Abstract

The application research of the exchange capacity of macroporo us and gel-typed anion resin,and the exchange capacity of resins with uniform a nd ununiform diameters have been studied by using the FIA spectrophotometry,whic h was developed. This method has good relativity with the result of GB methods( the correlation factor r = 0.990).Its reagent consumption is low, the operatio n is simple, and the automatization level is high. The working exchange capacity, equilibrium exchange capacity, total exchange capacity,exchange speed and uti lity rate can be determined at one time. It can also be used for the theoretical research of the exchange performance of many other anion resins.
