A Novel Sustainable Biosorbent (ulocladium Consortiale) Proposal With Central Composite Design To Reduce Water Pollution
(Springer International Publishing Ag, 2021) Malkoc, Semra; Anagun, Ahmet Sermet; Deniz, Nurcan
Biosorption is an efficient and environmental-friendly technology for the decontamination of dyes from industrial wastewater. These properties bio absorbent usage instead of commercial chemicals supports not only the economic dimension, but also environment and social dimensions of sustainability. As a novel bioadsorbent, methylene blue-resistant fungal strain Ulocladium consortiale was isolated from the Lake Tuz (Turkey). The effect of four independent variables pH (7-11), initial dye concentration (10-50 mg/L), biomass dosage (0.1-0.5 g/mL), and contact time (2.5-12.5 min) was studied on methylene biosorption by employing U. consortiale using batch mode. Optimum conditions were selected for maximum biosorption. Central Composite Design (CCD) of Response Surface Methodology (RSM) an ideal solution for fitting a second-order response surface model was performed to determine the optimum levels of parameters and to spot the correlation between the various parameters. The highest removal efficiency (R, %) of methylene blue was achieved with 92.69 % and U. consortiale showed the highest biosorption capacity (q, mg/g) 181.28 mg/g. This efficiency was obtained at 10 pH, 46 mg/L initial dye concentration, 0.2 g/mL biomass dosage, and 2.5 min contact time. The results of CCD of RSM show that Ulocladium consortiale is a suitable and sustainable novel biosorbent can be used in for methylene blue removal under optimal conditions.
