Abstract
In this study, hydrogels and clay composite polymeric gel were synthesized by using AAm monomer and clay, EGDM as a crosslinker and APS-TEMED as initiator-activator system. The swelling properties of the hydrogels, water absorption (swelling) and shrinking (deswelling) kinetics, the equilibrium swelling ratios in water were investigated. In distilled water, swelling kinetics at 25 °C, deswelling kinetics at 80 °C and swelling behaviour at different temperatures of synthesized hydrogels were determined by gravimetric methods. Then, their adsorption properties such as adsorption capacities and adsorption efficiency of synthesized hydrogel and clay composit polymeric gel were investigated in case of their usage in removal of Astrazon Yellow (AY), Astrazon Golden Yellow (AGY), basic Blue 3 (BB3) aqueous solutions at 25 °C. At equilibrium the swelling values and the diffusion coefficient of AAM based clay composit polymeric gel was determined to be significantly decreased compared to AAm based hydrogel. It was determined that adsorption capacity and removal percentage for three dyes of clay composit polymeric gel was higher
Özet
Bu çalışmada; Akrilamid monomeri ve kil ile çapraz bağlayıcı (EGDM), başlatıcı-hızlandırıcı sistemi (APS-TEMED) kullanılarak hidrojel ve kompozit polimerik jeller sentezlenmiştir. Hidrojellerin su absorpsiyon (şişme)- desoprsiyon (büzülme) kinetikleri, sudaki denge şişme değerleri ve sıcaklıkla denge şişme oranındaki değişim incelenmiştir. Sentezlenen jellerin destile su içinde 25 °C’de şişme kinetikleri, 80 °C’de büzülme kinetikleri gravimetrik metodla belirlenmiştir. Sentezlenen hidrojel ve kil polimer kompozit jelin 25 °C’de Astrazon Yellow (AY), Astrazon Golden Yellow (AGY) ve Bazik Blue 3 (BB3) boyar moddelerini içeren sulu çözeltiler kullanılarak, adsorpsiyon verimleri ve adsorpsiyon kapasiteleri gibi boyar madde giderim verimleri belirlenmiş ve bu sonuçlar birbirleri ile karşılaştırılmıştır
