Heterogeneous photocatalysis is a technology widely applied to water purification and wastewater treatment under ultraviolet (UV) or even sunlight irradiation for the removal of variety environmental pollutants into harmless species. Application membrane immobilization semiconductors their suitability in photocatalytic degradation dyes have recently been developed. Integration with processes sig...

Statistical regression models are presented, that explain the observed variations, across urban areas, in the concentrations of two major pollutants, ozone and carbon monoxide. Model specification and estimation are based on an explicit and new spatial framework derived from the theoretical concept of well-mixed cells, whereby the basic Fickian system of diffusion equations is integrated over t...

Advanced oxidation processes are attractive methods for treating wastewater containing refractory organic substances. Hybrid reactors utilizing mist generated by ultrasound and photocatalysts have been proposed to enhance pollutant removal. However, the functions of ultraviolet, ultrasound, mist, photocatalyst in hybrid reactor not clarified. The aim this study is investigate these comparing re...

Nature-based solutions have been identified by the European Union as being critical for the enhancement of environmental qualities in cities, where urban and peri-urban forests play a key role in air quality amelioration through pollutant removal. A remote sensing and geographic information system (GIS) approach was applied to the Metropolitan City (MC) of Rome to assess the seasonal particulat...

Pyrene removal by polycation-montmorillonite (MMT) composites and granulated activated carbon (GAC) in the presence of humic acid (HA) was examined. Pyrene, HA, and sorbent interactions were characterized by FTIR, fluorescence and zeta measurements, adsorption, and column filtration experiments. Pyrene binding coefficients to the macromolecules were in the order of PVPcoS (poly-4-vinylpiridine-...

Stormwater management for water quality control is a relatively recent technology. Initially urban stormwater was considered a water quantity problem solved by rapidly draining runoff into sewers, ditches or directly into lakes and rivers. By the mid-1970s studies showed over half the pollutant loads entering Florida waters came from non-point sources (stormwater) caused in part by paving, ditc...

Antibiotics have been identified as emerging pollutants, and they increasingly threaten the safety of mariculture; thus, effective treatment methods are urgently needed. In this study, Fe(II)-peroxymonosulfate-modified clay (Fe-PMS-MC), an mineral complex for harmful algal bloom control, was tested sulfamethoxazole (SMX) removal from seawater. The results showed that SMX efficiency increased gr...

Heterogeneous photocatalysis has emerged as a promising alternative for both micropollutant removal and bacterial inactivation under solar irradiation. Among variety of photocatalysts explored in the literature, graphite carbon nitride (g-C3N4) is metal-free semiconductor with acceptable chemical stability, low toxicity, excellent cost-effectiveness. To minimize its high charge recombination ra...
