Abstract
Composite hydrogels (CH) on the basis of acrylic acid (AAc) and acrylamide (AA) with bentonite clay (BC) have been obtained. Kinetics of swelling of obtained CH in water were investigated and it was shown that it has a good swelling degree which was depended on the content of BC in CH. Sorption of methylene blue (MB) by gels from water solutions was investigated by static method. It was determined that the sorption ability of CH was higher as compare to the gels obtained without addition of BC. Influence of temperature on the sorption of MB from solutions was also investigated, which showed increased sorption of MB with rising the temperature of the medium. On the basis of obtained data, the changes of values of some thermodynamic parameters of the sorption process were calculated.
