A NEW REAGENT FOR CONCENTRATING CHROMIUM ION Cr(Ⅵ)──CYANURICTRIAMIDE FORMALDEHYDE RESIN

Wu Shilan(Department of Chemistry,Tianjin Normal University)Sun Yuanxia(Experimental Center,Tianjin Normal University)  
he trace chromium ion Cr(Ⅵ) existing in nature or wastewater can be concentrated by cyanurictriamide formaldehyde resin exchange.This paper studies a direct Cr(Ⅵ) concentrating method and the concentrated ability,acidity and recovery rate for Cr(Ⅵ)ion have also been discussed.
