| description abstract | This study examined the effects of pH, dosage, and stirring time on the removal of oil and Cr(VI) from simulated wastewater by pectin obtained from citrus byproducts. After pectin modification by etherification and polyaluminum chloride (PAC) impregnation, the extract removed highly concentrated oil and Cr(VI) from wastewater. Fourier transform infrared spectroscopy, scanning electron microscopy, and X-ray diffraction were used to characterize the flocculants and confirm modification of the pectin. An orthogonal factorial experiment with factors of stirring time, dosage, and pH was used to optimize the conditions for contaminant removal by the modified pectin. The average removal rates were 79 and 77% for oil and Cr(VI), respectively. A central composite design with factors of PAC, zinc sulfate ( | |
