生物材料中二氯苯醚菊酯的反相高效液相色谱分析方法研究

目的为了解决二氯苯醚菊酯中毒检验的问题及进一步开展研究工作，建立多种生物材料中二氯苯醚菊酯高效液相色谱分析方法。方法选用shim—pack，CLC—ODS（5μm）作色谱柱，甲醇：水：冰醋酸（90：10：1）为流动相，检测波长为274mm。用空白添加试验系统地考察提取，净化方法及高效液相色谱分析条件。用日本大耳兔进行急性染毒，取材对所建方法进行验证。结果采用所建方法，空白组织添加回收率在0．2～20μg／g的范围内均大于85％；工作曲线线性良好（r＝0．9998）；以信噪比≥3计，最低检测限为10ng／g组织；方法重现性良好（CV＜4．5％，n=3）；染毒兔各组织中的内源性杂质均不干扰二氯苯醚菊酯的检测。结论所建方法适用于检测多种生物材料中的二氯苯醚菊酯，方法灵敏、准确，可望用于二氯苯醚菊酯的中毒检验、代谢动力学及分析毒理学的研究。

Spectrographic determination of barium in biological material

Spectrochemical determination of barium (Ba 2335.₃ Å) in some fatal cases of barium poisoning, and recovery experiments, are reported with and without the use of beryllium (Be 2348.₆ Å) as internal standard (precision ±20%).     

Rapid determination of ethylene glycol in biological material

A rapid and simple modification of a gas chromatographic (AFID) method of ethylene glycol determination, based on derivation with n-butylboronic acid, was developed.     

Detection of captopress and novopassit in forensic chemical analysis of cadaveric material

A method for identification of captopress and novopassit in drugs and biological objects is suggested. These agents are isolated by 90% ethanol or chloroform mixture with isopropanol. 11 color tests and thin-layer chromatography are suggested for identification. The threshold level of captopress detection is 0.1 mg%, that of novopassit 5 mg%.     

A method for determining arsenic in biological material]

Method of extraction-atomic absorption detection of arsenic in biologic material using naphthenic acid was developed and tested. Method can be used for arsenic detection in postmortem material. It differs from the known method by its accuracy, reliability and simple use.
