最近日本“国家工程师”有限公司开始出售一种合成分子筛“ゼォリ—トM”。这种分子筛是化学合成的高纯度的分子筛,有效口径7～8(?)。化学式为Na_2O·Al_2O_3·10SiO_2·nH_2O。其特点是含SiO_2多,耐酸性、耐碱性显著高于A型、X型、Y型等分子筛。这种分子筛的Na~+能够随着酸同H~+交换,并且还容易同金属离子进行离子交换。利用这种分子筛的这些性质,不仅可以用作吸
Recently, Japan “National Engineers” started selling a synthetic molecular sieve “ゼ ォ リ - Suites M ”. This molecular sieve is chemically synthesized high-purity molecular sieve, effective caliber 7 ~ 8 (?). The chemical formula is Na 2 O · Al 2 O 3 · 10SiO 2 · nH 2 O. It is characterized by containing more than SiO2, acid resistance, alkali resistance was significantly higher than the A, X, Y-type molecular sieve. The Na ~ + of this molecular sieve can exchange with H ~ + with acid and is also easy to ion exchange with metal ions. Using these properties of this molecular sieve, not only can be used as a suction
