水垢中三氧化二铝的测定试验

Determination of Al_2O_3 Content of Scale Deposit by Complexometric Titration

间接络合滴定法测定污垢中三氧化二铝含量 ,操作过程繁、不易掌握。作者通过试验 ,选择了用直接络合滴定法 ,从而精简了操作程序、提高了准确度。

A new method used in determining Al 2O 3 content of scale deposit by direct complexometric titration is presented,it has advantages of high sensitivity,good repeatability,simplicity and rapidity for the analysis processes over the traditional one.
