Abstrakty

W pracy przedstawiono przegląd najnowszej literatury poświęconej porównaniu metod biologicznych, fizycznych i chemicznych stosowanych do usuwania syntetycznych barwników organicznych z roztworów wodnych. Szczególną uwagę zwrócono na zastosowanie w tym celu procesów adsorpcyjnych na węglach aktywnych. Skupiono się na analizie procesu adsorpcji barwników kationowych i anionowych na różnych materiałach węglowych, w tym na adsorbentach uzyskanych z prekursorów odpadowych. Przytoczono przykłady handlowych węgli aktywnych, które są stosowane do skutecznego usuwania barwników z roztworów wodnych. Podano parametry ich struktury porowatej, a także zdolności adsorpcyjne względem wybranych barwników. Opisano czynniki wpływające na proces adsorpcji barwników z roztworów wodnych (masa i rodzaj użytego adsorbentu, stężenie początkowe i klasa użytego barwnika, czas, intensywność mieszania, temperatura i pH roztworu). Na tej podstawie wykazano, że proces adsorpcji na węglach aktywnych jest jednym z najważniejszych sposobów skutecznego usuwania barwników z roztworów wodnych.

This work represents an overview of the newest literature on comparison of biological, physical and chemical methods applied to removal of synthetic organic dyes from water. A special attention is given to dye adsorption processes on activated carbons. The main focus is on the adsorption process of cationic and anionic dyes on different activated carbon materials, including adsorbents from waste precursors. Numerous examples of commercial activated carbons applied for effective removal of dyes from water solutions are presented. Parameters of their porous structure, as well as adsorption abilities of selected dyes are provided. Factors affecting the process of dye adsorption from water solutions are described (adsorbent mass and type, initial concentration and class of dye, adsorption time, mixing intensity, temperature and solution pH). In conclusion, it is demonstrated that the process of dye adsorption on activated carbons is one of the most important ways of effective dye removal from water solutions.
