摘要
研究了锗与桑色素在５．４ｍｏｌ／Ｌ磷酸介质中的荧光反应。本方法的检测限为４．４９×ｌ０￣（－３）ｍｇ／Ｌ，可用于植物样品中痕量锗的测定。方法的相对标准偏差为２．６１％～３．３２％，回收率为９９．３％～１０２．６％。
Fluorescent reaction of Ge(Ⅳ)with morin in 5.4 mol/L phosphric acidmedium has been studied. The limit of detection is 4.49× 10￣(-3)mg/L. It is a simple method withhigh selectivity and has been applied to the analysis of microamounts of Ge(Ⅳ)in plant samples.The relative standard deviations of 3.32%,2.61%and recoveries of l02.57%,99.26%are ob-tained.
