Abstract
Biorazgradljivi polimerni materijali intenzivno se istražuju zadnjih desetljeća. Njihova primjena postaje sve šira pa tako ponekad zamjenjuju konvencionalne polimere. Jedan od takvih biorazgradljivih polimera je i poli(akril-amid) (PAM) koji ima sve širu primjenu zahvaljujući sposobnosti upijanja i zadržavanja velike količine tekućine. U ovom radu praćena je kinetika bubrenja poli(akril-amida) u nekoliko različitih otopina: destiliranoj vodi, vodovodnoj vodi, otopini Substrala-tekućeg mineralnog gnojiva te u ekstraktu vrtne zemlje. Za ispitivanje su upotrijebljene granule poli(akril-amida). Granule su prije bubrenja odvagane na analitičkoj vagi te su za bubrenje korištene granule otprilike jednake veličine. Stupanj bubrenja određen je gravimetrijskom metodom. Na temelju dobivenih rezultata napravljene su krivulje ovisnosti stupnja bubrenja () o vremenu (t). Utvrđeno je da PAM sporije bubri u ekstraktu vrtne zemlje i Substralu, u odnosu na vodovodnu i destiliranu vodu.
Abstract (english)
Biodegradable polymers have been intensively investigated last decades. Their application becomes wider and they can replace some conventional plastics. One such biodegradable polymer is poly(acryl- amide) (PAM) which has a relatively wide use due to the ability to absorb and retain a large amount of fluid. In this paper poly(acrylamide) swelling kinetics are monitored in several different solutions: distilled water, tap water, Substral solution and garden soil extract. Poly(acrylamide) granules were used for the test. Prior to swelling the granules of roughly the same are weighed on an analytical balance. The swelling degree is determined by a gravimetric method. Based on the obtained results, the dependence of swelling (α) on time (t) was made. It was found that PAM was slightly swollen in garden soil extract and Substral solution, compared to tap water and distilled water.
