WebIon Exchange as a Sorption Process • Since ion exchange occurs between a solution and the internal surface of a solid it can be viewed as a special type of sorption process • There are many similarities between adsorption and ion exchange. The two processes are often analyzed using similar models • Unlike adsorption ion exchange requires an Webionised substances by ion exchange. Ions The soluble, ionised substances are present in water as ions, which are electrically charged atoms or molecules. The positively …
