摘要
偏硼酸钠、无水乙酸钠、无水碳酸钠、磷酸氢二钠等试剂中的痕量镉，经巯基棉分离和富集后，以火焰原子吸收光谱法进行测定。方法会简便、快速。测定的相对标准偏差均小于4.61％。
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 %.
