Clinoptilolite is the silicon, aluminum, oxygen composed tetrahedra, wherein the silicon-oxygen tetrahedron and aluminum-oxygen tetrahedron consists the unlimited expanded three-dimensional structure.
In the tetrahedral structure of the clinoptilolite, the negative charge caused by the replacement from silicon ions to aluminum ions will be balanced by sodium ions, potassium ions, calcium ions and magnesium ions, which contributes to the strong adsorption and ion exchange capacity of zeolite.
Clinoptilolite is filled with pores and channels, which is much more complicated than the hive with 1 cubic micrometer having one million pores and channels. If compared clinoptilolite to the hotel, then there are one million rooms in this 1 cubic micrometer super hotel, and this hotel can automatically open the door or shut the door of the rooms according to different sex, height, weight, hobbies of the guests (molecules and ions), which will neither let the fat guest go to the room of the thin guest, nor the tall guest share the same room with the short guest, and makes clinoptilolite the unique role of molecular sieve.
With the unique structure, Clinoptilolite has big internal specific surface area , which makes it very strong adsorption capacity to ions. The channels of clinoptilolite shares the similar fixed size, which can adsorb those with smaller diameter, and exclude those with larger diameter which endows it the proprietary of selective adsorption to ions and molecules.
