High-performance removal of 2,4-dichlorophenoxyacetic acid herbicide in water using activated carbon derived from Queen palm fruit endocarp (Syagrus romanzoffiana)
(Corporación Universidad de la Costa, 2021-02)
In this work, an activated carbon sample with a high adsorptive performance for the herbicide 2,4-dichlorophenoxyacetic acid (2,4-D) was prepared from queen palm endocarp (Syagrus romanzoffiana) by pyrolysis process. The ...
Adsorbents for glyphosate removal in contaminated waters: a review
(2020-10-26)
Glyphosate is an herbicide used to control weeds and optimize agricultural production. However, since glyphosate is an emerging pollutant claimed to be potentially carcinogenic, glyphosate pollution of soils and water is ...
Formation of carbon quantum dots and graphene nanosheets from different abundant carbonaceous materials
(Universidad de la Costa, 2020-03-20)
Carbon quantum dots (CQDs) and graphene nanosheets (GNs) are one of the most attractive fluorescent carbon nano-sized materials with unique features of optical and physico-chemical properties having various applications ...
Air quality and PM10-associated poly-aromatic hydrocarbons around the railway traffic area: statistical and air mass trajectory approaches
(Universidad de la Costa, 2019)
Diesel engine railway traffic causes atmosphere pollution due to the exhaust emission which may be harmful to the passengers as well as workers. In this study, the air quality and PM 10 concentrations were evaluated around ...
Composite carbon materials from winery composted waste for the treatment of effluents contaminated with ketoprofen and 2-nitrophenol
(Corporación Universidad de la Costa, 2021)
The present work consisted of preparing and characterizing composite carbon materials (WRCC) from raw winery residues (WR) activated with zinc chloride to produce a carbon adsorbent. The WRCC was used for the adsorption ...
Geochemical fractionation of hazardous elements in fresh and drilled weathered South African coal fly ashes
(Universidad de la Costa, 2020-01-03)
The chemical reactions of dry-disposed ash dump, ingressed oxygen, carbon dioxide, and infiltrating rainwater affect mineralogical transformation, redistribution, and migration of chemical species. Composite samples of ...
Composition and porosity study of original and restoration materials included in a coastal historical construction
(Universidad de la Costa, 2018-05-22)
The materials used for the building constructions can suffer during their life numerous deterioration processes induced by different anthropogenic and natural factors. For this reason, optimal restoration works are vitally ...
COVID-19 mortality and exposure to airborne PM2.5: a lag time correlation
(Corporación Universidad de la Costa, 2020-02-01)
COVID-19 has escalated into one of the most serious crises in the 21st Century. Given the rapid spread of SARS-CoV-2 and its high mortality rate, here we investigate the impact and relationship of airborne PM2.5 to COVID-19 ...
Comparative carbon emission assessments of recycled and natural aggregate concrete: Environmental influence of cement content
(Corporación Universidad de la Costa, 2021)
This work examines the environmental and geochemical impact of recycled aggregate concrete production with properties representative for structural applications. The environmental influence of cement content, aggregate ...
Exposure to nanometric pollutants in primary schools: Environmental implications
(Urban Climate, 2019-12-21)
School children are highly susceptible to chemicals in the atmosphere. Some studies have demonstrated that the pollution is related to respiratory problems and impaired cognitive development in children. In this context, ...
