摘要: A catalytic determination of iodine using the As(III)/Ce(IV) reaction has been developed. The difference in rate due to catalysis by iodide was measured spectrophotometrically at 310 nm. Optimum conditions were investigated order obtain a greater sensitivity iodine. method can be satisfactorily used for samples containing 0.4 10.0 ng range, with an overall error less than 6 %. serum, and gives results which compare favorably present clinical chemistry procedure.
