AMBERLITE™IRC748i螯合树脂是一种大孔道亚胺二乙酸螯合阳离子交换树脂，对氯碱盐水中的钙，镁和锶具有高选择性。 AMBERLITE IRC748i树脂对各种工艺和废水中的碱金属离子也表现出对重金属阳离子的高选择性。选择性是通过亚氨基二乙酸官能团与大孔树脂基体化学键合来实现的。由于AMBERLITE IRC748i树脂对金属的优先选择性和优异的动力学性能，即使在高浓度的钠或钙盐存在的情况下，也可以从溶液中去除大部分金属，而且金属泄漏极低。 AMBERLITE IRC748i树脂的大网状结构具有很高的抗渗透性，并具有优异的物理稳定性。

AMBERLITE™ IRC748i Chelating Resin is a macroreticular, iminodiacetic acid chelating cation exchange resin with high selectivity for calcium, magnesium and strontium in chlor-alkali brines. AMBERLITE IRC748i resin also exhibits high selectivity for heavy metal cations over alkali metal ions found in various process and waste streams. Selectivity is achieved by the iminodiacetic acid functionality chemically bound to a macroreticular resin matrix. Because of the high preference of AMBERLITE IRC748i resin for metals and excellent kinetic performance, it can remove most metals from solutions even in the presence of high concentrations of sodium or calcium salts, with very low metal leakage. The macroreticular structure of AMBERLITE IRC748i resin is highly resistant to osmotic shock and has excellent physical stability.
