  Determination of Dicofol in Various Environmental Samples by Spectrophotometric Method Using Chromogenic Reagent

  摘要：

  A sensitive spectrophotometric method for determination of dicofol in subparts per million levels is described, which is based on Fujiwara reaction. Dicofol on alkaline hydrolysis gives chloroform, which reacts with pyridine to produce red color. The color is discharged by addition of glacial acetic acid. The glutaconic aldehyde formed reacts with 4-aminoacetanilide to gave an orange-red dye which is extractable in 3-methyl-1-butanol. The extracted dye shows absorption maximum at 525nm. Beer's law is obeyed in the range of 0.025-0.25g mL(-1). Important analytical parameters such as time, temperature, reagent concentration, acidity etc. have been optimized for complete color reaction. Sandell's sensitivity and molar absorptivity for the system were found to be 0.000343g cm(-2) and 1.077 x 10(6) L mol(-1)cm(-1), respectively. The proposed method is satisfactorily applied to microlevel determination of dicofol in various environmental samples.

  spectrophotometric method for determination of trichloroethylene is proposed. Trichloroethylene is treated with pyridine to form glutaconic aldehyde by heterolytic cleavage of the pyridine ring. Glutaconic aldehyde is further coupled with 4-aminoacetanilide to form an orange–red dye which is extractable in 3-methyl-1-butanol. The extracted dye shows absorption maximum at 520 nm. The system obeys Beer’s

  提出了一种简单的灵敏萃取分光光度法测定三氯乙烯的方法。用吡啶处理三氯乙烯，通过吡啶环的杂合裂解形成戊二醛。戊二醛进一步与4-氨基乙酰苯胺偶联形成橙红色染料，可在3-甲基-1-丁醇中提取。提取的染料在520 nm处显示最大吸收。该系统在0.05–0.8μgmL -1的范围内遵守比尔定律。重要的分析参数（例如时间，温度，试剂浓度，酸度等）已经过优化，可实现完全的显色反应。发现该系统的Sandell灵敏度和摩尔吸收率分别为0.001μgcm -2和1.2×10 5  L mol -1  cm-1。所提出的方法可令人满意地应用于各种环境和生物样品中微量三氯乙烯的测定。
