酸碱滴定法测定焦炭钝化改质剂中硼含量

Acid-base Titration Method for the Determination of Boron Content in Coke Passivation Modification

采用酸碱滴定方法,不用酸度计进行滴定,测定焦炭钝化改质剂中硼含量。确立了分析方法的最佳实验参数并建立了焦炭钝化改质剂中硼含量分析的作业指导书,并申报了公司的一项技术秘密,即将申报公司的检验企业标准。采用实验方法测定实际样品所得加标回收率为98.28%-101.43%,测定结果的标准偏差为0.37%-0.43%。方法用于采购验证样品分析,具有操作简便,分析快速等优点。

acid-base titration method is used without acidity titration and determination of boron content in coke passivation quality.Establishes the optimum parameter analysis method and set up analysis of boron content in coke passivation quality instruction,and declared the company a technical secret,is about to declare the inspection standard of the company.Recoveries obtained experimental method was used to determine the actual sample for 98.28%-101.43% determination of standard deviation is 0.37% ～ 0.43%.Analysis method for purchase validation samples,simple,fast,and so on.
