随着工业化的进程,在有色冶金、电镀、金属加工等部门三废中镍污染日渐严重,为检测环境、生物作品中镍含量,近年来原子吸收法为国内采用的主要方法,但此法在基层应用受到限制,其主要原因为仪器昂贵,使用条件严格,操作较复杂等。为克服上述不足,我们使用常用仪器,采用分光光度法对环境、植物和生物样品中镍含量进行检测,其结果与原子吸收法进行对比如下。

With the progress of industrialization, the nickel pollution in the three wastes of nonferrous metallurgy, electroplating, metal processing and other departments is increasingly serious. In order to detect the nickel content in the environment and biological works, the atomic absorption method has been adopted as the main method in China in recent years. However, Application is limited, the main reason for the expensive instruments, the use of strict conditions, the operation is more complex and so on. To overcome these shortcomings, we used conventional instruments to detect the nickel content of environmental, plant and biological samples by spectrophotometry. The results are compared with those obtained by atomic absorption spectrometry as follows.
