Abstract Fe contamination is one of the frequently found contamination problems in ion exchange resins.No matter it is cation resin or anion resin

it is quite possible to be contaminated during processing.To messure Fe content in the resin

the usual way to do that is by hydrochloric acid leaching.Howev er

this method has come disadvantages

such as too many operation procedures

longer operation time and large errors in measurement.Introduced in this paper is another method of fast measurement and some studies on the physicochemical and process characteristics of the contaminated gel styron resin.
