چکیده
Wastewater from tanneries may ruin agricultural fields by polluting them with trace metals. The synthesis of nanoparticles (NPs) algal sources and their application could help in decreasing hazardous materials, for environmental safety. potential zinc oxide made Oedogonium sp. was evaluated removal heavy metals leather industrial wastewater. Synthesized (0 (control), 0.1, 0.5, 1 mg) were applied to treat wastewater using different concentrations effluents (0%, 5%, 10%, 15%, 100%) 15, 30, 45 d. collected dark brown black color very high pH (8.21), EC (23.08 μs/cm), TDS, (11.54 mg/L), while the chloride content 6750 mg/L. values biological oxygen demand (BOD) chemical (COD) ranged between 420 mg/L 1123 current study. Prior nanoparticles, Cr (310.1), Cd (210.5), Pb (75.5 mg/L) contents higher effluents. efficiency chlorides, Cr, Cd, improved 46.5%, 43.5%, 54%, 57.6%, 59.3%, respectively, following treatment mg after Our results suggested that green ZnO is a useful ecofriendly biotechnological tool treating tannery effluents, before they are discharged into water bodies, thus making soil environment clean.
