一般描述
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.
应用
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.
用于金属回收、废水处理、海水净化等的螯合树脂。

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
