 The study examined the effect of synthesis mode and alkali concentration on the formation of zeolites from coal fly ash. The results showed that the crystal structure of sodalite was dominant and all samples produced. The specific surface area of the samples was measured using the BT method and the results indicated that the zeolite materials had high surface areas. The absorption of heavy metals such as nickel, cadmium, and lead onto the zeolite materials was studied using the Langmuir and Freundlich models. The results suggested that the zeolite materials could be used as an effective and low-cost alternative for the production of its sorbents. This article was authored by Hannah Koshleck.
