在以纯碱为原料的非强酸性水溶液体系中采用酸碱滴定分析的误差来源及分析方法的改进

以三聚磷酸钠生产过程为例,论述了在以纯碱为原料的非强酸性水溶液体系中,由于反应不完全导致反应物中存在少量的碳酸盐,这部分碳酸盐干扰了用酸碱滴定法测量的中和度,并据此提出中和度分析改进方法.由此可以推广到其它以纯碱为原料的非强酸性水溶液体系中.

In sodium tripolyphosphate and process titrate analysis error and analysis method improvement

This article take the sodium tripolyphosphate production process as an example, elaborated in take Sodium carbonate as in the raw material non - strong acid watery solution system, because responded incompletely causes in the reactant to have the few carbonates, this part of carbonate has disturbed with the acid and alkali titrimetric method survey center and, and according to the above proposes and the analysis improvement method From this may promote to other take Sodium carbonate as in the raw materiat non - strong acid watery solution system.
