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.
像毒死蜱这样的有害农药的溶解度数据对于确定其在土壤中的残留毒性以及了解其控释特性非常重要。本文通过气相色谱法在298.15K、303.15K和308.15K下测定了毒死蜱在纯水、甲醇以及水 - 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。向水中添加甲醇可以提高毒死蜱在水中的溶解度。在混合物中甲醇含量较高时观察到了温度对毒死蜱溶解度的影响。
