| Abstract: | Bath method is introduced to synthesize zeolitized diatomite. Sodium aluminate solution is prepared fi rst. Na-zeolite grows from diatomaceous skeleton by controlling the total alkali charge in the system, conditions such as reaction temperature. The surface of diatomite carriers has been in? uenced through degree of zeolitization.When the alkali charge is 47%, the surface area of the product reaches to 192m2/g. Character of samples is described by some methods suh as SEM, XRD, BET, BJH etc. |
