离子膜氢氧化钠中硫酸盐含量的测定

Determination of sulfate contents in ionic membrane sodium hydroxide

介绍了用分光光度法测定离子膜氢氧化钠中硫酸盐含量的原理和操作方法,测试结果表明,该法优于重量法与比浊法。

Principles, operation method, results of determined method that sulfate contents in ionic membrane sodium hydroxide tested by spectrophotography were introduced. It showed that the process was better than the gravimetric method and nephelometry.
