硅胶为什么只吸附极性气体
就是这样.
就是这样.
Silica gel is a chemically inert,nontoxic,polar and dimensionally stable (< 400 °C) amorphous form of SiO2.After treatments it can have various pore size distributions on its surface.
Because of its hydrophilic,polar and other properties,silica is often used for drying of process air (e.g.oxygen,natural gas etc) and adsorption of higher (polar) hydrocarbons from natural gas.
