摘要：

A six-fold iodometric amplification method is described for the determination of arsenic and antimony in organic compounds. It is based on the oxidation of arsenite (antimonite) with periodate and subsequent reaction of arsenate (antimonate) and iodate with iodide. Average recoveries were 99.8 and 99.5%, average standard deviations 0.22 and 0.34% for As and Sb, respectively.
