Activated molecular sieve, there is a new molecular sieve (certified), there is a new molecular sieve zeolite by Shanghai Limited. Shanghai new molecular sieve Limited (www.molsionms.com) is specialized in the "sieve" of the enterprise, the company of "honesty, hard service" concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: Mr. Pan. Shanghai Co., Ltd. of 10mL new molecular sieve containing a certain concentration of Cr (VI) simulated waste liquid (pH = 6.5) in a centrifuge tube, was added 0.1g modified molecular sieve, 40 ℃ temperature oscillation after a certain time, centrifugation, by atomic absorption changes in the value of the content of the supernatant Cr (VI) in the spectrophotometer. 60 ℃ vacuum drying 10h, to give a modified zeolite. A certain concentration of 10mL containing Cr (VI) analog waste (pH = 6.5) in a centrifuge tube molecular sieves, was added 0.1g modified molecular sieve, 40 ℃ temperature oscillation after a certain time, centrifuged standard sieve, using the atomic absorption spectrophotometer Determination of changes in the value of the supernatant Cr (VI) in. China Quality News Network news is a kind of aluminosilicate zeolite molecular sieve compound cubic lattice model, widely used in the chemical, electronics, petrochemical and natural gas industries. In order to monitor the quality of products in Dalian zeolite molecular sieves companies, and promote the healthy development of related industries, Dalian Municipal Quality Supervision Bureau in the city zeolite production enterprises supervision. The total sample of seven companies, products, seven batches, the test, sample pass rate of 100%.
