Descrizione generale
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.
Applicazioni
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.

In this study two chelating resins containing iminodiacetic acid groups (Amberlite IRC 748 and Diaion CR 11) and a chelating resin based on sulfonic and diphosphonic acid groups (Diphonix) were investigated in order to separate Cr(III) from industrial effluents produced

The myeloperoxidase-derived oxidant hypochlorous acid (HOCl) is thought to contribute to endothelial dysfunction, but the mechanisms underlying this inhibitory effect are unknown. The present study tested the hypothesis that HOCl and L-arginine (L-Arg) react to form novel compounds that adversely
