Author(s): Dr. Arshi Rastogi
Abstract: The ability of non-viable Oedogonium hatei, green alga, to adsorb and remove Copper (II) metal ions from synthetic wastewater in a batch mode, is the subject of this research. The effects of key parameters such as sorption pH, temperature, initial metal ion concentration, contact time, and adsorbent dosage were investigated. The equilibrium data was applied to Langmuir and Freundlich isotherms, and it fitted well with Langmuir's model. The maximum adsorption capacity derived from the Langmuir isotherm was 56.18 mg/g at 90-minute contact time, 4.96 pH and 313K. The thermodynamic studies revealed that sorption onto algal biomass was feasible, spontaneous, endothermic, and physisorption process. Pseudo-first-order and pseudo-second-order kinetic models were applied to get insight into the adsorption process mechanism. Surface area calculation, elemental analysis, and FTIR spectral analysis were among the physical and chemical parameters of the algal biomass determined. According to the findings, Oedogonium hatei alga could be used as an adsorbent material to remove harmful copper (II) metal ions from wastewaters.
