The routine of low-cost adsorbents derived from plant or agricultural by-products as a substitute for expensive traditional removal methods of heavy metal from discarded streams has been investigated. The effectiveness of powder’s mulberry leaves in extracting Pb 2+ , Ni 2+ , Cu 2+ , and Co 2+  from an aqueous solution by batch adsorption at lab ambient temperature (25 ± 0.4°C) was investigated in this report. The impact of pH, contact time, biosorbent dosage, and preliminary concentration of metal ions on the exclusion percentage were investigated in experiments. The findings demonstrated that the elimination of metal ions by mulberry leaves powder was influenced by all adsorption parameters. At pH = 6 and 7, the maximum removal of Ni 2+ , Pb 2+ , Cu 2+ , and Co 2+  occurred. The obtained data were subjected to two different isotherm models Langmuir and Freundlich. The models of Pb 2+ , Ni 2+ , and Co 2+  results all complement the Langmuir isotherm well (R 2  = 0.99). However, the Freundlich isotherm was found to match Cu 2+  adsorption with (R 2  = 0.98). For Pb 2+ , Cu 2+ , Ni 2+ , and Co 2+ , the maximum monolayer adsorption potential was found to be 0.50, 2.88,1.14, and 1.15 mg/g, respectively. A sample of real industrial wastewater was collected and treated with mulberry leaf powder. The findings illustrate that mulberry leaves powder has a 69, 85, and 100% performance in removing Pb 2+ , Cu 2+ , Zn 2+ , ions, respectively. The findings of different treatments; synthetic and real wastewater, suggest that mulberry leaves powder may be applied as a low-cost alternative to more expensive heavy metal adsorbents. The pseudo-second-order kinetic model was applied to fit the model and describe the adsorption mechanism.
