Abstract

The wastewater of textile industry, emitted into the environment at different pH, consists of a wide range of

organic materials, heavy metals, dissolved salts, coloring, blur and and require first degree treatment. It has

long been known that clays have adsorbed dyestuffs and heavy metals and therefore clays have been used for

the removal of pollutants as adsorbents in recent years. Clays can be accessible easily and cheaply, therefore

their use for the removal of dyestuff is economically attractive. In this study the capacity of clays used for the

removal of dyestuff has been investigated. As clay, the natural clay taken from Derik province of Mardin city

(Turkey) and samples of montmorillonite clay taken from southern Clay Products Company have been used

and a dyestuff Methylene Blue removal has been studied. BET analysis for the determination of pore

dimensions of clays and XRF analysis for the determination of materials found in the composition have been

used in our study. The adsorption of dyestuff Methylene Blue, which is used in our study, on natural clay and

commercial clay has been evaluated graphically for 50 mg/L initial dyestuff concentration at three different

temperatures of 25o C, 35o C and 45o C and and their thermodynamic parameters have been investigated.
