Radiation graft copolymerization of phosphorous containing monomer on CMC-based hydrogel for metal adsorption

摘要

Over 120 years, more and more reports have been devoted to phosphorus-containing polymers, mainly due to their fire resistance, metal-adhesion properties and anti-corrosion1. Moreover, phosphate groups are known to show excellent chelating properties. Thus, phosphorylated polymers were used as metal-chelating products, as cation exchange materials and for the treatment of pollution2. Nevertheless, trying to lessen these phosphorus-containing polymers impact on the environment and toward “green chemistry” by replacing phosphorylated additives and petro based chemicals is currently challenging both research and industry. The use of bio-based polymeric backbones might allow the reduction of toxic bio-accumulation by using renewable materials and by achieving more easily biodegradable. In addition, reuse and recycling become possible.
