“…Fig. 1(b) shows the diffractogram NiAl LDH/BC composite resembles the characteristic diffraction pattern of NiAl LDH and BC, as a similar finding by Palapa et al [23]. The composite of NiAl LDH/BC composites showed the peaks at 10°, 22°, 28°, 35°, and 60° corresponding to reflections of (003), (002), (006), (012), and (110), respectively, which indicated the materials have layer structure and carbon reflection from BC characteristic [36].…”

Rice husk biochar (BC) loaded NiAl layered double hydroxide (LDH) has been synthesized to form NiAl LDH/BC composite through a co-precipitation method. NiAl LDH/BC has been used as an adsorbent to remove malachite green from water efficiently. The specific surface area analysis revealed that the surface area of NiAl LDH/BC composite increased five times, from 92.6 to 438.9 m2/g, compared to the original NiAl LDH. The adsorption studies revealed that NiAl LDH/BC composite followed the pseudo-second-order kinetic adsorption model while the isotherm followed the Langmuir monolayer adsorption model. The maximum adsorption capacity of NiAl LDH/BC composite prepared with a ratio of 1:1 and 1:0.5 achieved 185.1 mg/g and 142.9 mg/g, respectively, which is twice higher than the pristine ones (NiAl LDH). The thermodynamic parameters, determined at 303, 313, 323, and 333 K, revealed that the adsorption process was spontaneous and endothermic. The NiAl LDH/BC composite was tested for three consecutive adsorption-desorption cycles to investigate its reusability performance. It is found that their adsorption performance slightly decreased to 71.8% and 68.3% for NiAl LDH/BC composite 1:0.5 and 1:1, respectively. Therefore, it could be considered that the synthesized NiAl LDH/BC exhibited a good and efficient adsorbent for malachite greed removal.

“…The same phenomena also occurred by other research, by using Zn/Al LDH removing MG with ∆H= 14.503 kJ/mol indicated endothermic process and ΔG= −13.513 kJ/mol denoted the adsorption was running spontaneous [35]. According to Palapa et al [36], ΔH and ΔG with the liquid phase were affected by various conditions such as concentration, temperature, and interaction between solid and liquid interfaces. Table 6 showed the comparison of the other adsorbents on MG adsorption.…”

Mg-Al-LDH is a chemical compound produced through co-precipitation technique and modified with Cu(NO3)2.6H2O to form Mg-Al/Cu. However, the research on the capability of these compounds for adsorbing mixtures of cationic dyes as well as malachite green (MG), methylene blue (MB), and Rodhamine-B (Rh-B) has not been carried out. Therefore, this research aims to determine the performance of Mg-Al-LDH and Mg-Al/Cu for removing cationic dyes. The materials used were characterized by using XRD powder, FT-IR, and N2 adsorption desorption. The Adsorption process was conducted by batch system and several effects were investigated, such as kinetic parameter, isotherm, and the temperature condition. The stability feature of Mg-Al-LDH and Mg-Al/Cu was obtained from the regeneration process in the five cycles. The results presented that Mg-Al/Cu was effectively produced, which was indicated by the formation of layer at 10.792° (003), 22.94° (006), 35.53° (112), 55.78° (110), and 56.59° (116). Mg-Al-LDH and Mg-Al/Cu were found to adsorbed MG than the other cationic dyes with adsorption capacity of 68.996 mg/g and 104.167 mg/g, respectively. The unique properties of Mg-Al/Cu includes, structural stability towards the reuse of adsorbent subsequently for five times, without significant decrease of adsorption capacity.

Numerous reports have elucidated the use of biochar (BC) to adsorb dyes from wastewater. However, its applicability for adsorbing Procion Red, which causes carcinogenic and mutagenic effects on aquatic life, has not been studied. In this work, biochar produced from rice husk in Sumatera, Indonesia was used as a biosorbent for Procion Red removal from aqueous systems. Rice husk-BC was characterised using X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, surface area specific analysis, and scanning electron microscopy (SEM) for mor-phological analysis. The characterisation showed a (002) reflection peak at 2θ = 23° with broad and quite intense diffraction, which indicates reflection of electromagnetic waves by silicates, oxides and carbon present in the rice husk-BC. The surface area and SEM morphologies confirm that after pyrolysis, the surface of the rice husk changed. The FTIR spectra confirm the presence of functional groups such as the carboxylic acids and aromatic compounds. The surface area of rice husk-BC was up to ten times that of its raw material. The results of adsorption studies indicate that adsorption of Procion Red on rice husk-BC follows a pseudo-second-order (PSO) reaction with a rate constant of 0.044 min-1 and Langmuir isotherm models with a coefficient of correlation close to unity. The maximum adsorption capacity increased from 36.900 mg g-1 for the rice husk to 84.034 for the rice husk-BC. Thermodynamic analysis showed positive enthalpy and entropy, indicating that Procion Red adsorption is endothermic; thus, the Gibbs energy values decreased with increase in temperature, indicating that high temperatures are favourable for the adsorption process. Furthermore, the study of adsorption of Procion Red on rice husk-BC and regeneration of the adsorption capacity of rice husk-BC showed the largest drop in the fourth and last cycle.
