Variation of M2+ (Ni and Zn) in Cellulose-based M2+/Cr Composite Materials to Determine Adsorption and Regeneration Abilities on Phenol Removal

Cellulose-based Ni/Cr (Ni/Cr-C) and cellulose-based Zn/Cr (Zn/Cr-C) composite materials have been successfully carried out, which is indicated by the XRD, FTIR, BET analysis. Layered double hydroxide (Ni/Cr-LDH) increased surface area from 0.128 m2/g to 2.207 in Ni/Cr-C composites, layered (Zn/Cr-LDH) also 0.133 3.714 Zn/Cr-C composites. The pHpzc of material this study pH 5.94-8.43, while optimum all 9. Ni/Cr-LDH experienced an increase adsorption capacity after becoming a composite, 8.985 mg/g 24.510 mg/g, Zn/Cr-LDH 13.263 30.960 Zn/Cr-C. has greater ability than Ni/Cr-C. Kinetic isotherm model followed PSO kinetic with contact time at 70 minutes Freundlich isotherm. can be used repeatedly regeneration process until 4th cycle.
