Bio-oils usually contain many types of compounds with various chemical properties. A bio-oil sample derived from rice husk through rapid pyrolysis was fractioned using solvent- or solid-extraction techniques based on their various properties. Ultraviolet–visible spectroscopy, three-dimensional excitation–emission matrix (EEM) fluorescence spectroscopy and Fourier transform infrared spectroscopy were...
The reductive degradation of nitrobenzene (NB) by zero-valent iron was investigated. Experimental results showed that the degradation of NB was influenced by pH and NB concentration. The optimum pH value was found to be 3.0 for the reductive degradation of NB in the tested pH ranges of 3.0-12.0. The formation rate of aniline, a major reductive product of NB, followed zero-order kinetics at various...
