原始语种摘要: Cloud point extraction (CPE) is carried out to extract chrysoidine dye from aqueous solution using two different non-ionic surfactants, TX-100 and TX-114. The effects of different operating parameters, e.g., concentrations of surfactant, dye and salt, temperature, pH on extraction of both dye and surfactant have been studied in detail. The extraction of dye increases with temperature, surfactant concentration and salt concentration. Various design parameters of a CPE process have been estimated by developing correlations for dye solubilization and fractional coacervate phase volume with the operating conditions. The equilibrium solubilization data at four different temperatures follow Langmuir type isotherm. A method is presented to calculate the feed surfactant concentration required for...
