Abstract
Solubility data of a hazardous pesticide like chlorpyrifos are important in order to determine its residual toxicity from soil and to understand its c ontrolled release characteristics. In this paper, solubility of chlorpyrifo s was measured by using gas chromatography in pure water, methanol, and wat er-methanol mixtures at 298.15, 303.15, and 308.15 K. 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 hig her methanol content in the mixture. (C) 2000 Elsevier Science B.V. All rig hts reserved.
