Abstract
Humic add occurs in waters naturally. Humic add gives its characteristic yellowish to brownish colour to water making it unaesthetic. In this study, synthetic hydrotalcite, hydrotalcite-like compounds, calcined hydrotalcites and modified forms of Montmorillonite were used to remove humic acid from water. The results indicated that surfactant treated Montmorillonite was more effective than other forms of modified Montmorillonite. In the case of hydrotalcites, hydrotalcite-like compounds removed more humic add than synthetic hydrotalcite. Surfactant created Montmorillonite, however, was found to be a better adsorbent when compared to other day samples.
