Alkali-Activated Cements as Immobilisation Matrices for Arsenic Wastes

The paper reports on a study of the leaching characteristics of alkali-activated pulverized fuel ash (PFA) geopolymers containing arsenic (As) and morphological and compositional development. Described are the results of some of the leaching and microstructural studies on alkali-activated fly ash matrices that contain arsenic with additional iron and manganese. Arsenic leaching from fly ash is high, and increased considerably by the presence of manganese.
