Abstract

Syntheses of Molecular Sieve in Detergents with Kaolin Cao Mingli Pan Yahong Yuan JizuThe main technical conditions for synthesizing 4A zeolite with kaolin were determined. The whiteness and calcium ions exchange capacity (CIEC) of the product were increased by calcining and screening the coloring ions, and the high quality 4A zeolite was synthesized successfully. Moreover, the structure of 4A zeolite was studied by X ray Diffraction (XRD) and Fourier Transform Infrared (FTIR) spectroscopy, respectively.kaolin; calcine; 4A zeolite
