摘要
利用有机萃取剂１８－冠醚－６将Ｓｒ（Ⅱ）定量萃取分离后，采用吸光光度法对Ｓｒ（Ⅱ）进行定量分析。该法条件易于控制，重现性好，准确度高；应用于工业碳酸锶中Ｓｒ（Ⅱ）的测定结果良好。
Sr(Ⅱ) can be quantitatively separated by using 18 crone 6 as extractant,and determinated by spectrophotometry.This method is of high accuracy and selectivity,rapidity and simplicity.The method is applied to the determination of Sr(Ⅱ) in practical samples with satifactory results.
