Textile dye removal from aqueous solution using Metakaolin as adsorbent

In this study adsorption capacity of metakaolin was investigated through removal of textile dye fromaqueous solution. For this purpose, kaolin was dehydroxylated via endothermic process at 600 ºC. Theobtained metakaolin was characterized by particle size analysis (PLS) to determine average particle size.The effect of adsorbent dosage on removal efficiency was studied. Different dosage from 1 to 20 g/l wasapplied for adsorption process. The results showed that 5 g/l is the best dosage of metakaolin. At the sameadsorbent concentration metakaolin shows higher adsorption capacity than raw kaolin.
