Abstract：In order to prepare an in situ microemulsion suitable for the efficient solubilization of a variety of chlorinated hydrocarbon mixed pollutants in aquifers, this study used a mixture of chlorinated hydrocarbons such as PCE, CT, TCE and CF as the organic phase, and selected a mixture of sodium dodecyl sulfate (SDS), n-butanol and potassium chloride (KCl) as the precursor solution of microemulsion to construct an in situ microemulsion system. The effect of layer temperature and inorganic salt composition on the solubilization effect of in situ microemulsion was evaluated. The experimental results show that there is a quadratic function relationship between the concentration of n-butanol in microemulsion and the equivalent alkyl carbon number (EACN) of mixed chlorinated hydrocarbons, which can be used to determine the formulation parameters of the precursor liquid of microemulsion in the contaminated site of mixed chlorinated hydrocarbons. The solubility of chlorinated hydrocarbons in microemulsion can reach more than 500g/L,and the solubilization capacity is PCE>CT>TCE>CF. The viscosity of the precursor fluid was less than 2cp, and it had good migration performance in the underground environment. zeta potential was negative, which means it is not easy to be absorbed by a negatively charged medium. Temperature (10~20°C) has little effect on the solubilization of chlorinated hydrocarbons in microemulsion. The low concentration of chemical composition in water favored the dissolution of chlorinated hydrocarbons in microemulsion, and the order of influence of inorganic salt cations is Ca2+>Mg2+>K+>Na+.
