铬天青S差示光度法测定铍精矿、绿柱石中氧化铍量

Determination of Beryllium Oxide in Beryllium Concentrate and Beryl by Chromazurol S Differential Spectrophotometry

铬天青S光度法能够准确测定氧化铍,经引入1,2—环己二胺四乙酸(CYDTA)等高浓度、高络合剂,使方法有了优良的抗干扰能力,操作较为简便。在此基础上,对这一分析方法开展了进一步研究,从样品加工开始,严格控制条件,能够准确测定5%~14%氧化铍,可以代替重量法并及时提出可靠的分析报告,该法用于实验室检测样品分析,已经取得较好结果。

Chromazurol S spectrophotometry can accurately determine beryllium oxide.The introduction of high concentration and high complexing agents such as 1,2-cyclohexanediamine tetraacetic acid(CYDTA)has provided the method with excellent anti-interference ability and relatively simple operation.On this basis,further research has been carried out on this analytical method.Starting from sample processing,strict control of conditions can accurately determine 5%to 14%beryllium oxide,which can replace the gravimetric method and provide reliable analytical reports in a timely manner.This method has been used for the analysis of laboratory test samples and has achieved good results.
