In this study the effectiveness of sorption Basic Violet 10 were examined (the popular in the industry cationic dye), on 6 different non-conventional sorbents: chitin, sawdust, compost, silage corn, zeolite and fly ash. For each test sorbent was determined optimum pH of sorption. Was also a designated the maximum sorption capacity with respect to the Basic Violet 10. The results obtained were analyzed with the use of three sorption isotherms: Freundlich, Langmuir and double Langmuir. Among the organic sorbents tested, the highest capacity relative to Basic Violet 10 shown sawdust (Q_max = 156.5 mg/g) and corn silage (Q_max = 180.8 mg/g). In the case of mineral sorbents such as zeolite or fly ash, the maximum absorptive capacity Basic Violet 10 was respectively Q_max = 144.1 mg/g and 170.1 mg/g.
