【摘要】 亚迪欣是一种新型蚕用消毒药剂,主要有效成分为三氯异氰尿酸、磷酸三钠。为加强该消毒药剂的生产质量管理,进行了产品的质量检测分析试验。药剂中三氯异氰尿酸的有效氯含量检测方法经对照试验、精密度及重复性试验,其相对标准差(RSD)分别为0.02%、0.10%及0.12%,且在0.418~2.338 mg/mL范围内线性关系良好,R2=1;加入磷酸三钠的平均回收率为100.1%、RSD=0.16%,说明加入磷酸三钠对三氯异氰尿酸的有效氯含量检测没有影响。磷酸三钠在密塞条件下放置24 h检测其含量基本不变,在干燥条件下的质量分数增加1.08%,在潮湿条件下的质量分数减少1.41%。试验结果显示对亚迪欣产品有效成分含量的检测方法及标准制订合理可靠,产品质量可控性强。更多还原

【Abstract】 Yadixin is a new high effective and wide-ranging disinfectant for silkworm rearing,and its main effective constituents are trichloroisocyanuric acid(TCCA) and trisodium phosphate(TSP).To strengthen the quality control during produce process,we carried out the quality test for the product in this paper.Determination method of the available chlorine content in TCCA was verified by tests of comparison,precision and repeatability,and RSD was 0.02%,0.10% and 0.12%,respectively.Linearity test result showed that there was a good linear relationship in the range of 0.418～2.338 mg/mL(R 2=1).Under condition of TSP,the average recovery of TCCA was 100.1% and RSD was 0.16%,indicated that TSP had no effect on determination of available chlorine content of TCCA.The content of TSP was determined under different storage conditions for 24 h.The results showed that TSP content almost was stable under the sealed condition,increased by 1.08% under the dry condition,but decreased by 1.41% under the wet condition.The above results showed that determination method and standard formulation for Yadixin is reasonable,and the method for quality control is feasible.更多还原
