Investigation of Sorption Activity of Brown Peat Moss Powder

Abstract

The present article investigates adsorption of cationic dyes methylene blue and Ni (II) ions on brown peat moss powder. Besides, the sorption activity of brown peat moss powder towards methylene blue was studied depending on dispersive capacity. It was established that adsorption of methylene blue on brown peat moss powder was increasing up to the particle size of 0.1 mm. Further decrease in the particle size did not result in the increase in brown peat moss powder sorption activity. It may be explained by degradation of plant tissue structures responsible for major sorption mechanism functioning. To identify the mechanisms of brown peat moss powder sorption, the anatomy and morphology organization as well as the IR-spectra of the initial brown peat moss powder samples and brown peat moss powder samples after Ni (II) sorption were studied.
