Generally, porous material adsorption devices such as activated carbon/clay/ceramics are used for particle adsorption.
Ion adsorption, generally using anion or cation resin adsorption.
For odor adsorption, activated carbon is generally used.
After the adsorption operation, the adsorption column needs to be regenerated, that is, when the adsorption device reaches saturation, the specially designed organic solvent/inorganic solvent is used for cleaning and recycling, and the washed eluent contains solid particles or colloids, so it is necessary to regenerate the organic solvent by distillation separation.
