“…Shortly after application, a certain portion of the active pesticide components is susceptible to (sub)surface runoff and/or leaching to water and other environmental niches [1], making them ubiquitous and emergent chemicals [2] whose long-term exposure effects to non-target organisms are often insufficiently elucidated. Among them, terbuthylazine, TBA (6-chloro-N 2 -ethyl-N 4 -tert-butyl-1,3,5triazine-2,4-diamine; Fig.…”

“…Consequently, TBA and its metabolites are among most frequently detected pesticides in terrestrial surface and groundwater, as well marine aquatic matrices [7], representing serious threat to environmental and humans health, given its well-known endocrine-disruption capacity [4]. Methods for removal and dissipation of pesticides and other in/organics from aqueous matrices are mostly associated with chemical coagulation [8], sedimentation, filtration [9], adsorption [10][11][12], ion-exchange [13], redox processes and various electro-chemical and biodegradation mechanisms [14], as well as photocatalytical mineralization [2,4]. Adsorptive capacities of synthetic and natural materials (e.g.…”

Due to intensive activities in agriculture, forestry and transport sectors, certain active components of pesticides that are prone to leaching become emergent chemicals in aquatic systems. Terbuthylazine (TBA), as one of widely used broad-spectrum herbicides, has been recognized as relatively (e.g. vs atrazine) more hydrophobic and resistant to biodegradation, dissipates much more slowly in aquatic ecosystems and often exceeds the EU limit for drinking water (0.1 μg/L). The in-depth characterisation of fly ash (FA, from a cogeneration plant facility fuelled by deciduous hardwood chips) using advanced in situ approaches (scanning electron microscopy, X-ray diffraction) raised the hypotheses that developed nano-to-micro-structure and alkaline Ca/Mg/Si-enriched mineralogy of FA could be effectively exploited for removal of TBA from watercourses. Thus, the aim of study was to investigate dissipation dynamic and adsorption mechanism of TBA in aquatic media amended with FA. The results show that 48 h after addition of FA (1% w/v) to watercourse, TBA was completely removed from its initial level (250-fold higher than the EU limit for drinking water), while in the Control (without FA) treatment, TBA remained nearly 80% of its initial amount. The X-ray photoelectron spectral footprint of FA after 48-h exposure to TBA revealed a shift in peak position and intensity among O, Ca, K, Mg and Si, suggesting that their active sites likely participated in adsorption of TBA and its removal from the watercourse. Adsorption kinetics were clearly described by the pseudo-second order model (R 2 = 0.9997), assuming single-layer chemisorption as a rate-controlling mechanism, but multilayer physisorption and intra-pore diffusion could also be present. The equilibrium adsorption data fitted the best to the Langmuir isotherm model, confirming the spontaneous monolayer TBA-FA interaction with a mean maximum adsorption capacity of 84 mg/g FA (1% w/v) after 24-h contact time at 25 °C and pH 12. These results will contribute to formulation and development of novel FA-based polymers, targeted for purification of aquatic ecosystems loaded with TBA and similar compounds that represent threat to environmental and human health.

This review was carried out on removal of flue gases (CO2, SO2, and H2S) that are emitted from various sources. Burning solid fuels for heat, such as natural gas, gasoline, and coal or biomass, results in the production of flue gas. Adsorption of flue gases by utilizing Zeolites was properly explained, including the zeolite synthesis technique, characteristics, zeolite sensitivity, variables that influence the adsorption process, zeolite efficiency, and cost-effectiveness. Zeolites have a notable adsorption capability for CO2, SO2, and H2S, despite their major disadvantage of being poor long-term durability and stability. Remarkable advancements are being made in present-day CO2 capture methods, especially concerning the use of zeolites. Zeolites are unique materials with great potential for CO2 collection because of their tiny holes, high porosity, structural variety, and recyclability. Since atmospheric CO2 concentrations are already more than 415 parts per million, it is imperative to limit future releases of this gas and keep it out of the carbon cycle. The elimination of SO2 by the majority of zeolites was shown to rise with temperatures up to 200 °C and subsequently decrease at higher temperatures. It was also shown that SO2 uptake and breakthrough time are significantly affected by drying zeolite using microwave and traditional heating methods. The sorption capacity and sorbent regenerability of SO2 are sensitive to the presence of other gases in the flue gas, such as O2, CO2, NOx, and water vapor, as well as the reaction temperature. Zeolites must possess strong sulfur loading capacity, good regenerability, and a stable structure to be an effective adsorbent for the removal of H2S. Regarding the utilization of zeolites as adsorbents for the flue gases, new developments, and continuing difficulties have been concluded in this review work.
