纤维素酯微孔萃取膜(核工业部三所与北京化工学校工厂研制)可用于化学分析分离,富集痕量成份元素。随膜上的萃取剂不同,而有不同的萃取功能。我们用该产品的C(即8-羟基喹啉)膜、对钴、镍、锌的富集条件做了初步实验并对发锌样进行对照实验,结果较为满意。 实验部分 一、仪器和试剂 本实验中,除了洗发用的洗净剂外,所用其余试剂均为分析纯。 C膜是由核工业部三所提供。
Cellulose ester microporous extraction membrane (three of the Ministry of Nuclear Industry and Beijing Chemical School factory development) can be used for chemical analysis, enrichment of trace elements. With the extractant on the film is different, but have different extraction functions. We use the product of C (ie 8-hydroxyquinoline) film, cobalt, nickel, zinc enrichment conditions made a preliminary experiment and hair zinc control experiments, the results are satisfactory. Experimental part A, instruments and reagents In this experiment, in addition to shampoo with detergent, the rest of the reagents used are of analytical grade. C membrane is provided by the Ministry of Nuclear Industry three.
