【 摘 要 】

The adsorption of cationic dye methylene blue on natural and Fe-modified materials obtaining two methods was investigated. It was established that adsorptive capacity of natural and Fe-modified materials depends on their cation-exchange capacity. It was determined that the adsorption capacity of Fe-modified materials with respect to the dye "methylene blue" in aqueous solution depends on the method of obtaining. The adsorption of methylene blue on sorbents describes by Langmuir model (the correlation coefficients are 0.9858-1.0000), which corresponds to monolayer adsorption on a homogeneous surface.
