| description |
Bamboo supported manganese (BS-Mn) nanocomposite was prepared in a single pot system via bottom-up approach using a chemical reduction method. Langmuir surface area, BET surface area, and Single pore surface area were 349.70 m2/g, 218.90 m2/g, and 213.50 m2/g, respectively. The pore size (24.34 Ȧ); pore volume (0.489 cm3); point of zero charge (5.8); bulk density (0.0035 gcm-3); specific surface area (33.00 m2/g) by Saer’s method and functional group of BS Mn nanocomposite determined using Fourier Transform Infrared Spectrophotometer (FTIR). Various operational parameters affecting adsorption of Cu(II) such as adsorbent dose (100 mg), pH (6), contact time (90 min), initial Cu(II) ions concentration (100 mg/L) and temperature (298 K) were determined in a batch technique. Kinetic data were best fitted to pseudo second-order model validated by sum of square error (SSE) and Chi-square test (χ2). Equilibrium data were better described by Langmuir isotherm model with the monolayer adsorption capacity surpassing those previously reported for Cu(II) uptake. The thermodynamic parameters, ΔGo (- 31.773 kJ mol-1), ΔSo (107.30 J) and ΔHo (+202 kJmol-1) revealed that the adsorption process was feasible, spontaneous and endothermic in nature. The study showed that BS–Mn is a promising nanocomposite which could be utilized for industrial wastewater remediation.
