Attapulgite is a clay mineral that has many applications, especially in agriculture and industry. It has not been studied extensively compared with other clay minerals for its sorption properties in environmental applications. In the present work the adsorption capacity of CTMA on attapulgite was found that was high and was mostly due to ion exchange mechanism. Furthermore, the experimental data fitted well to the Langmuir isotherm.展开更多
