摘 要:运用常量重量法测定了有机锡化合物锡的含量,确定了分析条件和过程.对不同类型有机锡化合物含量的分析结果表明,该方法易于操作,简便快速,结果准确,重现性好.The gravimetric method was studied for the analysis of tin content in organotic compounds, Analytic conditions and process were carefully investigated. 0. 1000-0. 20009 of sample was decomposed with 2-3 drops of concentrated H2SO4 and HNO3(Volume 1: 1), The excessive acid was evapovated directly on a low flame, the residuewas ignited at 900℃ for 2h, finally formed is SnO2 and weighed. The adventage of thedeveloped method are simple, rapid high accuracy and good reproducibity.
