鉴定锌离子的一种新方法

A new method for identification of zinc ion

在罗丹明 B和亚铁氰化钾存在下 ,用 N-烯丙基 - N′- (对苯磺酸钠 )硫脲鉴定锌离子 ,其灵敏度 m=1.5μg,c=4 5μg· ml-1.实验了鉴定条件和应用 .

In the presence of rhodamine B and fernocyanide potassium, the zinc ion is identified by using N allyl N′ csodium P phenyl sulfonate) thiourea with the sensitivity and of m=1.5 μg and c=45 μg·ml -1 . Application and conditions of identification were studied.
