Odstranění chromu s oxidačním číslem VI z vodného prostředí pomocí směsi šišek v kontinuálním průtočném systému

Abstract

The theoretical part of the thesis is described biosorption in a continuous flow system and its mechanisms to remove Cr (VI) with a mixture of cones. There, the basic issue biosorption, its use, process chemical reaction taking place. Furthermore, the work deals with the description of kinetic models in dynamic systems using models Thomas, Yoon-Nelson model and BDST model. The work is focused on using biosorbents, namely a mixture of cones. Describes the behavior and properties of chromium in an aqueous medium. Results from the experimental part are shown graphically.Using kinetic models of dynamic systems, it was found that the best efficiency of removal of Cr (VI) was achieved using column height of 10 cm, that was a 31 g biosorbents and ideal flow velocity of the solution of metal ions is at a rate of 10 ml min- 1.Účinnost biosorbents was 78.75%.
