乙烯利重量法分析的改进

Improvement on the Gravimetric Analytical Method of Ethephon

对乙烯利重量法分析进行了重要改进。最佳试验温度为65℃,最佳干燥器尺寸为50mm×13mm(id.)。试验结果表明,本方法乙烯利在0.0774～0.6591g进样范围内和分解的乙烯呈线性,相关系数为0.9999。乙烯利重量法分析给出了较好的精密度,变异系数小于2%。

Important improvement on gravimetric analytical method of ethephon was carried out. Conditions of the analysis were as follows： optimal experimental temperature 65℃ and drier size 50 mm × 13 mm （id.）. This method was linear and reproducible over the range of 0.077 4 to 0.659 1 g analyte, between ethephon and the decomposing ethene. The coefficient was 0.999 9, and the variation coefficient was less than 2%.
