Treatment of colored effluent of the textile industry in Bangladesh using zinc chloride treated indigenous activated carbons

Investigation of dye adsorption onto activated carbon from the shells of Macoré fruit

“…The rate of adsorption of MB and MO in aqueous solution increases with the temperature of the reaction medium, in accordance with the study of Karim et al (2006). They showed that the adsorption capacity depends largely on the chemical interactions between carbon chemical surface groups and the adsorbent ion.…”

Comparison of oil palm shell-based activated carbons produced by microwave and conventional heating methods using zinc chloride activation

“…9. This phenomenon can be explained by the microwave irradiation method promoting higher concentrations of mesopores than the conventional method.…”

“…In chemical activation, dehydrating reagents such as KOH, K 2 CO 3 , ZnCl 2 and H 3 PO 4 are used to impregnate the raw materials, which influence their pyrolytic decomposition and inhibit tar formation [6][7][8]. Chemical activation generally results in the preparation of activated carbon with a higher carbon yield and a better developed pore structure relative to physical activation [9]. Zinc chloride is an activation agent that results in a high yield and a high surface area, and thus is widely used in the chemical activation method [10][11].…”

Characterization and Treatment of Textile Wastewater by Aquatic Plants (Macrophytes) and Algae

“…ZnCl2 utilization is an option method leads to the fabric weight increment and in dye uptake and permits easy recovery of NaOH. In addition, the procedure is eco-friendly and does not require neutralization by acetic or formic acid (Karim et al, 2006). In recent years, hypochlorite is being supplanted by other bleaching operators.…”
