摘要
采用阴离子分离柱 AS14 (4× 2 5 0 mm )分离 ,以电导检测器检测 ,以 3.5 mmol/ L Na2 CO3/ 1.0 m mol/ LNa HCO3为流动相 ,以标准曲线法为定量方法 ,测定氟化稀土中的氯离子。方法操作简便、快捷 ,结果准确、可靠。
In this paper, the study has been made on determining Cl - content in rare earth fluoride The method can determine 0 005% Cl -,its RSD ( relative standard deviation )is 9 30% The method is quick and accurate The method has been applied to the determination of Cl - in rare earth fluoride with satisfactory results
