Gemini surfactant is a kind of surfactants with special molecular structure. Its molecule is composed of the ionic head group of the two surfactants linked by the spacer through chemical bond. Because of its special structure, it has a special microstructure; it has a special use, can be used for the synthesis of mesoporous structure template, special chemical separation, etc.; for the Gemini surfactants which connect two different surfactant monomers on the head group, recent research shows that it has two kinds of surfactant properties.

Scholars at home and abroad have carried out a lot of meaningful research and exploration in the remediation of PAH contaminated soil by surfactants. However, the existing researches mainly focus on the traditional surfactants, which are often toxic, secondary pollution and high price. Therefore, the search for new economic, effective and environmental friendly surfactants will become the research hotspot and focus in the future.

New gemini surfactants and biosurfactants are widely concerned because of their high efficiency and environmental friendliness. The solubilization efficiency of Gemini surfactants and biosurfactants is higher than that of traditional surfactants.

Surfactant enhanced remediation technology has become a potential remediation technology for organic soil pollution. It mainly uses the solubilization effect of surfactant solution on hydrophobic organic pollutants to promote the desorption and dissolution of organic pollutants adsorbed on soil particles, and finally move out of the soil environment, so that the soil can be repaired. In the technology of bioremediation of polluted soil, if necessary, adding a proper amount of surfactant can disperse and promote the growth of microorganisms.
