本文介绍了利用ELTA为萃取剂,萃取分离铸铁中微量钼的条件以及采用1%(V/V)氨水进行反萃取后应用AAS测定水相中钼的分析方法。试验表明:钼在0～100μg/g浓度范围内呈良好线性关系,相关系数为0.9992。方法的相对误差为-3.31～-7.80%,相对标准偏差为3.39%～3.90%。
This article describes the use of ELTA as extractant, extraction and separation of trace amounts of molybdenum in cast iron conditions and the use of 1% (V / V) ammonia stripped after the application of AAS Determination of molybdenum in the aqueous phase analysis method. The results showed that there was a good linear relationship between molybdenum concentration in the range of 0 ~ 100μg / g, the correlation coefficient was 0.9992. The relative error of the method was -3.31 ~ -7.80% and the relative standard deviation was 3.39% ~ 3.90%.
