摘要
建立了邻苯二甲醛含量的化学分析测定方法,并采用t检验法进行显著性检验。结果表明,样品平均回收率(n=5)为99.82%,RSD为1.29%,t值均小于t表值(2.776),方法准确、可靠、重现性好,与气相色谱法无显著性差异,适用于芳醛的常量分析,能够满足邻苯二甲醛生产中监控分析的需要。
The content of o-phthalaldehyde chemical analysis method was established and t-test for significance test was used.The results showed that the average recoveries of sample were 99.82% with corresponding RSD of 1.29%,and the t values were all less than 2.776.This method was proved to be accurate,reliable,reproducible.The results of determination was compared with gas chromatography,with no obvisous difference.It was suitable for the determination of the constant analysis of aromatic aldehydes and the production control analysis of o-phthalaldehyde.
