Abstract

Poly acrylamido-co-3-methacrylopropyl trimethyl ammonium chloride -Chitosan semi-IPN hydrogels were prepared by free-radical polymerization of the monomer acrylamide AAm and the cationic comonomer 3- methacrylo propyl trimethyl ammonium chloride MAPTAC with N,N-methylene bisacrylamide BAAm as the crosslinker in presence of chitosan, which is also cationic natural polymer. The swelling properties were investigated by using gravimetric method, whereas morphological structure and mechanical performance of the hydrogels were identified by employing scanning electron microscopy SEM and uniaxial compression machine, respectively. Potassium nitrate was used as the model fertilizer and its loading and release experiments were carried out with conductimetric measurements. All the results indicated that both cationic MAPTAC units and chitosan were strongly influenced the gel properties from pore structures and swelling properties to nitrate loading and release % values due to the repulsion forces formed between the positive charges in MAPTAC and chitosan, as well as the interaction between these ionic groups and water molecules. The new semi-IPN hydrogels exhibited good slow nitrate release, better swelling and improved mechanical performances in especially some composition . Thus it can be concluded that the new semi-IPN hydrogels have a potential to use them as a nitrate fertilizer carrier. Especially the further investigations performed with A-1M-0.05C hydrogel in soil media revealed that the hydrogel at this combination can be evaluated as one of the promising materials which can be safely used as controlled fertilizer release system..
