摘 要：A high Al-Si Chinese fly ash from Dou He power plant(Tangshan city,Hebei Province, Eastern China) was selected as starting material of the zeolitization *** material was obtained by conventional alkaline activation by using NaOH and KOH *** synthesis process was optimized by applying a wide ranges of reaction temperature,time and activation agent concentrations.A high solution / fly ash ratio was used in order to allow dissolution of highly resistant Al-Si phases such as *** synthesis yields were obtained by using both KOH and NaOH *** products reached a cation exchange capacity(CEC) up to 2.3 meq *** zeolites obtained with a high CEC were:NaP1,KM and F linde *** low contents of major impurities of this fly ash enhance the potential application for the synthesis of zeolites for waste water treatment.
