Synthesis and characterization of Ce(III) decorated Duolite resin and its removal performance of toxic anions from aqueous solutions

Nitrate and phosphate are major threats for water/ wastewater which grounds eutrophication's and methemoglobinemia diseases, respectively and also severely hazards the safety of aquatic beings and public health's. To deal with the purging of aqueous nitrate and phosphate contamination, a l...
