Modification of alginate through the grafting of 2-acrylamidoglycolic acid and study of physicochemical properties in terms of swelling capacity, metal ion sorption, flocculation and biodegradability

Effects of gamma irradiation and moist heat for sterilization on sodium alginate

“…By changing the physicochemical and biological properties, such as concentrations, pH value and viscosities, it is possible that the alginate is used to control drug release. Among polysaccharides, sodium alginate (SA) is a biocompatible, non-toxic, non-immunogenic and biodegradable natural linear polysaccharide [2][3][4][5], which is widely applied in the fields of medical and industrial.…”

Research on a novel poly (vinyl alcohol)/lysine/vanillin wound dressing: Biocompatibility, bioactivity and antimicrobial activity

“…Hydrogels made from natural materials, such as alginate [10], chitosan [11] and collagen [12], used to be applied to wound healing due to their biocompatibility [13] and biodegradability [14]. However, these hydrogel dressings were limited because of their relative low mechanical properties.…”

Gellan gum-g-N-vinyl-2-pyrrolidone: Synthesis, swelling, metal ion uptake and flocculation behavior

“…The grafting ratio (%G = 98.4-121.8), add on, efficiency, conversion and rate of grafting have been found to increase and homopolymer decrease continuously with increase in concentration of sulphuric acid from 2 × 10 −3 to 6 × 10 −3 mol dm 3 (Table 1d). Beyond this the grafting parameters decrease when the sulphuric acid concentration increase from 6 × 10 −3 to 10 × 10 −3 mol dm −3 .This behavior might be due to the formation of inactive H 2 SO 5 species [24], thus the concentration of active species (HSO 5 − ) decreases, resulting in production of less primary free radicals.…”

“…For flocculation studies, coking and non coking coals used were received from Steel Plant, Bokaro, India Procedure for graft copolymerization Scheme 1 represents the general procedure for the preparation of graft copolymer(gellan gum-N-vinyl-2-pyrrolidone). Procedure for grafting has been followed as reported in our previous publication [24].…”
