| Abstract: | Trace cadmium in the sodium salt reagents of NaBO2. 4H2O,NaOAc,Na2CO3 and Na2HPO4l2HzO was determined by flame atomic absorption after separating and enriching with surmydryl cot-ton. The method is convenient and quick,and the refative standard deviatiions of the determination isless than 4. 61 %. |
