本文根据在近中性溶液中 ,痕量锰 (Ⅱ )对高碘酸钾氧化氨基黑 10B褪色反应的催化作用建立了检出极限为 0 .0 2 μg/mL、线性范围为 0 .45～ 9.5 μg/mL的测定锰的新方法 ,适用于人发、人尿中痕量锰的测定。
In this paper, based on the catalytic effect of trace manganese (Ⅱ) on the discoloring reaction of amido black 10B oxidized by potassium periodate in a near-neutral solution, the detection limit was 0. 02 μg / mL and the linear range was 0.45 ~ 9.5 μg / mL The new method for the determination of manganese is suitable for the determination of trace manganese in human hair and human urine.
