Environmental aspects of the depreciation of the culturally significant Wall of Cartagena de Indias – Colombia
(Corporación Universidad de la Costa, 2021-02)
Among the diverse archeological relics of the past, the Cartagena de Indias Wall is one of the greatest representations of European cultural architecture in South America. To assess the implication of contamination on the ...
An eco-friendly and low-cost strategy for groundwater defluorination: adsorption of fluoride onto calcinated sludge
(Corporación Universidad de la Costa, 2020-09-28)
The excess of fluoride ions (F−) in water for human supply is a serious public health. The recommended concentration of F− ions by the World Health Organization (WHO) is 1.5 mg L-1. Several groundwater sources around the ...
Effects of atmospheric pollutants on human health and deterioration of medieval historical architecture (North Africa, Tunisia)
(Elsevier BV, 2022-01)
Air pollution is a factor of concern on a global scale, accelerating the deterioration of historic medieval architecture and having harmful effects on human health. The general objective of this study is to understand the ...
Geochemical study of submicron particulate matter (PM1) in a metropolitan area
(Corporación Universidad de la Costa, 2020-12-30)
Air pollution has become a major problem in urban areas due to increasing industrialization and urbanization. In this study ambient concentrations of PM1 and metal concentrations as well as source contributions were ...
Preparation of alumina-supported Fe-Al-La composite for fluoride removal from an aqueous matrix
(Springer Science + Business Media, 2023)
Using groundwater for human consumption is an alternative for places with
no nearby surface water resources. Fluoride is commonly found in
groundwater, and the consumption of this water for a prolonged time in
concentrations ...
Synthesis of citrate–modified cufes2 catalyst with significant effect on the photo–fenton degradation efficiency of bisphenol a under visible light and near–neutral PH
(Universidad de la Costa, 2020-03-09)
In this study, for the first time, citric acid was employed as a chelating agent in CuFeS2 synthesis in order to accelerate the regeneration of Fe2+ during the photo–Fenton reaction, promoting a faster production of •OH ...
Improved catalytic activity of EDTA–modified BiFeO3 powders for remarkable degradation of procion red by heterogeneous photo–Fenton process
(Universidad de la Costa, 2020-03-13)
For the first time, heterogeneous photo–Fenton degradation of Procion Red dye under visible irradiation was investigated using ferrite bismuth (BiFeO3) catalysts synthesized by hydrothermal method with and without EDTA. ...
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 ...
Portable dehumidifiers as an original matrix for the study of inhalable nanoparticles in school
(Universidad de la Costa, 2020-06-06)
Good air quality is documented as a significant factor of social justice. The human health hazards associated with air pollution are not distributed equally across cities; the most vulnerable people are more exposed to ...
Development of a biosponge based on Luffa cylindrica and crosslinked chitosan for Allura red AC adsorption
(Corporación Universidad de la Costa, 2021)
A new bioadsorbent from Luffa cylindrica and cross-linked chitosan was proposed in the present study. Luffa was used as a natural support medium for chitosan crosslinked with glutaraldehyde (LCsG) and epichlorohydrin (LCsE). ...
