عنوان انگلیسی Heavy Metals Removal from Synthetic Wastewater Through Layered Double Hydroxide (LDH)(Mg-Al)-Hydrochar
چکیده انگلیسی مقاله An experiment was conducted to explore the potential use of Coconut Shell HydroChar (CSHC) using batch adsorption. CSHC-LDH (Mg-Al) is mixed with layered double hydroxide (LDH) to remove Ni (II), Cd (II), and Zn (II) from a ternary-metal solution (with a mixing ratio of 0.5:0.3:0.2). We investigated the effects of initial concentrations, pH, adsorbent dosages, and contact time through adsorption kinetic and isotherm studies. The optimal conditions that give higher removal percentages were: pH of 6 and 4, adsorbent dose 1 and 0.7 mg, initial metals concentration 250 mg/L, and the equilibrium time of 90 min for CSHC and CSHC/MgAl-LDH, respectively. The CSHC and CSHC/MgAl-LDH composite revealed a strong sorption ability to Cd (II), Ni (II), and Zn(II) in aqueous solutions with the Langmuir maximum adsorption capacity of 188.67, 204.08, and 222.22 mg/g and 312.5, 344.82, and 357.14 mg/g, respectively. The adsorption kinetic study revealed that the adsorption process followed second-order kinetics. The batch experiment results showed that the CSHC and CSHC-Mg-Al LDH were effective in the simultaneous removal of Ni (II), Cd (II), and Zn (II) to a significant extent. The CSHC-Mg-Al LDH composite has demonstrated considerable promise in removing heavy metals from wastewater. It offers the benefits of easy synthesis
and exceptional adsorption capability.
