Abstract
U ovom radu ispitana je mogućnost uklanjanja kationskog bojila metilenskog modrila iz vodenih otopina adsorpcijom na različite bioadsorbense.Kao bioadsorbensi korišteni su lignocelulozni otpadni materijali drvne industrije (piljevine topole, hrasta i bukve) i prehrambene industrije (repini rezanci, pivski trop i trop jabuke). Postotak uklanjanja metilenskog modrila iz vodene otopine bojila koncentracije 15 mg L-1 (madsorbensa = 1 g, Vadsorbata= 100 mL, t = 25 ⁰C, vrijeme kontakta 300 min) iznosio je više od 90% za sve korištene bioadsorbense. Za daljnja istraživanja utjecaja početne koncentracije bojila, mase adsorbensa, temperature i pH na učinkovitost uklanjanja bojila adsorpcijom odabrani su piljevina topole i pivski trop. Smanjenjem početne koncentracije bojila i povećanjem mase adsorbensa došlo je do povećanja postotka uklanjanja, što je najbolje vidljivo u prvih 30 min eksperimenta kada je uklanjanje bojila najintenzivnije, dok je nakon 300 min razlika u postotku uklanjanja vrlo mala za sve provedene eksperimente (uključujući i utjecaj pH i temperature). Temperatura nije imala značajnijeg utjecaja na postotak uklanjanja bojila, dok je smanjenje pH dovelo do smanjenja postotka uklanjanja metilenskog modrila kada je kao adsorbens korišten pivski trop. Biološkom obradom obojenog pivskog tropa pomoću gljive bijelog truljenja T. versicolor uzgajane u uvjetima fermentacije na čvrstim nosačima u trajanju od 30 dana došlo je do kontinuiranog porasta ukupne promjene boje i promjene intenziteta boje fermentiranih uzoraka u odnosu na abiotičku kontrolu.
Abstract (english)
In this study the ability of different bioadsorbents to remove cationic dye methylene blue from aqueous solution was investigated. Lignocellulosic waste materials from wood industry (poplar sawdust, oak sawdust and beech sawdust) and food industry (sugar beet waste, spent beer grains and apple pomace) were used as bioadsorbents. The percentage of methylene blue removal from aqueous solution concentration of 15 mg L-1 (m adsorbent=1 g, V dye solution= 100 mL, t =25 °C, contact time 300 min) was more than 90% for all tested bioadsorbents. Poplar sawdust and spent beer grains were selected as bioadsorbents for further adsorption experiments investigating the effect of initial dye concentration, adsorbent dosage, temperature and solution pH on dye removal. The percentage of dye removal increased with the decrease of the initial dye concentration and increase of the adsorbent mass, which was the most obvious within the first 30 min of the experiment. After 300 min contact time the percentage removal difference was insignificant for all the experiments (including the effect of temperature and pH on dye adsorption). The temperature had no significant effect on the percentage removal, while the decrease in pH caused reduction of percentage removal of methylene blue when spent beer grains were used as bioadsorbent. Solid-state fermentation of dye-adsorbed spent beer grains was carried out for 30 days using white-rot fungus T. versicolor. The continuous increase of total colour change and colour intensity change of fermented samples compared to their abiotic controls was observed.
