【摘要】 本文报道了一种简便可靠的测定富硒酵母中硒含量的方法。采用双氧水:高氯酸:硫酸=3:3:1的消化液处理样品,用联苯胺比色法测定样品总硒含量,回收率达96.9%,变异系数为1.64。

【Abstract】 The determination of selenium in selenium - enriched yeast by diphenylamine spectrometry was studied. When a digesting solution of hydrogen peroxide: hyperchloric acid: sulphuric acid = 3:3:1 was used, the recovery of the method was about 96. 9%, while the variation coeffient of the measurement was 1. 64.
