Abstract

It is environmentally, technically and commercially important to purify aqueous media which are polluted by

dyes. Conventional biological and chemical refinement technologies are used in drain water treatment. Even if

the utilization of adsorbents for increasing the quality of treated water is already known, due to an abrupt

increase in number of pollutants and pollution doses the need for new treatment technologies and reusable

adsorbents has increased. It is known for a long time that active carbon adsorbs colourants and heavy metals

and thus, it has been being used as adsorbaent to get rid of these pollutants from water recently. In this study,

the capacity of active carbon in removal of colourant was investigated. Zivzik pomegranate from Siirt district

of TURKEY was used as active carbon and it was prepared with ZnCl2 by chemical activation. Since

measurement of surface area determines amount of colourant it can remove, surface area was measured by BET

and removals of Methylene Blue and Crystal Violet were investigated. In our study, adsorptions to active

carbon at 45°C for the colourants of Methylene Blue and Crystal Violet were evaluated for four different initial

colourant concentrations of 200, 400, 600 and 800 mg/L graphically and isotherm parameters of Langmuir,

Freundlich, Temkin ve D-R were investigated. It was found in, this study, that adsorption of both colourants

obey to Langmuir isothermal model.
