Investigation of Swelling, Adsorption and Mechanical Properties of Sodium Acrylate Based Hydrogel and Cryogels

In this study, swelling behavior (swelling capacity, equilibrium swelling ratio and swelling kinetics), basic dye (methylene blue) adsorption and mechanical properties of sodium acrylate based hydrogel and cryogels were comparatively investigated. Kinetic parameters were determined using linear and non-linear methods. In addition, the surface morphologies of cryogel and hydrogel structures were characterized using by Scanning Electron Microscopy (SEM). All results obtained from analyses were comparatively evaluated.

Sodyum Akrilat Esaslý Hidrojel ve Kriyojellerin Þiþme, Adsorpsiyon ve Mekanik Özelliklerinin Ýncelenmesi

Bu çalýþmada, sodyum akrilat esaslý hidrojel ve kriyojellerin þiþme davranýþlarý (þiþme kapasitesi, denge þiþme deðeri ve þiþme kinetiði), boyar madde (metilen mavisi) adsorpsiyonu ve mekanik özellikleri karþýlaþtýrmalý olarak incelenmiþtir. Kinetik paramatreler, doðrusal ve doðrusal olmayan metotlar kullanýlarak belirlenmiþtir. Buna ek olarak, kriyojel ve hidrojel yapýlarýn yüzey morfolojileri, taramalý elektron mikroskobu (SEM) kullanýlarak karakterize edilmiþtir. Analizlerden elde edilen tüm sonuçlar karþýlaþtýrmalý olarak deðerlendirilmiþtir.
