Removal of dyes from water using crosslinked aminomethane sulfonic acid based resin

Abstract

A new polymeric resin with amino sulfonic acid pendant functions has been prepared for the extraction of acidic and basic dyes from water. Beaded polymer supports were prepared by suspension polymerization of vinyl benzyl chloride (0.9 mol) and ethylene glycol dimethacrylate (0.1 mol). The resulting copolymer beads were modified with amino methane sulfonic acid. The dye adsorption capacity of the resin was found as 0.16 g dye/g resin for ramazol black and 0.15 g dye/g resin for crystal violet. The pH depending measurements and dye sorption kinetics of the resin were also investigated.

Evaluation of a functionalized copolymer as adsorbent on direct dyes removal process: Kinetics and equilibrium studies

“…The maximum adsorption capacity of StDVB‐NMe for dye removal is more suitable values when compared with the Sips maximum adsorption capacity. From the sorption isotherm curves (saturation value) the maximum adsorption capacity of the StDVB‐NMe was determined (Table III); the obtained results are higher or comparable with other published data: 56.2–61.3 mg g −1 ,42 29.98–37.92 mg g −1 ,55 20.9–21.6 mg g −1 resin,56 and 160 g g −1 resin 57…”

Purification of phenol-contaminated water by adsorption with quaternized poly(dimethylaminopropyl methacrylamide)-grafted PVBC microspheres

“…Poly(vinylbenzyl chloride) (PVBC) is a typical PS-type synthetic polymer that has been employed in recent years for the synthesis of high-efficient adsorbents for the removal of metal ions or organic pollutants from wastewater 30,31 because the abundant chloromethyl groups of the PVBC surface can serve as anchor sites to introduce specic functional groups, such as amino groups (-NH 2 ), hydroxyl groups (-OH), carboxylate (-COOH), and sulfonic groups (-SO 3 H), for their enhanced adsorption capacity and selectivity of polymeric adsorbents. 32 Different approaches have been reported to prepare PVBC-based adsorbents, including amination of PVBC and subsequent alkaline ion exchange to produce polyvinyl benzyl trimethylammonium hydroxide (PVBTAH)-zeolitic imidazolate framework (ZIF-8), 33 graing of PVBC beads with primary amines, 34,35 amino methane sulfonic acid, 36 proline, 37 aminocarboxylic acid, 38 quaternization of the PVBC microspheres with ethyl piperazine, 39 and N,N-dimethylethanolamine (DMEA). 40 Among these methods, surface-initiated atom transfer radical polymerization (SI-ATRP) provides a versatile approach to precisely prepare functional polymer brushes of narrow polydispersity, well-dened architecture, controllable thickness, and composition.…”

Adsorption of textile dyes present in aqueous solution and wastewater using polyelectrolytes derived from chitosan

“…The values of the monolayer capacity for P3 are greater than those reported for cationic dyes on polymethacrilyc acid hydrogels (102–170 mg g −1 ) and other ionic exchange resins (35–170 mg g −1 ) . Regarding the adsorption of anionic dyes, the results are similar to those obtained from cationic polyelectrolytes synthesized from commercial monomers (64.46–68.60 mg g −1 ) and greater than those observed in commercially available ionic exchange resins (25.5–46.1 mg g −1 ) . Also, the adsorptive capacity of P3 for anionic dyes is similar to that reported for chitosan (67–339 mg g −1 ) .…”
