Trapping of Ag+, Cu2+, and Co2+ by faujasite zeolite Y: new interpretations of the adsorption mechanism via DFT and statistical modeling investigation
(Corporación Universidad de la Costa, 2020-11-13)
This work evaluated the potential of a synthesized faujasite-type zeolite Y as an adsorbent for the removal of relevant heavy metals such as silver (Ag+), copper (Cu2+), and cobalt (Co2+). The adsorption data of Ag+, Cu2+, ...
Adsorbents for glyphosate removal in contaminated waters: a review
(Corporación Universidad de la Costa, 2020)
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 ...
Preparation of activated carbon from the residues of the mushroom (Agaricus bisporus) production chain for the adsorption of the 2,4-dichlorophenoxyacetic herbicide
(Corporación Universidad de la Costa, 2021)
The production of the edible mushroom Agaricus bisporus occurs on a world scale, where tons are constantly produced. At the same time, this production generates a large amount of waste that needs to be adequately conditioned. ...
Adsorption of atrazine herbicide from water by diospyros kaki fruit waste activated carbon
(Elsevier, 2021-11-10)
In this work, Diospyros kaki fruit waste was employed as a precursor material to develop a high surface area activated carbon, which efficiently removed the toxic herbicide atrazine (ATZ) from synthetic water solutions and ...
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 ...
Adsorptive potential of Zn–Al and Mg–Fe layered double hydroxides for the removal of 2–nitrophenol from aqueous solutions
(Universidad de la Costa, 2020-08)
Two layered double hydroxides (LDH) of the type Zn–Al and Mg–Fe were synthesized, characterized and used as adsorbents to uptake 2–nitrophenol (2–NP) from aqueous solutions. XRD, FTIR, SEM, EDS, AFM and N2 adsorption/desorption ...
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 ...
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 ...
Evaluation of electrolytic reactor configuration for the regeneration of granular activated carbon saturated with methylene blue
(Corporación Universidad de la Costa, 2020-05-27)
The performance of an electrochemical process for the regeneration of granular activated carbon (GAC) was
evaluated using boron-doped diamond (BDD) anodes. Three different configurations were tested in the reactor:
fluidized ...
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). ...
