火焰原子吸收光谱法连续测定化探样品中的银、铜、铅和锌

Determinations of Silver,Copper,Lead,Zinc in the Geochemistry Sample by FAAS

样品以氢氟酸、硝酸、高氯酸分解,制成HCl(1+9)溶液,在空气-乙炔火焰中,水相直接测定铜、锌,TOA-MIBK萃取,有机相中测定银、铅。

The sample resolves with the hydrofluoric acid,nitric acid,perchloric acid making into the HCl（1∶9） aqua,in the air-C2H2 flames,in the water phase,the copper,zinc were detacted simultaneously and directly,in the TOA-MIBK extraction phase,silver,lead were determined simultaneously.
