摘要
在弱酸性条件下,硫酸根与钡离子结合生成硫酸钡沉淀物,选择G4坩埚并利用循环水式真空泵进行沉淀过滤、洗涤,并于烘箱中烘干、称量,计算硫酸钠含量。这种方法缩短了样品分析时间。
Precipitation of barium sulfate was generated when Sulfate and barium ions was combined under acidic conditions. G4 crucible was chosen and circulating water pumps was used. The precipitation of barium sulfate was filtered, washed and dried in an oven, and weighed to calculate the sodium sulfate content, in this way n the sample analysis time was shortened.
