| Abstract: | Relations between preparation of mixed solution containing Bi3 ＋ , Pb2＋ and testing results were studied. During Bi （ NO3 ） 3 dissolving, the quantity of HNO3 was determined. Sodium Sulfide and CTMAB are used as pre- cipitate to deal with the waste liquid after the continuous determination of Bi3＋ and Pb2＋ in which complexion is used. The precipitation was dissolved by HNO3 and then was used as a sample for the students＇ experiment repeat- edly. The adoption of this method has made the green chemistry experiment possible. |
