摘　　要：用火焰原子吸收法研究 p H值对黄河水中铜、锌离子含量的影响 ,结果表明 :p H值越低 ,水中金属离子含量越高。回收率在 94% - 10 4% ,相对标准偏差小于 2 %。The influence of pH on amount of Cu 2+ and Zn 2+ in the Huanghe river water was determined by flame atomic absorption spectrometry.The result indicated the lower of the pH,the more the amounts of Cu 2+ and Zn 2+ .The rate of recovery was between 94%～104%,the relative standard deviation was smaller than 2%.
