Nax molecular sieve is a commonly used molecular sieve with good adsorption performance and ion exchange performance. Here are some common types of NAX-type zeolite:1NAX-A molecular sieve: This kind of molecular sieve is mainly used to remove harmful substances such as organic matter and heavy metal ions in water, so it is widely used in the field of water treatment. 
2.NAX-B molecular sieve: NAX-B molecular sieve is mainly used to remove moisture, carbon dioxide and other harmful substances in gas, so it is widely used in gas drying, purification and other fields. 3.NAX-C molecular sieve: NAX-C molecular sieve is mainly used to remove sulfides, nitrogen oxides and other harmful substances in exhaust gas, so it can be used in waste gas treatment and environmental protection and other fields.
4.NAX-D molecular sieve: NAX-D molecular sieve is mainly used to remove anions in solution, such as chloride ions, sulfate ions, etc., so it is widely used in water treatment, chemical industry and other fields. 5.NAX-E molecular sieve: NAX-E molecular sieve has good ion exchange performance and adsorption performance, which can be used to remove heavy metal ions and organic matter in water, as well as in gas purification, environmental protection and other applications. 
In addition to the above common Nax-type molecular sieves, there are many other types of Nax-type molecular sieves, such as Nax-F type, Nax-G type, etc., and their application range is also expanding. With the development of science and technology, the performance and application fields of NAX molecular sieves will be further expanded and improved.
