Water solubility enhancements of PAHs by sodium castor oil sulfonate microemulsions

Water solubility enhancements of naphthalene( Naph), phenantherene(Phen) and pyrene(Py) in sodium castor oil sulfonate(SCOS) microemulsions were evaluated. The apparent solubilities of PAHs are linearly propertional to the concentrations of SCOS microemulsion, and the enhancement extent by SCOS solutions is greater than that by ordinary surfactants on the basis of weight solubilization ratio(WSR). ThelogKcm values of Naph, Phen, and Py are 3.13, 4.44 and 5.01 respectively, which are about the same as the logKow values. At 5000 mg/L of SCOS conccentration, the apparent solubilities are 8.80, 121, and 674 times as the intrinsic solubilities for Naph, Phen, and Py. The effects of inorganic ions and temperature on the solubilization of solutes are also investigated. The solubilization is improved with a moderate addition of Ca^2 , Na^ , NH4^ and the mixture of Na^ , K^ , Ca^2 , Mg^2 and NH4^ . WSR values are enhanced by 22.0% for Naph,23.4% for Phen, and 24.6% for Py with temperature increasing by 5~C. The results indicated that SCOS microemulsions improve the performance of the surfactant-enhanced remediation(SER) of soil, by increasing solubilities of organic pollutants and reducing the level of surfactant pollution and remediation expenses.

Preparation of PFS coagulant by sectionalized reactor

The oxidation rate of ferrous sulfate is investigated for the preparation of polyferric sulfate(PFS)coagulant.In is proved that this reaction is zero order with respect to Fe^2 ,first order with respect to NO2(g),and first order with respect to the interface area between gas phase and liquid phase.According to this mechanism,sectionalized reactor(SR) is used in place of traditional reactor(TR),and the liquid of reaction mixture is recycled by pump.As a result,not only the flow path of reaction liquid is prolonged,but also gas-liquid contact area enlarged,and the reaction distinctly accelerated,compared with traditional reactor.The effects of parameters including temperature,acidity and others on the reaction rate are also discussed.
