The Use of Acrylamide-Crotonic Acid Nested Network Structured Hydrogels for Adsorption of the Methylene Blue
Abstract
In this study acrylamide-crotonic acid hydrogels are used as adsorbent
for removal of methylene blue. The effects of pH, crotonic acid percentage,
initial dye concentration and reusage number on the adsorption of the dye are
investigated. When the pH increased adsorption also slightly increased with the
hydrogels made up of only acrylamide. With the acrylamide crotonic acid
hydrogels adsorption rates are similar in pH 7,9 and 10 but there is a significant
decrease in pH 8. Adsorption increases with the increasing crotonic acid
percentage in hydrogels. In addition, the adsorption-desorption results showed
that the adsorption capacity of the hydrogel was not changed even after 20
times repeated use. Results show that acrylamide-crotonic acid hydrogels can be
used as adsorbent for dye removal in industrial textile waste water.
