Shanghai has a new synthetic zeolite molecular sieve having Ltd design, good thermal stability and acid resistance, has become an important chemical products, such as used as adsorbents, catalysts and additives, such as washing, which is a molecular sieve 4A porous aluminosilicate containing crystal-like compounds were negative overall framework, easy and cation exchange interactions occur without disrupting the internal structure, with good selectivity cation adsorption characteristics, but the anion exchange capacity of adsorption and poor. 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 of modified zeolite molecular sieve type, 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) standard sieve in the centrifuge tube, was added 0.1g of modified zeolite molecular sieve, 40 ℃ temperature oscillation after a certain time, centrifuged, washed with atomic absorption spectrophotometer Determination of changes in the value of the supernatant Cr (VI) in. Jiangsu sieve, sieve, sieve by new Shanghai there are new molecular sieve Limited. Shanghai new molecular sieve Limited (www.molsionms.com) strong, credible, in Shanghai's Songjiang District elemental industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead the new molecular sieves, and you hand in hand into the brilliant, for a better future!
