| Popis: | In the current study, the methylene blue (MB) dye sorption performance of a new biomagnetic composite (MTNC) synthesized by modification with Fe3O4 nanoparticles of industrial tomato processing (Lycopersicon esculentum Mill.) processing solid waste (TW) was investigated. The XRD, BET, SEM, FT-IR and VSM analysis techniques were used in the characterization of MTNC. The specific surface area, total pore volume, micropore volume, mesopore volume, and mean pore diameter values of MTNC are 28.21 m2/g, 0.082 cm3/g, 0.003 cm3/g, 0.079 and 11.06 nm, respectively. Also, its saturation magnetization value was determined to be 24.80 emu/g. The maximum MB sorption capacity of the MTNC determined to be 90.09 mg/g under optimized conditions of the solution pH of 7.0, WPC dosage of 50 mg, contact time of 180 min, and solution temperature of 50 °C. The kinetics and isotherm data were well fitted to the pseudo-second order kinetic and Langmuir isotherm models, respectively. The thermodynamic parameters calculated for the MTNC-MB sorption system proved that the process was spontaneous and endothermic in nature. |
