Zeolite molecular sieves balling _ new (certified) _ new zeolite molecular sieves 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 Cr (VI) simulated waste (pH = 6.5) sieve Forum centrifuge tube, add 0.1g of modified zeolite, 40 ℃ temperature oscillation after a certain time, centrifuged, washed changes in the value of content by atomic absorption 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, the upper layer was measured by atomic absorption spectrophotometer supernatant Cr (VI) content value changes. Recently, the Shanghai Medical Devices Medical Devices Engineering College researchers published papers - Shanghai new titanium zeolite molecular sieve, sieve PSA aims to take advantage of differences in the molecular sieve oxygen and nitrogen adsorption capacity and adsorption capacity of the adsorption pressure changes with change features produced in the medical, health for the purpose of medical oxygen, with a clean, easy access and so on. Is simple and convenient to obtain breathing oxygen using molecular sieve pressure swing adsorption principle designed a miniature medical oxygen equipment.
