| Abstract: | The ion exchange ability and adsorption ability of zeolite from coal fly ash（CFA） are analysis according to its spatial structure. The review covers the synthesis technologies of zeolite with CFA including hydrothermal synthesis method, alkali fusion method, salt thermal synthesis method and mix alkali vapor deposition synthesis methods. The influence of kind of CFA, dosage and concentration of alkali, reaction temperature, and reaction time ete were summarized. Moreover, the application and development of modification technology for the zeolite from CFA was summarized. |
