dc.description.abstract |
Clay and clay minerals have always been used since the ancient times for making ceramic
materials and also as a building material. Over the past decades, there has been a growing
trend in their applicability in different areas such as industries, environmental remediation
and water treatment sectors. The growing trend is mainly associated with the fact that
they are chemically and mechanically stable, have higher specific surface area and cation
exchange capacity. Furthermore, clays can be modified to improve their functionalities in
different sectors. In this chapter, we present a review of the structural, mineralogical and
chemical properties of clay and the effect of surface modification in their structures. We
further looked at their applicability in arsenic and fluoride removal in their raw and also
in their modified form. Although the literature showed that modified clay minerals yields
higher adsorption capacity as compared to raw clays little nothing has been reported yet in
relation to the cost of modifying clays with chemical species. As such new studies should
also elaborate on the cost effectiveness of modifying clay minerals with chemical species. |
