在一般化學實驗室中,為了準確而簡捷地测定鈉離子。常應用醋酸鈾醯,但醋酸鈾醯是較為貴重的化合物,購置不易,故使用時必須盡量節省,而且應考慮到它們的回收及盡可能的重複使用。關於鈾化合物的回收方法,見諸文獻者,並不算多,由於所用原料及回收之產物不同,方法亦各殊異。如W Ja.Tartakowski自测定鈉的沉澱中將鈾轉變為 In general chemical laboratories, sodium ions are measured for accuracy and simplicity. Uranyl acetate is often used, but uranyl acetate is a relatively expensive compound. It is not easy to purchase. Therefore, it must be saved as much as possible, and its recycling and reuse should be considered as much as possible. As for the methods for recovering uranium compounds, there are not many people who read the literature. Because of the different raw materials used and the products recovered, the methods are also different. For example, W Ja.Tartakowski converted uranium into precipitate from sodium determination
