Natural zeolite is an emerging material that is widely used in industry, agriculture and defense, and its uses are still being developed. Zeolites are used as ion exchangers, adsorbent separators, desiccants, catalysts, and cement blending materials.

Zeolite is a water-bearing porous alkali metal or alkaline earth metal aluminosilicate mineral with a skeletal structure. It is widely available, has large reserves, and can be reused through recycling. Zeolite's unique structure, resource distribution and recyclability make it one of the most commonly used water treatment agents in wastewater treatment processes and is widely used for wastewater pollutants such as nitrogen, phosphorus, heavy metals and organic matter.

Zeolite itself has a multi-regular pore structure, and its pores are comparable to the molecular size of general substances, with a diameter of about 0.3~1nm, and its specific surface area is as high as 400~800m2/g. The special physical structure makes zeolite have two adsorption characteristics: selective adsorption and efficient adsorption.

Rapid hemostasis is essential for first aid in war wounds, and tourniquets have been the first choice for battlefield treatment. With the changes in battlefield injuries and the development of hemostasis concepts, emergency hemostasis techniques have changed from physical hemostasis to chemical and biological hemostasis, so scholars in the field at home and abroad have developed and applied a variety of new hemostatic materials and methods.

Molecular sieve is a class of adsorbent or film-like substance with uniform micropores, mainly composed of silicon, aluminum, oxygen and some other metal cations, whose pore size is comparable to the general molecular size, according to its effective pore size to sieve various fluid molecules.
