摘要

含有大量重金属的工业废水排放到环境中,对环境造成了巨大破坏,采用基于原子吸收光谱的工业废水重金属含量测定方法,对工业废水中含有的重金属Cu、Cr、Ag、Pb、Ni的含量进行测定,首先进行重金属标准溶液配制,给出其测定结果,根据各重金属标准溶液测定方法,按照相同的仪器工作条件进行工业废水重金属水样测定,测定结果显示,除了Ni以外,其他重金属浓度含量都超过国家所规定的最高排放量,与其他传统测定方法相比,基于原子吸收光谱的工业废水重金属含量测定方法测定所需时间较短,测定的准确度较高。
        Industrial wastewater containing a lot of heavy metals is discharged into the environment, causing great damage to the environment. The industry based on atomic absorption spectroscopy is used. The method for determining the heavy metal content of wastewater is determined by measuring the contents of heavy metals Cu, Cr, Ag, Pb and Ni contained in industrial wastewater, first preparing a heavy metal standard solution, and giving the measurement result, according to the determination method of each heavy metal standard solution, according to the same The working conditions of the instrument are used to measure the heavy metal water in industrial wastewater. The results show that the concentration of other heavy metals in addition to Ni exceeds the maximum emission specified by the state. Compared with other traditional methods, heavy metal of industrial wastewater based on atomic absorption spectroscopy. The content determination method requires a shorter time and a higher accuracy of the measurement.
