建立了用一种水溶性叶琳试荆同时分光光度测定痕量汞和铅的灵敏、简便的新方法.借助双波长技术和吸光度加和定律可用于味精及水分析,精密度及回收率令人满意,结果与电感耦合等离子体发射光谱法测定值一致.
A new sensitive and simple method for the simultaneous spectrophotometric determination of trace mercury and lead with a water-soluble Yehlin test was developed.With the aid of dual-wavelength technology and the law of addition of absorbance, it can be used for MSG and water analysis, precision and recovery People are satisfied with the results and inductively coupled plasma emission spectrometry measured values.
