本法是将样品经碱处理,再用柱层析法获得纯品。通过红外光谱、元素分析等方法对其进行鉴定。用气液色谱法在2.5％XE-60/60-80目Chromosorb, W. AW DMCS柱上以内标法对其进行定量测定。 0—乙基—0,0—二(2,4二氯苯基)磷酸酯(以下简称EDDP)是近年来国外出现的一种高效低毒有机磷农药。我所与沈阳农药厂对此种化合物共同进行了研制。但分析方法国内外未见报道,为了满足科研和生产的需要,我们在第Ⅰ报的基础上开展了对EDDP的分析方法研究。现报告如下:
This method is the sample by alkali treatment, and then purified by column chromatography. Through infrared spectroscopy, elemental analysis and other methods to identify them. The compounds were quantified by gas chromatography on a 2.5% XE-60 / 60-80 Chromosorb, W. AW DMCS column using an internal standard method. 0-Ethyl-0,0-bis (2,4-dichlorophenyl) phosphate (hereinafter referred to as EDDP) is a kind of high efficiency and low toxicity organophosphorus pesticide which appears abroad in recent years. I and Shenyang Pesticide Factory jointly developed this compound. However, no analysis methods have been reported at home and abroad. In order to meet the needs of scientific research and production, we conducted an analysis of EDDP on the basis of the first report. The report is as follows:
