Β-Siklodekstrin Bazlı Kompozitin Sentezi Ve Katyonik Boya Gideriminde Kullanımı

Abstract

The aim of this study is synthesis of β-cyclodextrin based composite and using it for cationic dye removel. The adsorption experiments were carried out under the appropriate conditions using the bath method. For characterization of composite, spectra of composite before and after dye removel were analyzed by fouirer transform infrared spectrophotometer (FTIR). Some parameters such as effect of contact time, initial dye concentration, temperature and pH have been investigated. The optimum pH has been found as 8 for adsorption (experimental conditions: initial dye concentration (Co):100 mg/L, temperature (T):25 oC, agitation speed (r):140 rpm, amount of adsorbent: 10 mg, volume of dye solution (V):50 mL). For pH experimental conditions, 6 different dye solutions at pH:3,4,5,6,7 and 8 were used. Adsorption experiments indicated that the adsorption capacity was dependent of operating variables and the process was pH-dependent. Besides, adsorption mechanism has been evaluated by pseudo-first and pseudo-second kinetic models. According to the results obtained from the experimental data, pseudo-second-order kinetic model has been found to be more compatible (because the correlation numbers are larger (R2>0.99) than pseudo-first-order kinetic model. The highest adsorption capacity has been determined as 240.12 mg/g from the data obtained (Co:300 mg/L, T:25 oC, r:140 rpm). In conclusion, it can be said that the synthesized composite material is a suitable material for cationic dye removal due to its good adsorption capacity
