Mg/Cr layered double hydroxide (LDH) was prepared and modified using an intercalation of oxalate anions ((COO)22-) to form Mg/Cr-(COO)22. The materials were then investigated malachite green removal determine the adsorption ability. Furthermore, desorption process regeneration adsorbent systematically conducted. on Mg/Cr- LDH Mg/Cr-(COO)22- fitted pseudo-second-order (PSO) kinetic model Freundl...
