| 摘 要： | 采用标准分析方法,分别测定了ND—903中的三乙膦酸铝和百菌清的含量,并进行了热贮稳定性的研究。试验结果表明,采用碘量法和气相色谱法分别测定ND—903中有效成分含量的分析方法可行。准确度(99.4％～101.4％)和精确度(S_x=0.36,CV=0.44％)符合要求,ND—903中两种主要有效成分热稳定性较高,相对分解率2.79％。与其组成的单剂相对分解率(三乙膦酸铝1.06％,百菌清0.44％)差异不显著。ND—903热贮前后悬浮率分别是82.6％和76.9％

| Abstract: | The standard methods were used for determination of phosethyl -Al and chlorolhalonil h ND -903 and stability by heating storage, respectively. The results showed that two methods. were feasible for determination of a. i in ND- 903 by iodimetry and gas chromatography. The accuracy ranged 99. 4-101. 4%and precision was Sx 0. 36 and CVO 0. 44% accorded with the demands. Stability of ND-903 By heating storage was higher. The relative rates of dissolution of ND-903, phosethyl - Al and chlorothalonil were 2. 79% , 1. 06% and 0.44% , respectine ly . It's not different significantly from individuals. Suspensibility of ND-903 was 82. 6% , and after accelerated storage by heating was 76. 9%. |
