Heavy metals, such as Pb(II), Cr(III), and Cd(II), are frequently discharged into the environment, resulting in a threat for health of living organisms. Microalgae represent an ecological method removal these pollutants.

Objective: This study aims to evaluate the effectiveness of ferric chloride (FeCl₃) and zeolite as adsorbents in reducing copper content dye pollutants batik wastewater. Theoretical Framework: Adsorption was chosen method for this due its suitability addressing challenges wastewater treatment. Modifications preparation represent an effective approach developing adsorption models assessing their performance. The adsorbent used is FeCl₃/zeolite, a composite material created through impregnation process that combines zeolite. working mechanism FeCl₃/zeolite involves coagulation processes conducted within laboratory-scale column. demonstrated by significant ability reduce heavy metal pollutants. Method: materials include FeCl₃. Zeolite activated using HCl enhance pore size. Subsequently, impregnated with FeCl₃ at ratio 3:1 3 hours under stirring 250 rpm. mixture then filtered separate filtrate precipitate. precipitate calcined 200°C 2 characterized SEM-EDX analyze adsorbent's properties. Finally, prepared applied treat Results Discussion: best results obtained from show achieved maximum reduction Cu 30% 27.86%. These were 450 grams time 10 minutes. Research Implications: are presented data, which can be reference or input management, particularly Additionally, findings serve basis environmental monitoring control efforts. Originality/Value: on Previous studies have not explored use

The development of widely sourced and efficient adsorbents is crucial for the adsorption lead from wastewater. A novel adsorbent, N-doped weathered coal (NWC), was prepared in this study using as precursor triethylenetetramine (TETA) N-source. performance behavior Pb(II) on NWC were investigated batch experiments. results demonstrated that has an towards Pb(II), with a maximum monolayer capacity 216.32 mg g−1 (25 °C). process spontaneous endothermic, importance chemisorption observed. mechanisms also analyzed based its physicochemical structure before after desorption N O functional groups, acting electron donors, promoted coordination making complexation dominant mechanism. Its contribution to mechanism could reach 44.81%. promising material both wastewater treatment resource utilization coal.
