General description
Diaion CR11 is chelating resin with iminodiacetic acid groups. It is considered effective in the removal of chromium trivalent from aqueous solutions. This resin in the Na+ form at 50°C is seen to exhibit high sorption capacity.
Application
Chelating resin for metal recovery, wastewater treatment, brine purification, etc.
Diaion CR11 was used to prepare phosphate buffer, required to measure rate constants of the reactions of hypochlorite with L-Arg and taurine by stopped-flow spectrophotometry.
