摘要
本文研究了测定时的萃取酸度,有机相与水相的体积比,酒石酸、抗坏血酸、硫氰酸钾和硝硫混酸用量对测定结果的影响,做了萃取分离后共存元素干扰测定,经与国家一级标准物质对比分析,验证结果与标准相符。
The paper studied the determiuatiou of micro molybdenum in rocks （soil） by flame atomic absorption spectrometry, including the acidity of extraction in determination, volume ratio of organic facies and water facies, the effects of tartaric acid, ascorbic acid, potassium and nitric - sulphuric acid volume, meanwhile, made an interference determination of coexisting elements after extraction and fractionation. Through the comparative analysis with the national first class standard samples, it is verified that result accords with the national standard.
