Abstract
Cilj ovog rada bio je istražiti biosorpcijski potencijal inaktivne biomase ljekovite gljive Fomitopsis pinicola za uklanjanje sintetskog bojila malahitnog zelenila (MZ) iz vode. Šaržnim postupkom istraživani su različiti čimbenici koji utječu na proces biosorpcije: koncentracija biosorbensa (0.5 – 10 g/L), vrijeme kontakta (1 - 180 min), početna koncentracija bojila (10 – 200 mg/L) i pH ( 4 - 10). Postotak uklanjanja bojila se povećao s povećanjem koncentracije biosorbensa i vremena kontakta između biosorbensa i MZ. Povećanje početne koncentracije bojila od 10 do 200 mg/L dovelo je do smanjenja postotka uklanjanja bojila ( od 96 do 42.67 %) i povećanja količine bojila adsorbirane po gramu biosorbensa (od 4.33 do 31.97 mg/g. Uklanjanje MZ iz sintetske otpadne vode s dodatkom bojila (koncentracija bojila od 10 do 100 mg/L) je bilo jednako učinkovito kao uklanjanje MZ iz modelnih otopina, pri čemu je postotak uklanjanja bojila također opadao s porastom koncentracije bojila od 96.75 do 62.6 %. Veći postotak uklanjanja bojila, odnosno učinkovitost biosorpcije postignuta je pri pH > 7. Eksperimentalno dobiveni podatci analizirani su pomoću ravnotežnih adsorpcijskih modela (Freundlich i Langmuir). Rezultati su pokazali kako Freundlichov model nešto bolje opisuje proces biosorpcije MZ na inaktivnu biomasu Fomitopsis pinicola. Kintetički model pseudo-drugog reda pokazuje bolje slaganje s eksperimentalnim podatcima od modela pseudo-prvog reda. Rezultati ukazuju da ekstrahirana inaktivna biomasa ljekovite gljive Fomitopsis pinicola ima potencijal za upotrebu u remedijaciji otpadnih voda onečišćenih sintetskim bojilom malahitnim zelenilom.
Abstract (english)
The aim of this study was to investigate the biosorptive potential of the inactive biomass of the medicinal mushroom Fomitopsis pinicola to remove the synthetic dye malachite green (MG) from water. Various factors affecting the biosorption process were investigated in a batch procedure, namely the concentration of biosorbent (0.5 - 10 g/L), contact time (1 - 180 min), initial dye concentration (10 - 200 mg/L), and pH (4 - 10). The percentage of dye removal increased with increasing biosorbent concentration and contact time between biosorbent and MG. A decrease in the percentage of dye removal (from 96 to 42.67%) and an increase in the amount of dye adsorbed on biomass (from 4.33 to 31.97 mg/g) were observed when the concentration of MG was increased from 10 to 200 mg/L. The removal of MG from synthetic wastewater with the addition of MG (concentration 10-200 mg/L) was as efficient as the removal from MG model solutions, and the percentage of dye removal decreased (from 96.75 to 62.6 %) with the increase of initial dye concentration ranging from to. The pH > 7 favoured the efficiency of biosorption. The data from the model MG solution experiments were analysed using adsorption equilibrium models (Freundlich and Langmuir). The results showed that the Freundlich model described the process of MG biosorption on inactive F. pinicola biomass slightly better. Furthermore, of the two kinetic models used (pseudo-first and pseudo-second-order model) the kinetics of the biosorption process was better described by the pseudo-second-order model. The results suggest that the extracted inactive biomass of the medicinal mushroom F. pinicola has potential for remediation of wastewater contaminated with the synthetic dye malachite green.
