Název v původním jazyce

Removal of basic (Methylene Blue) and acid (Egacid Orange) dyes from waters by sorption on chemically treated wood shawings

Popis výsledku v původním jazyce

Spruce wood shavings from Picea abies were used for an adsorptive removal of both basic as well as acid dyes from waters. The sorption properties of the sorbents were modified with HCl, Na2CO3 and Na2HPO4. Although the chemical pretreatment does not alter substantially the structure of wood, it modifies a surface chemistry of the sorbent (acid-base properties), and consequently its sorption ability towards ionic species. The treatment of the wood sorbents with alkaline carbonate solution as well as withphosphate solution increased the sorption ability for the basic dye (Methylene Blue), whereas the treatment with mineral acid decreased the sorption ability for Methylene Blue to some extent. The opposite is true for the sorption of the acid dye - Egacid Orange. The maximum sorption capacities estimated from the Langmuir-Freundlich isotherms ranged from 0.060 to 0.165 mmol g-1 for the sorption of Methylene Blue, and from 0.045 to 0.513 mmol g-1 for the sorption of Egacid Orange.
