| 摘 要：介紹了一種準確簡(jiǎn)便的測定氯溴異氰尿酸煙劑中的有效成份的分析方法——碘量法。在烘干的碘量瓶中,先放入KI和氯溴異氰尿酸,然后迅速加入H2SO4水溶液,用標準Na2S2O3滴定至無(wú)色,以Na2S2O3的消耗體積折算出煙劑中的有效成分含量。此法準確,操作簡(jiǎn)單,花費少,空白煙劑無(wú)干擾,非常適用于生產(chǎn)廠(chǎng)家控制氯溴異氰尿酸產(chǎn)品質(zhì)量的要求。 |

| Abstract：Chlorobromoisocy anuric acid is the one that corrodes chromatographic column when analyzed with GC or HPLC.Iodimetry is a simple and accurate method that is used to measure active composition in chlorobromoisocy anuric acid smokes.In this method,H2SO4 solution was added quickly into the dry iodine amount bottle with KI and chlorobromoisocy anuric acid smokes,then titrated with the standard Na2S2O3 solution,the active ingredient content in the smoke was calculated from the cost volume of Na2S2O3.The method h... |
