Preparation and characterization of biodegradable gelatin-PAAm-based IPN hydrogels for controlled release of maleic acid to improve the solubility of phosphate fertilizers
Source abstract
Abstract
In this study, interpenetrating polymer network (IPN) hydrogel systems including maleic acid (MA) were constituted to improve the solubility of phosphate fertilizers. A series of full and semi-IPN hydrogels were prepared from various gelatin/polyacrylamide mixtures by using two different cross-linkers. The effects of polymer composition on the morphological structures and swelling behaviors of the hydrogels were investigated. The swelling values of all hydrogels were found to be in between 435% and 830%. MA release from load0ed hydrogels was followed and it was determined that MA-loaded hydrogels efficiently decreased pH and improved the solubility of Ca3(PO4)2 in releasing medium.
