What are the applications of silicone foam strips

The application of functional silica gel carrier material in environmental science is mainly reflected in its separation, adsorption and concentration of trace pollutants in the environment, such as heavy metals, pesticide residues or toxic compounds in aqueous solution. Because the content of polluting compounds in most environments is low and miscellaneous, which leads to many interfering substances, in which aspects are silica gel foam strips applied?

1. Application in Environmental Science

Functional silica gel strips are widely used as adsorbents in environmental science to remove heavy metal ions from wastewater. This is because compared with other adsorbents, silica gel functional materials not only have functional groups cooperating with heavy metals, but also have good chemical stability under certain strong acid and alkali conditions. At the same time, they also have the characteristics of easy separation from solution and high reusability in the process of treatment. Different functional ligand silica gel is used as a carrier for the adsorption of different metals, and each functional group has corresponding advantages and disadvantages. The reasonable application of different ligand functional silica gel can make it an ideal adsorbent for heavy metals.

2. Application in Separation Science

Functionalized silica gel strip can be used as stationary phase and is often used in chromatographic separation. It has high stability in various mobile phases. In the application of separation and analysis, the chromatographic column made by using it as the stationary phase has high column efficiency, good reproducibility and long service cycle, and can be used for gradient elution. Because the functional bonded stationary phase is stable, it is not easy to lose in the application process, and has a wide range of application, it shows good selectivity for almost different types of compounds. In recent years, the functional silica gel has been used as the stationary phase in chromatographic separation, which has gradually replaced the liquid-liquid distribution chromatographic separation method, It has been widely used and occupies an extremely important position in the science of efficient separation.

Because the functional silica gel foam strip has superior adsorption for metal ions, and most metal ions (such as platinum, rhodium, palladium, etc.) have strong catalytic activity, the functional silica gel can be used to support metal catalysts to catalyze organic synthesis reactions. Usually, the functional silica gel carrier with strong affinity for metals is used as the support, and the complex cooperation between ligands and metals is used to support heavy metal catalysts to make heterogeneous catalysts for organic synthesis reactions.
