Clinoptolite refers to the aluminum silicate mineral containing sodium, potassium, and calcium in the zeolite family, with crystals mostly in the form of transparent plates. Zeolite is one of the most abundant zeolite minerals. Its crystal is transparent and can also turn brown or red due to impurities. Zeolite is a hydrated alkali metal aluminosilicate that can function as a molecular sieve after dehydration, selectively extracting nitrogen from the air and enriching oxygen. Zeolite can also be used as an ion exchange agent for the treatment of nuclear waste, and it is also a filler and expansion agent in the papermaking industry.

Based on an annual production of approximately 3 million tons of natural zeolite worldwide, over 80% of the world’s zeolite production is composed of clinoptilolite type natural zeolite minerals. In addition to natural ones, many synthetic zeolites have been customized around the world for the development of cationic seconds. However, so far, only 232 synthetic zeolites with these structures have been discovered and synthesized, so many zeolite scientists question why only a small fraction of possibilities have been observed. Natural zeolite is a resource with abundant reserves, which is a crystalline hydrated aluminosilicate with a skeletal structure, containing pores occupied by water, alkali, and alkaline earth metal cations. Due to their high cationic ability and the characteristics of molecular sieves, natural zeolites have been widely used as adsorbents for cations in separation and clean workbenches over the past few decades.

The clinoptilolite series includes three species. Clinoptilolite K, clinoptilolite Na, and clinoptilolite Ca are named after their main elements. These elements are exchanged during cation exchange, which is beneficial for heavy metals, toxins, ammonia, etc. that have higher attraction to minerals.

The exchange capacity of NH4 cations in clinoptilolite rocks is relatively high, and clinoptilolite can also selectively exchange certain heavy metals, making it suitable for removing heavy metal ions.

1. Adsorption performance. Zeolite has a large specific surface area (500-1000 square meters/gram) and can generate significant diffusion force, making it an excellent adsorbent. There are many uniformly sized pores and channels inside zeolite crystals, which have precise and fixed diameters (about 3-11A) under certain physical and chemical conditions. Substances smaller than this diameter can be adsorbed by them, while substances larger than this diameter are excluded. This phenomenon is called “molecular sieve” effect, but not all zeolites can act as molecular sieves.

2. Catalytic performance. Due to its large adsorption surface, zeolite can accommodate a considerable amount of adsorbed substances, which can promote chemical reactions on its surface. Therefore, zeolite serves as an effective catalyst and catalytic carrier.

3. Thermal stability. The thermal stability of zeolite rock is related to factors such as the type of cations contained in zeolite rock, the silicon aluminum ratio of zeolite, and the internal structure of zeolite.

4. Acid resistance. Zeolite has good acid resistance. In addition, zeolite also possesses process properties such as chemical reactivity, far-infrared radiation, and reversible dehydration
