| 摘 要： | 在石化行业中，由于采气废水多为高舍盐废水，如果按照地表水、地下水的测试方法对其重金属指标进行测试，其测试结果和真实值之间存在较大的偏差。本研究中采用火焰原子吸收法对影响吸收的背景进行氘灯扣除，得到了一种适合于高含盐废水体中镉含量测定的分析方法。通过实验验证，该方法相对误差在8．75％以内，检测限0．0042mg／L，回...

| Abstract: | In petrochemical industry,the gas production wastewater usually contains high content of salt.It will disturb the determination of heavy metals resulting in a deviate from the real value if the determination adopting the method for ground water and surface water.In this paper,a novel determination method for cadmium was developed by adopting the Atomic Absorption Spectrometry to subtract the background through using the deuterium lamp,which was suitable to determine the cadmium content in high salt wastewat... |
