Activated carbons impregnated with iron oxide nanoparticles for enhanced removal of bisphenol A and natural organic matter.

The removal of bisphenol A (BPA) is important for the provision of safe drinking water, but its removal in the presence of natural organic matter (NOM) is challenging. Thus, the present study involved the fabrication and characterization of powdered activated carbons impregnated with iron oxide nanoparticles (IONPACs) with respect to the simultaneous removal of BPA and NOM. The number of Fe ions loaded into the PAC pores was optimized in terms of exposure time.

The methods of identification, analysis, and removal of endocrine disrupting compounds (EDCs) in water.

The information regarding endocrine disrupting compounds (EDCs) was reviewed, including the definition and characteristics, the recent research trends concerning identification and analytical methods, and the applicable removal processes. EDCs include various types of natural and synthetic chemical compounds presenting the mimicking or inhibition of the reproductive action of the endocrine system in animals and humans. The ubiquitous presence with trace level concentrations and the wide diversity are the reported characteristics of EDCs.
