STUDY OF TRACE CD IN THE RICE BY IDMS

The paper was described that the rice was digested by HNO3-HCIO4.A lot of organic materials were removed. Strong base type anion exchange resin (T910#) were used to separate a large number of K. Na. Ca. Mg and other metal ions in the rice. Then, the trace Cd was determined by IDMS. the results were perfectly satisfaction.
