Streszczenie

In the presented study I have undertaken the research concerning the efficiency of dye removal which is crystal violet (the dye used for fabric dying and production of printing paste) from water solution with the use of activated carbons. In the research I have used fresh commercial active carbons WDex and WG-12. These carbons differ in their porous structure parameters (S, V, iodine, methylene and detergent values) as well as chemical properties of the surface (surface acidity, ability to dechlorine). It has been found that having the initial dye concentration 20 mg/L in the presence of activated carbons, the process of solution decolourisation takes place. Sorption capacity of activated carbon WDex equals 35 mg/g and in case of WG-12 – 12 mg/g. The sorption process of examined activated carbons is better described by Langmuir isotherm.
