“…2–5 Methyl orange degrades into intermediate products such as sulfonamides, aniline, N ′ N dimethyl benzyl-1,4-diamine, benzenesulfonic acid, and 1,4-diaminobenzene, which exhibit acute toxicity, and corrosive, carcinogenic and mutagenic properties. 6 Since synthetic dyes are resistant to biodegradation, a multitude of studies investigated their removal using electrocoagulation, 7 flocculation, 8 filtration, 9 chemical oxidation, 10 electrochemistry, 11 and ozone treatment. 12 The adsorption method prevents the conversion of methyl orange into toxic intermediates while offering effective, inexpensive recovery of the synthetic dye.…”

“…Therefore, it is necessary to search for simple, efficient, and economical ways to treat dye wastewater before releasing into public water. Currently, numerous methods have been employed to removal dyes from wastewater including adsorption [2,3], membrane filtration [4,5], advanced oxidation processes [6,7]. Among these methods, adsorption is one of the most popular methods for water purification due to its simplicity, cost effectiveness, high efficiency and no IOP Publishing doi:10.1088/1755-1315/1139/1/012003 2 other chemical required to promote the reaction rate between the adsorbent and adsorbate.…”

The development of sustainable adsorbent materials for removing pollutants from water is of great interest for environmental remediation and human safety. This work presents the beneficial use of cassava rhizome (CR) to produce economical and efficient carbonaceous adsorbents for dye removal. CR derived activated carbons (AC) and magnetic AC were fabricated by one-pot hydrothermal carbonization in the presence of ZnCl2 and ZnCl2/FeCl3 respectively, followed by pyrolysis at 800 °C. Porosity tuning and degree of magnetization of as-prepared carbons were achieved by varying the amount of ZnCl2 and FeCl3 as an activating agent and source of magnetic particles respectively. The result indicated that the optimal condition to obtain ACs with a high SBET (1405 m2/g) and the largest mesopore volume (0.54 cm3/g) was using the weight ratio of ZnCl2 to CR of 3 (3AC). While, the magnetic mesoporous carbon with the highest SBET (554 m2/g) was yielded when addition of FeCl3 into the reaction mixture with a FeCl3 to ZnCl2 weight ratio of 1(3AC-1M). 3AC and 3AC-1M were tested as adsorbents to investigate the adsorption efficiency of methylene blue (MB) in water. The adsorption behavior of MB on 3AC and 3AC-1M were monolayer adsorption based on the Langmuir isotherm model with R2 of 0.9993 and 0.9953, respectively. 3AC showed the MB adsorption capacity of 274 mg/g which is comparable to that of commercial ACs. 3AC-1M that adsorbs MB with the maximum capacity of 102 mg/g, was separated from aqueous solution easily using an external magnet. This study demonstrates that the carbon precursors from biomass waste as CR can be conveniently converted into efficient carbonaceous adsorbents and functionalized for example by adding magnetic properties into the carbon structure to enable manipulations in industrial operations.

Introducing the cellulose chain cationic groups in the modification process completely changes the charge on the cotton surface from negative to partially or totally positive. That allows the electrostatic attraction and simultaneous exhaustion and fixation of reactive dyes. This reaction can be carried out without salt and alkali at room temperature. Similarly, the reaction between reactive dye and an alone copolymer ([IME]+Cl−) with TLC chromatography was confirmed. The analysis with the use of particle optimisation with MM+ molecular mechanics and quantum-chemical calculations PM3 by the method of all valence orbitals confirmed the experimental results of the high activity of the nucleophile formed on the hydroxyl group in the chain of a modifier. It was found and experimentally confirmed that the reactive dyes during the dyeing process of the cotton cationised with copolymer (chloromethyl)oxirane -1H-imidazole ([IME]+Cl−) create covalent bonds due to a reaction with the hydroxyl group located in the modification agent instead of with the hydroxyl group in the glucopiranose ring. Although the dyeing takes place in very mild conditions, a high degree of setting is achieved, comparable to conventional methods.
