Sažetak
The aim of this study was to investigate the biosrptive potential of the inactive biomass of the medicinal mushroom Fomitopsis pinicola (fruiting body and mycellial biomass) 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 - 100 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 58%) and an increase in the amount of dye adsorbed on biomass (from 4.33 to 19.61 mg/g) were observed when the concentration of MG was increased from 10 to 100 mg/L. The removal of MG from synthetic wastewater with the addition of MG was as efficient as the removal from MG model solutions, with the percentage of dye removal ranging from 62.6 to 96.75%. 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. 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. synthetic dyes.
