用二硫腙比色法检测食品、水等样品的铅时，往往因二硫腙试剂本身的原因造成检验结果的系统分析误差。作者查阅有关资料进行分析，并提出相应解决办法。１二硫腙的性质二硫腙的结构式为Ｓ＝Ｃ／＼ＮＨ—ＮＨ—Ｃ６Ｈ５ＮＨ＝Ｎ—Ｃ６Ｈ５由二硫腙的结构式可见，其氮原子上...
With dithizone colorimetric detection of food, water and other samples of lead, often due to the dithizone reagent itself causes the systematic analysis of test results error. The author consults the relevant information for analysis and proposes corresponding solutions. 1 Dithizone Properties Dithizone structural formula for the S = C / NH-NH-C6H5NH = N-C6H5 dithizone structural formula can be seen on the nitrogen atom ...
