nitrogen’s chemical composition increases.

“…The biosorption process is the ability of biologically derived materials to adsorb the toxic aqueous pollutants. Both adsorption and biosorption are economically feasible methods and have many advantages in comparison to other available water treatment techniques (Kashif Uddin & Fazul Rahaman, 2017). Chao et al used three different agricultural wastes to prepare biosorbents for heavy metals removal in a fixed bed column (Chao et al, 2014).…”

In this present study, phosphate-modified Saraca asoca bark powder was used to bring out an efficient bioadsorbent for nickel (II) ion uptake from wastewater. The bioadsorbent was characterized using scanning electron microscopy and Fourier transform infrared spectroscopy. The effect of various parameters such as pH, contact time, initial concentration and temperature were examined using the batch experimental process. The adsorption of nickel(II) was found to increase with the increase in concentration. The used bioadsorbent proved to be highly efficient and adsorbed 96% of nickel(II) from the aqueous solution at pH 4-6. The adsorption equilibrium data were described by using various isotherm models i.e. Langmuir, Freundlich, Temkin and Dubinin-Radhuskevic. Langmuir and pseudo-secondorder-kinetic were found to be best-fitted isotherm and kinetic models, respectively. Thermodynamic parameters showed the spontaneous and endothermic nature of the adsorption process. Succesful desorption of Ni(II) confirms the reusability of the bioadsorbent. The samples from real electroplating wastewater were collected to better examine the applicability of phosphate-modified Saraca asoca bark powder towards nickel(II) ions.
