| Abstract: | The solubility of atrazine (solid) was measured in water + ethanol and water + propanol from 283.15 to 343.15 K. The experimental results showed that in ethanol + water and 1-propanol + water the solubility of atrazine increased slowly with temperature below 308.15 K but increased significantly above 308.15 K. It was also found that the slope of the solubility–temperature curve increases significantly with an increase in the mole fraction of organic solvent in the mixtures. The modified Apelblat and NRTL equations were applied to describe the measured systems. The model parameters of the NRTL equation were expressed as a function of temperature. |
