盐水中硫酸钠浓度测定方法的改进

Improvements in determination method for sodium sulfate concentration in brine

介绍络合滴定测定盐水中硫酸钠浓度的方法,加入乙醇取代加热煮沸,缩短了分析周期,并根据试样中硫酸钠的浓度改变样品的稀释倍数,保证了SO2-4沉淀完全,从而保证了测定结果的准确性。

A compleximetric determination method for sodium sulfate concentration in brine was introduced. The addition of alcohol substituted for boiling, thus the determination time was shortened. The sample was diluted on the basis of sodium sulfate concentration in the sample, thus S042- precipitated completely and the accuracy of determination results was ensured.
