摘要
以 4 -叔丁基 - 2 (α-甲苄基 )苯酚 (t- BAMBP)萃取分离基体铯 ,磷钼杂多酸与结晶紫染料生成离子缔合物 ,在聚乙烯醇存在下 ,在水溶液中显色。在波长 5 45 nm处 ,其摩尔吸光系数可达 2 .0 1× 10 5L· mol-1·cm-1。方法的回收率为 97%— 10 1% ,相对标准偏差为 0 .8%— 2 .7%。
The method of 4-tert-butyl-2(α-methylbenzyl) phenol(t-BAMBP) extraction method was used to separate cesium from its solution.Micro amounts of phosphorus in high purity cesium chloride were determined by spectrophotometry with ion association of phosphomolybdate and crystal violet dye.The relative deviation of this method is in the range of 0.8%-2.7%.
