Removal of phthalate from papermaking wastewater by MIL-101(Fe) in the presence of persulfate
Source abstract
Abstract
Phthalates are found in most papermaking wastewater, as are various other pollutants. Phthalates such as diethyl phthalate (DEP) and dibutyl phthalate (DBP) are endocrine-disrupting compounds (EDCs). The objective of this research was to use metal organic frameworks (MOFs) MIL-101(Fe) as a new-style adsorbing material and persulfate (PS) activator for removing DEP and DBP from artificial aqueous model solutions. We used X-ray diffractometer, scanning electron microscope, and Fourier transform infrared spectroscopy technologies to characterize the MIL-101(Fe). More than 80% of the DEP and DBP were removed with a MIL-101(Fe)/PS system over a 5 h period when the initial concentrations of the pollutants (DEP or DBP) were around 3 ppm. MIL-101(Fe) was able to absorb the pollutants and activate persulfate, which together contributed to phthalate removal. As the amount of MIL-101 and PS was increased, the percentage of removed phthalate increased gradually. We concluded that the MIL-101(Fe)/PSsystem removed phthalate effectively from papermaking wastewater.
