“…The adsorption is the easiest method, cheapest, effective method to remove dyes from solution and furthermore, the adsorbent can be reused [10], [11]. Various materials have been examined and implemented as adsorbent to remove dyes from water such as bentonite [12], kaolinite [11], zeolite [13], montmorillonite [14] and layered double hydroxide [15].…”

In this work, CuAl/Biochar (BC) composite was prepared by the coprecipitation method. The materials were applied to remove malachite green in aqueous solution. These materials were characterized using XRD, FTIR, BET and SEM-EDX analyses. The composite material was confirmed by X-ray diffractograms with reflection (002) at 24o and the appearance of new peaks at 1095 cm -1 . The BET result of CuAl/BC composite has larger surface area is 168 m 2 /g than 46 m 2 /g for LDH. The morphologies of composite materials show agglomeration and micro particle size. The result of the adsorption study indicated the composite material 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. Regeneration study of adsorbent CuAl/BC composite shows after four times reused, it still has high removal efficiency at 89%.

“…The adsorption amount was gradually increased with increasing adsorption time and reach equilibrium almost more than 100 minutes for all adsorbents. The results of adsorption time were fitted with pseudo first-order (PFO) and pseudo second-order (PSO) kinetic model as follows (He et al, 2019;Palapa et al, 2020):…”

<p>Composite based Ca/Al layered double hydroxide and biochar was prepared using mixing coprecipitation method at pH 10. Composite and the starting materials was characterized using X-ray, FTIR, BET, thermal, and SEM-EDX analyses. Furthermore, composite was used as adsorbent of methylene blue from aqueous solution. Several factors that influencing the adsorption process was investigated such as adsorption time, initial concentration, and temperature adsorption. The performance of composite as adsorbent was evaluated by reusability process. The results showed that composite has diffraction peak at 9.82, 17.99, 19.86, 20.55, 29.32, 30.95, 32.65, 36.61, 37.00, 43.49, 47.15, 55.12, and 56.12 deg, which was based on diffraction of Ca/Al layered double hydroxide and biochar as starting materials. The surface area of composite was 158.291 m2/g and largely higher than starting materials. The morphology of composite also shows regularity shape than Ca/Al layered double hydroxide and biochar. Adsorption of methylene blue on composite showed that higher adsorption capacity (32.535 mg/g) than starting materials. The reusability of adsorbent showed that composite can be used several times ad adsorbent without loss adsorption capacity and these phenomena indicated composite is excellent material to remove dye from aqueous solution.</p>
