| Summary: | The heavy metals are exceptionally responsive at low fixations and can accumulate in the food web, causing extreme general wellbeing concerns. Remediation utilizing customary physical and substance techniques is uneconomical and creates huge volumes of compound waste. Bioremediation of risky metals has gotten impressive and developing enthusiasm throughout the years. Adsorption of Cr3+and Fe2+ from its aqueous solution on biosorbent Mango leaf powder (MLP) was prepared from matured Mango (Mangifera indica) leaves. The study was carried out by batch adsorption experiments using atomic adsorption spectroscopy upon various parameters used to assess their impact on the adsorption of metal ions. The achieved results evidenced the adsorption of Cr3+and Fe2+on MLP is better. The higher adsorption ability was shown about 237.5 and 227.5 mg/g respectively at 50 mg/L concentration of metal ions and 100 mg/L of MLP. Besides, the adsorption of Cr3+and Fe2+ on MLP was found to be fitted with the Freundlich isotherm. Thermodynamic results showed the sorption process is feasible, spontaneous, and endothermic. Kinetic parameters had shown that the adsorption of Cr3+ and Fe2+ ions found as pseudo-second-order kinetics; also this current study proposing that the adsorption process is presumably chemisorption. The consequences of this examination will be helpful for the expulsion of metals from water containing substantial metal ions. Further, this assessment is prescribed to recognize and evaluate the possible wellspring of those major and substantial metals to the wastewater. Thus, the current investigation emphatically prescribes the mango leaf powder used to expel the metals particles from wastewater.
