Study on the Adsorption of Acid Violet 1 by Polymer Microspheres
Monika Wawrzkiewicz, et al. Molecules. 2020, 25(22), 5247.
Acid violet 1 is a synthetic, water-soluble dye that belongs to the class of dyes known as triarylmethane dyes. A copolymer microsphere of divinylbenzene copolymer with glycidyl methacrylate functionalized with triethylenetetramine (DVB-co-GMA-TETA) resin has been synthesized for the removal of acid dyes (e.g., Acid violet 1). The adsorption capacity of this adsorbent for acid violet 1 can reach 172 mg/g. Adsorption mechanism of acid violet 1 · The dye adsorption on DVB-co-GMA-TETA probably takes place as a result of physisorption and chemical interactions. · The electrostatic interaction (ionic bond) between the positively charged functional groups of the resin and the negatively charged sulfonic groups of the dyes are created. · Additionally, hydrogen bonds and π-π interactions between the aromatic rings of benzene present in the resin matrix and dyes may occur.
Adsorption and Advanced Oxidation Removal Strategies for Acid Violet 1
Wawrzkiewicz M, et al. Processes, 2021, 9(11), 1911.
Acid violet 1 is an azo dye that degrades into toxic aromatic amines in the environment. Adsorption and advanced oxidation process (AOP) have proven to be two effective techniques for the removal of acid violet from aqueous solutions. · Adsorption removal for acid violet 1 A strong alkaline anion exchanger with a macroporous structure was used to perform adsorption and desorption tests on acid violet 1 at room temperature using intermittent technology. Dye removal efficiencies of more than 99% can be achieved after 240 minutes using anion exchange resin in 100-500 mg/L solutions. · Advanced oxidation process for acid violet 1 Hydrogen peroxide (H2O2) or peracetic acid (PAA) was used as the oxidant to evaluate the decolorization and mineralization effects of the AOP process on acid violet under different oxidation conditions. Compared with H2O2, Fenton reaction, PAA/Fe2+ and PAA/Fe2+/sunlight systems are more effective for the decolorization and mineralization of acid violet 1 solution.
