چکیده مقاله
Polyacrylic acid/guar gum/Titanium dioxide PAA/GG/TiO2 hydrogels were fabricated according to the central composite design of response surface methodology by Design Expert software The results of methylene blue MB removal with UV or without radiation and the swelling ratio were analyzed as three experimental design responses The effects of cross linking agents, gum, nanoparticles, and pH of the medium on responses are interpreted The absorption percentages of methylene blue were 88 2 96 9% and 89 6 99 2% in visible light and ultraviolet radiation, respectively Although the absorption of hydrogels required inflation, there was no evident relation between absorption and swelling Nevertheless, increasing the pH boosted swelling and absorption significantly
