“…The persistent increase in anthropogenic activities has led to the indiscriminate release of chemicals that contaminate waterbodies and negatively affect the aquatic ecosystem owing to high toxicity and persistence in the environment. 1,2 These chemicals are of natural and synthetic origin and include endocrine disrupting chemicals with concentrations ranging from ng L −1 to g L −1 in aquatic bodies. 3,4…”

“…Industrial waste from incineration, mining, battery production, and pigments contains mercury and heavy metals. All of these heavy metals play an essential role in contaminating drinking water. − The worldwide impact of heavy metals on water has reached an alarming level due to industrial growth in developing and developed countries . Among all heavy metals, mercury is the most dangerous due to its high exposure and toxicity to human health.…”

This computational study analyzes mercury adsorption from wastewater using inversed-vulcanized porous sulfur copolymers. Two inverse-vulcanized sulfur copolymer foams reported previously were selected for this study. These foams were prepared using poly (sodium 4-styrene sulfonate) and sodium chloride as porogens. Mercury adsorption on these copolymer foams was studied and compared to elemental sulfur. Various process parameters were examined, such as mercury-ion concentrations, the volumetric flow rate of wastewater, temperature, and thickness of the adsorbent material. Studying all of these parameters helps optimize the process conditions at high adsorption capacity and predict suitable operational parameters for industrial applications. The CFD model results are validated with the experimental results at fixed and varied operational conditions. The inverse-vulcanized sulfur copolymer foams prepared by using the poly (sodium 4-styrene sulfonate) commoner present high porosity (59.09%), less density (0.53 g/cm 3 ), and smaller particle size (20−50 μm). Therefore, it exhibits high adsorption efficiency in the case of experimental (244 μg/g) and CFD simulations (249 μg/g) compared to other samples.

“…Emerging contaminants (ECs) refer to a wide range of chemical and biological pollutants that have been recently detected in the environment and have the potential to cause adverse effects on human health and the environment [1][2][3]. These contaminants can arise from many sources such as industrial and agricultural activities, pharmaceuticals, personal care products, and household chemicals [4]. Their impacts on the environment can include effects on aquatic and terrestrial ecosystems, such as changes in species composition, reproductive and developmental abnormalities, and biodiversity declines.…”

“…However, studies have found that these estrogens can be present in the environment at low levels, measured in nanograms per liter (ng/L). For example, in the United States, it was shown that the concentrations of E1 and E2 in river water samples ranged from less than 1 to 65 ng•L −1 , with an average concentration of 8 ng•L −1 [4]. EE2 was detected at concentrations ranging from less than 1 to 58 ng L −1 , with an average concentration of 3 ng L −1 .…”

“…The occurrence of organic pollutants in aquatic environments is mainly attributed to the discharge of wastewater effluents. Indeed, existing wastewater treatment plants (WWTPs) are not designed to efficiently and completely eliminate these organic pollutants [4,16]. Thus, several technologies have been developed to remove micropollutants from water and wastewater, e.g., adsorption by activated carbon [17][18][19], ozonation [20,21], and advanced oxidation processes (AOPs) have been developed to remove micropollutants from water and wastewater.…”

Many approaches have been investigated to eliminate pharmaceuticals in wastewater treatment plants during the last decades. However, a lack of sustainable and efficient solutions exists for the removal of hormones by advanced oxidation processes. The aim of this study was to synthesize and test new photoactive bio composites for the elimination of these molecules in wastewater effluents. The new materials were obtained from the activated carbon (AC) of Arganian spinosa tree nutshells and titanium tetrachloride by the sol gel method. SEM analysis allowed one to confirm the formation of TiO2 particles homogeneously dispersed at the surface of AC with a controlled titanium dioxide mass ratio, a specific TiO2 anatase structure, and a highly specific surface area, evidenced by ATG, XRD, and BET analysis, respectively. The obtained composites were revealed to quantitatively absorb carbamazepine (CBZ), which is used as a referred pharmaceutical, and leading to its total elimination after 40 min under irradiation with the most effective material. TiO2 high content disfavors CBZ adsorption but improves its degradation. In the presence of the composite, three hormones (17α-ethinylestradiol, estrone, and β-estradiol) are partially adsorbed onto the composite and totally degraded after 60 min under UV light exposure. This study constitutes a promising solution for the efficient treatment of wastewater contaminated by hormones.
