“…The characteristic of layered double hydroxide is flexibility where the anions in the interlayer can be exchanged dependent upon the application of layered double hydroxide [16]. One of the anions that can be exchanged is the oxalate anion [17], which aims to increase the interlayer distance [16].…”

“…Asci, 2016 [19] reported the removal of the dye Congo red and indigo carmine using layered double hydroxide Mg-Al-Cl. Meanwhile, Doungmo et al, (2016) [17] reported that the intercalation of oxalate ions on layered double hydroxide MgAl used for the adsorption of nickel ions had an adsorption capacity of 1310 mg/g. Palapa et al, 2020 [8] reported Cu/Al LDH intercalated with polyoxometalate anion was used for the adsorption of malachite green with the adsorption capacity of 55.866 mg/g and 149.253 mg/g, respectively.…”

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 to malachite green removal to determine the adsorption ability. Furthermore, the desorption process and regeneration of adsorbent were systematically conducted. The adsorption of green malachite on Mg/Cr- LDH and Mg/Cr-(COO)22- materials fitted to the pseudo-second-order (PSO) kinetic model and Freundlich isotherm model with an adsorption capacity of 33.784 mg/g (333K) for Mg/Cr LDH and 64.516 mg/g (333K) for Mg/Cr-(COO)22-. Thermodynamic data showed that the adsorption process was spontaneous and endothermic. Also, the appropriate reagent desorption study was found as hydrochloric acid and material regeneration studies exhibited a good recycling performance after 3 times cycles and, the Mg/Cr-oxalate showed a good performance for malachite green adsorption. It can be concluded that Mg/Cr--(COO)22- can adsorb the dye stuffs effectively.

“…Intercalated Mg/Cr LDH with oxalate anion has an XRD pattern that resembles Mg/Cr LDH. However, a shifting peak at 11° to 10° indicates an exchange of nitrate anions with oxalate (Giscard et al, 2016). The success of the intercalation process is supported by the data on increasing the interlayer distance from 7.62 Å on Mg/Cr LDH to 11.35 Å on intercalated Mg/Cr LDH.…”

“…The vibration peak at wavenumber 1381 cm -1 is assigned as the vibration of the nitrate ion at Mg/Cr LDH. According to Giscard et al (2016), the existence of an oxalate anion is confirmed by the presence of a vibrational peak around 1550 cm -1 and 1365 cm -1 . A decrease in the peak of the vibration at wavenumber 1381 cm -1 indicates that there has been an exchange of nitrate to oxalate ion on the interlayer.…”

“…The research conducted by Badri et al (2021), used intercalated Mg/Cr as adsorbent of Rhodamine B and Methylene blue with the adsorption capacities of 139.526 mg/g and 8.741 mg/g, respectively. The adsorption capacity obtained by (Giscard et al, 2016) in his research to remove nickel ions using intercalated Mg/Croxalate reached 1310 mg/g. Some of these studies prove that modification of LDH has a great ability to remove dye waste.…”

There are more than 100,000 dyes commercially available with more than 107 tonnes of dyes produced annually worldwide. These dyes are widely used by several industries such as foods, cosmetics, paper printings, and the textile industries as the largest dye consumers (Benkhaya et al., 2020). Dyes commonly used in industry can be classified as natural and synthetic dyes. According to Rubia & Bhardwaj, (2016), natural dyes have properties that are non-toxic, non-carcinogenic, eco-friendly, biodegradable, and easy to dispose of. However, the use of natural dyes is now starting to be replaced by synthetic dyes. Natural dyes are limited and more expensive than synthetic dyes. On the other hand, synthetic dyes are toxic on aquatic environment because of their non-durable, unstable, and lacking color variations (Zhao et al., 2018). Some of the most abundant synthetic dyes are methyl red (MR) and methyl orange (MO). These dyes have an azo functional group (-N=N-) and are classified as anionic dyes (Shan

Malachite green dye in industrial wastewater can be removed by the adsorption method. The adsorbents used in the adsorption method were Ni-Cr LDH, microcrystalline cellulose, and Ni Cr LDH/microcrystalline cellulose composite. Regeneration process of malachite green dye with the Ni-Cr/microcrystalline cellulose adsorbent resulted in the adsorbent having the highest percent adsorbed when compared to Ni-Cr LDH and microcrystalline cellulose adsorbents. This is proof that Ni-Cr/microcrystalline cellulose LDH composite adsorbent can be used repeatedly as much as five cycles. Ni-Cr LDH material and Ni-Cr/microcrystalline cellulose LDH composite were synthesized by the coprecipitation method and were successfully carried out by XRD characterization to see the stability of the structure. The results of XRD characterization of Ni-Cr/microcrystalline cellulose composite showed peaks at diffraction angles of 11°(003), and 60°(110) which are typical regions of LDH and at diffraction angle of 22°(020) which is a typical area of microcrystalline cellulose material. Ni-Cr LDH, microcrystalline cellulose and Ni-Cr/microcrystalline cellulose get optimum pH at 7 with wavelength malachite green at 618.8 nm, kinetic equation following PSO and isotherm following Freundlich with capacity maximum until 129.870 mg.g−1. FT-IR spectra display groups found in LDH and composites including O-H, NO3−, M-O also microcrystalline cellulose have groups C-O and C-H. SEM characterization found out the biggest particle size is 1,954 µm as much as 72 and EDX composite material contains elements of O, C, Ni, Cr, Na, and N.
