Hormones are bioactive, ubiquitous, and persistent organic molecules that demand effective treatment when released in the environment. However, most conventional treatments are inefficient or not suitable for large-scale applications. This study describes the use of supercritical water (SCW) technology in the degradation of hormones in wastewater from the pharmaceutical industry. Initially, the treatment was developed with synthetic wastewater (SW) containing hormone prepared from commercial desogestrel ...

Abstract The characteristics and diclofenac adsorption properties of a carbon adsorbent prepared from palm kernel shells were studied. The adsorbent prepared via hydrothermal carbonization followed by an activation in nitrogen flow had a mesoporous structure with homogenous pore distribution and the specific surface area of 131 m 2 g −1 . The Raman spectra showed a formation of graphene or graphite structures in the material during activation with small number of defects based on its I D /I G ratio ...

The worrying hydric crisis and the increasing water contamination by emerging pollutants around the world stimulate the development of activated carbons (AC) for the removal of endocrine disruptors, including bisphenol-A (BPA). For this reason, a new approach for the synthesis of AC from hydrochar produced through hydrothermal carbonization (HTC) of Brazilian Cerrado biomass (Magonia pubescens–Sapindaceae) and physical activation using water vapor is highlighted. Compared to the traditional method of ...

Bisphenol-A is widely used chemical in industry and unfortunately often detected in natural waters. Considered as an emerging pollutant, bisphenol-A represents an environmental problem due to its endocrine-disrupting behavior. The production of activated carbon from alternative precursors has shown to be attractive in the removal of emerging pollutants from the water. Activated carbon was produced from waste coffee by physical and chemical activation and applied in the removal of bisphenol-A. The ...
