毒死蜱等危险农药的溶解度数据对于确定其从土壤中的残留毒性和了解其控制释放特性是重要的。本文用气相色谱法测定了298.15、303.15和308.15K下毒死蜱在纯水、甲醇和水-甲醇混合物中的溶解度。结果表明，毒死蜱在甲醇中的溶解度高于在水中的溶解度。在水中加入甲醇可以提高毒死蜱在水中的溶解度。当混合物中甲醇含量较高时，观察到温度对毒死蜱溶解度的影响。
Solubility data of a hazardous pesticide like chlorpyrifos are important in order to determine its residual toxicity from soil and to understand its controlled release characteristics. In this paper, solubility of chlorpyrifos was measured by using gas chromatography in pure water, methanol, and water–methanol mixtures at 298.15, 303.15, and 308.15K. The results indicate that chlorpyrifos is more soluble in methanol than in water. The solubility of chlorpyrifos in water can be enhanced by adding methanol to water. The effect of temperature on the solubility of chlorpyrifos was observed at higher methanol content in the mixture.
