随着人们对环境保护的重视,对水中痕量杂质元素的测定,已进行过许多工作。除美国试验和材料学会(ASTM)和环境保护局(EPA)出版的标准湿化学方法外,其它资料还报道了大量的不同测定技术,包括极谱、原子吸收光谱、中子活化、火花源质谱、比色法和X-荧光法。V.M.Leroy和A.J.Lincoln对化学光谱法测定水中的杂质作了简单介绍,并详细介绍了他们采用残渣盐重量比值法光谱分析工业排放废水的方法,但该法要取水样一升蒸干,操作麻烦又浪费时间。
As people pay more attention to environmental protection, much work has been done on the determination of trace impurities in water. In addition to the standard wet chemistry methods published by the American Society for Testing and Materials (ASTM) and the Environmental Protection Agency (EPA), a variety of different assay techniques are reported, including polarography, atomic absorption spectroscopy, neutron activation, spark source mass spectrometry , Colorimetric and X-fluorescence methods. VMLeroy and AJLincoln briefly introduced the method for the determination of impurities in water by chemical spectrometry and introduced their method for the spectral analysis of industrial waste water by the residue weight ratio method. However, this method requires one liter of water sample to be evaporated and the operation is troublesome Another waste of time.
