“…[7,63,66]. Different treatment methods, including membrane bioreactors, chemical precipitation, advanced oxidation processes, membrane filtration, and adsorption, have been developed considering the varying concentrations of existing EDCs in aquatic environments and the water quality standards for the reuse of treated water for different purposes [9,37,68,72]. The suitability of treatment processes for the reuse of water depends on the intended use of the treated water, other factors such as the cost of the treatment, energy requirements and available physical space [10,82].…”

In this study, the treatment performance of the process in the removal of Endocrine Disrupting Compounds (EDCs) from domestic wastewater by a laboratory-scale electrooxidation process using Ti/IrO₂/RuO₂ electrodes as an anode was evaluated using response surface method (RSM). The effect of pH, current density, and flow rate on the electrochemical treatment of 17α-ethinylestradiol, β-estradiol, triclosan, and estrone, which are often present in wastewater, has been studied. Using Box-Behnken Design (BBD), the parameters influencing the removal efficiencies were optimized for the Electrooxidation process (EOP), and the models created essential second-order quadratic models for the EOP process. The Response Surface Method yielded results that reasonably agreed with the measured values. The maximum removals of triclosan, 17α-ethinylestradiol, and β-estradiol were attained at 92,90%, 97,76%, and 95,36% respectively, under experimental conditions optimized pH= 3,68, current density= 20 A and flow rate= 8,83 mL/min for EOP. Removal efficiencies have achieved their maximum levels at low pH, high current density, and low flow rate. At the same time, the electrooxidation method could not completely remove the estrone.

“…Organic micropollutants (pharmaceuticals, nutraceuticals, cosmeceuticals, pesticides, dyes, microplastics) have been identified as emerging water contaminants that present possible threats to ecological environments [ 1 , 2 , 3 ]. Agriculture is the source of various organic micropollutants, among which pesticide residues require continuous monitoring in water [ 4 , 5 , 6 ].…”

An enzyme-linked fluorescent immunoassay (ELFIA) method has been developed for the quantitative analytical determination of the herbicide active ingredient glyphosate in environmental matrices (surface water, soil, and plant tissues). Glyphosate, as a ubiquitous agricultural pollutant, is a xenobiotic substance with exposure in aquatic and terrestrial ecosystems due its extremely high worldwide application rate. The immunoassay developed in Project Aquafluosense is part of a fluorescence-based instrumentation setup for the in situ determination of several characteristic water quality parameters. The 96-well microplate-based competitive immunoassay method applies fluorescence signal detection in the concentration range of 0–100 ng/mL glyphosate. Application of the fluorescent signal provides a limit of detection of 0.09 ng/mL, which is 2.5-fold lower than that obtained with a visual absorbance signal. Beside the improved limit of detection, determination by fluorescence provided a wider and steeper dynamic range for glyphosate detection. No matrix effect appeared for the undiluted surface water samples, while plant tissues and soil samples required dilution rates of 1:10 and 1:100, respectively. No cross-reaction was determined with the main metabolite of glyphosate, N-aminomethylphosphonic acid, and related compounds.

Nanofiltration (NF) is an effective technology for removing trace organic contaminants (TrOCs), while the inherent trade-off effect between water permeance and solute rejections hinders its widespread application in water treatment. Herein, we propose a novel scheme of "monomers with sacrificial groups" to regulate the microstructure of the polyamide active layer via introducing a hydrolyzable ester group onto piperazine to control the diffusion and interfacial polymerization process. The achieved benefits include narrowing the pore size, improving the interpore connectivity, enhancing the microporosity, and reducing the active layer thickness, which collectively realized the simultaneous improvement of water permeance and enhancement of TrOCs rejection performance. The resulting membranes were superior to both the control and commercial membranes, especially in water-TrOCs selectivity. The effects of using the new monomers on the membrane physicochemical properties were systematically studied, and underlying mechanisms for the enhanced separation performance were further revealed by simulating the polymerization process through density functional theory calculation and measuring the trans-interface diffusion rate of monomers. This study demonstrates a novel promising NF membrane synthesis strategy by designing the structure of reaction monomers for achieving excellent rejection of TrOCs with a low energy input in water treatment.
