Effective removal of non-steroidal anti-inflammatory drug from wastewater by adsorption process using acid-treated Fagopyrum esculentum husk
(Springer Science + Business Media, 2022)
In this work, buckwheat husks (Fagopyrum esculentum) were modified by acid treatment and posteriorly employed to remove the ketoprofen in batch adsorption. The characterization results indicated that a more irregular surface ...
Simultaneous production of mesoporous biochar and palmitic acid by pyrolysis of brewing industry wastes
(Universidad de la Costa, 2020)
Pyrolysis of malt bagasse was carried out to obtain simultaneously a mesoporous biochar and an oil fraction rich in palmitic acid. The best result for biochar production was at 500 °C with holding time of 10 min. The yields ...
Possibilities of using silicate rock powder: an overview
(Corporación Universidad de la Costa, 2021-03-11)
This study evaluates the on use of crushed rocks (remineralizers) to increase soil fertility levels and which contributed to increase agricultural productivity, recovery of degraded areas, decontamination of water, and ...
Adsorptive decontamination of wastewater containing methylene blue dye using golden trumpet tree bark (Handroanthus albus)
(Universidad de la Costa, 2019-09-05)
The golden trumpet tree bark (GTB), a wood-processing residue, was tested as adsorbent material for decontamination of wastewaters containing methylene blue dye (MB). The powdered material was preponderantly amorphous, ...
Source identification and global implications of black carbon
(Corporación Universidad de la Costa, 2021-01-23)
Black carbon (BC) is one of the short-lived air pollutants that contributes significantly to aerosol radiative forcing and global climate change. It is emitted by the incomplete combustion of fossil fuels, biofuels, and ...
Release kinetics of multi-nutrients from volcanic rock mining by-products: Evidences for their use as a soil remineralizer
(Corporación Universidad de la Costa, 2021)
Great quantities of stone by-products are stored alongside different exploiting mines in south Brazil, which are becoming an unsustainable environmental issue. Powder materials of andesite and dacite rocks were obtained ...
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, ...
Solid wastes from the enzyme production as a potential biosorbent to treat colored effluents containing crystal violet dye
(Universidad de la Costa, 2020-01-15)
Sugarcane bagasse, a largely available waste worldwide, was submitted to solid-state fermentation (SSF) using the fungus Metarhizium anisopliae, aiming to produce enzymes. The solid waste generated from SSF was tested as ...
Evaluation of Ocotea puberula bark powder (OPBP) as an effective adsorbent to uptake crystal violet from colored effluents: alternative kinetic approaches
(Universidad de la Costa, 2020-04-30)
The Ocotea puberula bark powder (OPBP) was evaluated as an effective adsorbent for the removal of crystal violet (CV) from colored effluents. OPBP was characterized and presented a surface with large cavities, organized ...
Influence of curing time on the fire performance of solid reinforced concrete plates
(Corporación Universidad de la Costa, 2020-01-07)
When reinforced concrete elements are subjected to high temperatures, such as in a fire, they are susceptible to physical and chemical changes that cause spalling, thereby undermining their performance under such conditions. ...
