Abstract
A six-fold iodometric amplification method is described for the determ ination of arsenic and antimony in organic compounds. It is based on t he oxidation of arsenite (antimonite) with periodate and subsequent re action of arsenate (antimonate) and iodate with iodide. Average recove ries were 99.8 and 99.5%, average standard deviations 0.22 and 0.34% f or As and Sb, respectively.
