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。
在弱痠性條件下,硫痠根與鋇離子結閤生成硫痠鋇沉澱物,選擇G4坩堝併利用循環水式真空泵進行沉澱過濾、洗滌,併于烘箱中烘榦、稱量,計算硫痠鈉含量。這種方法縮短瞭樣品分析時間。

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.
