Removal Mechanism of Light Non-aqueous Phase Liquid from Soil and Groundwater by Surfactant
表面活性剂去除土壤和地下水中LNAPLs作用机制研究

Surfactant increases solubilization of n-hexadecane and reduces interfacial tension between surfactant and n-hexadecane,which are very important for the removal of residual LNAPLs in porous media. After the solubilization of n-hexadecane and interfacial tension between Triton X-100 solution and n-hexadecane were studied through experiments,the forming rule of different states of n-hexadecane were analyzed through equilibrium washing experiment and sand pillar leaching experiment. The experimental results sh...
