The present study investigated the potential of wheat straw for the removal of nitrobenzene (NB) from aqueous solution. The raw wheat straw samples were characterized by scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FT-IR). The effects of contact time, temperature, particle size, initial pH, loading and initial concentration were investigated in batch reactor studies. The applicability of the Langmuir and Freund-lich adsorption isotherms for the present system was tested. The adsorption equilibration time was only about 60 min. Adsorption of NB increased with increasing temperature from 15 to 35 °C, and was independent of pH. The optimal NB adsorption efficiency was achieved when the wheat straw dose was 30 g/L, with optimum particle size of 40-100 mesh. The adsorption was well fitted to Langmuir and Freundlich adsorption isotherms. The results above confirmed that wheat straw is an inexpensive, rapid, effective and environmentally friendly adsorbent for NB removal. [ABSTRACT FROM AUTHOR] |
