| Abstract: | Trace boron and iodine in the rice, straw and other vegetable samples are determined by FAAS. BO33- and IO3- are transformed respectively into BF4- and I- , then complxed withCd(phen)3]2+. Cadmium in the complex compound of boron or iodine is extracted by nitrobenzene as an extractant, and is determined by FAAS, thereby boron and iodine are indirectly determined by the method. The recovery of boron and iodine is 92. 8%-102. 4% and 97. 2%-106. 7% , respectively. |
