Abstract
In this work, CuAl/Biochar (BC) composite was prepared by the co-precipitation method. The materials were applied to remove malachite green in aqueous solution. These materials were characterized using XRD, FTIR, BET and SEM analyses. X-ray diffractograms confirmed the composite material with reflection (002) at 24o and new peaks at 1095 cm-1. The BET result of CuAl/BC composite larger surface area is 168 m2/g than 46 m2/g for LDH. The adsorption study indicated the CuAl/BC composite follows pseudo-second-order (PSO) and Langmuir isotherm models. The maximum adsorption capacity of malachite green using CuAl/BC uptake is 164.316 mg/g. The thermodynamic analysis indicates that the malachite green adsorption is spontaneous, endothermic. The regenerative study of adsorbent CuAl/BC composite shows four times reused, and it still has high removal efficiency at 89 %.
