In recent years, with the acceleration of China's urbanization process and industrial transfer, there have been a large number of polycyclic aromatic contaminated sites caused by the closure and relocation of coking plants, coal-fired power plants and iron and steel plants. Among the soil remediation technologies in polluted sites, soil ectopic leaching technology has the characteristics of good effect, short cycle and low cost. It is widely used in practical site remediation. The key to the application of this technology is often to screen out environmentally friendly special surfactants for specific contaminated site soil, and use relevant physical strengthening and synergistic means to achieve efficient removal of pollutants.

Cyclodextrin is the general name of a series of cyclic oligosaccharides produced by amylose under the action of cyclodextrin glucosyltransferase produced by Bacillus. It is non-toxic and bio-friendly, and can be degraded and utilized by microorganisms in soil and natural water medium. Methyl beta cyclodextrin is a green synthetic alkylated derivative of beta cyclodextrin. Due to its hydrophilic outer edge, hydrophobic inner cavity and large water solubility (>20g/100g H2O, 25 ℃), it can form host guest inclusion complexes easily soluble in water with a variety of insoluble organics to increase the solubility of organic pollutants in the aqueous phase, Promote the release and migration of organic pollutants from soil particle phase to water phase.

Shandong Binzhou Zhiyuan Biotechnology Co., Ltd. has been specializing in the production of methyl beta cyclodextrin for more than ten years. It is also the first manufacturer in China to obtain the CDE registration number, registration number: F2021000272, feel free to connect us.
