Evaluation of adsorption performance and mechanisms of a highly effective 3D boron-doped graphene composite for amitriptyline pharmaceutical removal

Journal of Environmental Management, Journal Year: 2023, Volume and Issue: 344, P. 118363 - 118363

Published: July 4, 2023

Three-dimensional heteroatom-doped graphene presents a state-of-the-art approach for effective remediation of pharmaceutical wastewater on account its distinguished adsorption and physicochemical attributes. Amitriptyline is an emerging tricyclic antidepressant pollutant posing severe risks to living habitats through water supply food chain. With ultra-large surface area plentiful chemical functional groups, oxide favorable adsorbent decontaminating polluted water. Herein, new boron-doped composite reinforced with carboxymethyl cellulose was successfully developed via solution-based synthesis. Characterization study revealed that the formed by sheets intertwined into porous network engrafted 13.37 at% boron. The has zero charge at pH 6 contained various groups favoring attachment amitriptyline. It also found mere 10 mg able achieve relatively high amitriptyline removal (89.31%) 50 ppm solution concentration 30 °C. attained equilibrium within 60 min across concentrations ranging from 300 ppm. kinetic were well correlated pseudo-second-order Langmuir models, respectively, portraying highest capacity 737.4 mg/g. Notably, predominant mechanism chemisorption assisted physisorption contributed outstanding saturated sufficiently regenerated using ethanol eluent. results highlighted impressive performance as-synthesized in treating amitriptyline-containing waste effluent.

Abstract There is growing evidence of negative impacts antidepressants on behavior aquatic non-target organisms. Accurate environmental risk assessment requires an understanding whether with similar modes action have consistent impacts. Here, we tested the effect acute exposure to two antidepressants, fluoxetine and venlafaxine (0–50 µg/L), organism, i.e., freshwater pond snail, Lymnaea stagnalis . As compounds interact chemical cues in ecosystems, also effects altered presence bile extract containing 5α-cyprinol sulfate (5α-CPS), a characterized kairomone natural predator, common carp ( Cyprinus carpio ). Behavior was studied using automated tracking analysis various locomotion parameters L. stagnalis. Our results suggest that there are differences upon fluoxetine. We found strong for non-monotonic dose response exposure, whereas only showed weak specific concentration. Combined 5α-CPS reduced intensity observed absence 5α-CPS, possibly due bioavailability compounds. The highlight need acknowledging different mechanisms among while investigating their risks. In addition, our underline importance reporting non-significant individual variation assessment. Graphical
