摘要: In this study, pure TiO2-nanoparticles and TiO2/sewage sludge (TS) as biomass material were synthesised via a sol–gel method. The adsorption potential of nanosized TiO2 TS for removal Cd(II) was investigated in batch system. prepared adsorbents characterised using X-ray diffraction (XRD), fourier transform infrared spectroscopy (FTIR) transmission electron microscopy (TEM). XRD analysis showed that is amorphous phase before calcination anatase at annealing temperature 400 °C. calcined °C (TS400) found to be the best adsorbent cadmium from aqueous solution. Kinetic isotherm studies carried out by considering parameters, pH, initial concentration contact time. optimum pH value onto TS400 6. Langmuir better fit than Freundlich maximum capacity 29.28 mg/g which higher many oth...
