Radiation-induced grafting of glycidyl methacrylate onto cotton fabric waste and its modification for anchoring hazardous wastes from their solutions

Investigation of metal absorption and antibacterial activity on cotton fabric modified by low temperature plasma

“…Sorption-active natural and synthetic fibers and textile materials have been widely used in various industrial fields. Their electrochemical properties, such as transport number and electrical resistance, have been vastly improved (Sokker et al 2009). Zhao and Mitomo prepared a series of CM-cellulose/ chitosan blend hydrogels in a highly concentrated solution state with electron beam (EB) irradiation.…”

Removal of copper and lead from aqueous solution by carboxylic acid functionalized deacetylated konjac glucomannan

“…Moreover, many of copolymers of acrylic acid and polysaccharides are with poor mechanical strength and high water absorption capacity, which limit their actual application. Recently, the innovative technique of grafting the chains of a precursor-monomer on the inert polymeric matrix with subsequent modification has been widely studied [10][11][12]. In order to overcome these problems, weak acid biosorbent can also be prepared by indirect modification of biosorbent.…”

Sorption of acid and basic dyes on radiation-grafted Teflon scrap: equilibrium and kinetic sorption studies

“…The remaining epoxy groups were converted to diol groups by reaction with 0.5 M H 2 SO 4 for 2 h at 80°C. The conversion was determined gravimetrically [27]. To convert epoxy to triamine, grafted Teflon was allowed to react with diethylenetriamine in DMF (50:50) for 5 h at 80°C.…”

“…Various desired functional groups can be introduced onto the bulk polymer via the addition reaction of epoxy groups with amine derivatives and sodium sulphite, which is promising for applications of heavy-metal ion extraction [24,25], enzyme immobilization [26], and specific protein adsorption and dye removal [27] from wastewater effluents.…”
