Synthesis of a novel porous Ag2O nanomaterial on ion exchange resin and its application for COD determination of high salinity water

Abstract This study reports for the first time on the synthesis of novel resin@P-Ag2O material and its application for reducing the chloride effect on COD determination of high salinity water. This engineered core–shell nanomaterial with cationic ion exchange resin core and porous Ag2O shell was pre...
