The Applicability of Cellulose - Tara Gum Composite Hydrogels as Dye Capture Adsorbents
(Springer Science and Business Media Deutschland GmbH, 2022)
Acceso restringido
There is a growing interest in using naturally derived materials to generate adsorbent materials that can improve water quality by removing industrially derived pollutants such as dyes. In this work, composite beads were ...
Ultraviolet concentration factor of a truncated compound parabolic concentrator under different weather conditions
(Pleiades Publishing, 2020)
Acceso restringido
This study presents the results of ultraviolet radiation measurement in a truncated compound parabolic concentrator. The measurements were performed by using of a portable ultraviolet sensor both inside and outside the ...
TiO2:Cex onto Al Clays for Photocatalytic Solar Water Disinfection
(Hindawi, 2020)
Acceso abierto
A novel methodology was employed to prepare new nanocomposites with photocatalytic properties based on Ce-doped TiO2 nanoparticles arranged over a layered silicate. The catalysts were porous materials formed by exfoliated ...
Cellulose Microfibres Obtained from Agro-Industrial Tara Waste for Dye Adsorption in Water
(Springer, 2020)
Acceso restringido
Microfibres of cellulose were extracted from tara residues (TR), obtained after the production process, and used to remove dyes in aqueous solution. Caesalpinia spinosa (Molina) Kuntze or Tara spinosa, commonly known as ...
Treatment of irrigation water infested with nematodes using a solar photoreactor
(Desalination Publications, 2020)
Acceso restringido
The objective of this study was to assess the efficacy of the disinfection of irrigation water loaded with the plant-parasitic nematode Meloidogyne incognita using a solar photoreactor. The photoreactor was comprised of a ...
Elimination of Escherichia coli in Water Using Cobalt Ferrite Nanoparticles: Laboratory and Pilot Plant Experiments
(Multidisciplinary Digital Publishing Institute, 2019)
Acceso abierto
This paper focuses on the synthesis of cobalt ferrite nanoparticles by the sol–gel method
and their photocatalytic activity to eliminate bacteria in aqueous media at two di erent scales: in a
laboratory reactor and a ...
ZnO (Ag-N) Nanorods Films Optimized for Photocatalytic Water Purification
(Multidisciplinary Digital Publishing Institute, 2019)
Acceso abierto
ZnO nanorods (NRs) films, nitrogen-doped (ZnO:N), and ZnO doped with nitrogen and decorated with silver nanostructures (ZnO:N-Ag) NRs films were vertically supported on undoped and N doped ZnO seed layers by a wet chemical ...
Adsorption of antipyrine by activated carbons from FeCl3-activation of Tara gum
(Elsevier BV, 2018)
Acceso restringido
Activated carbons were synthesized by FeCl3-activation of Tara gum at different temperatures (400–1000 °C).
The activating agent and the precursor were physically mixed at different ratios (r= FeCl3:precursor,
0.5–3.0 ...
Study of the mechanical and energetic properties of pellets produce from agricultural biomass of quinoa, beans, oat, cattail and wheat
(Springer, 2017)
Acceso restringido
The lack of conventional fuels in rural areas in Peru drives people to burn agricultural wastes that are used as fuel. Burning these wastes produce a large amount of gaseous pollutants that harm the health of ...
Synthesis and Characterization of ZnO Nanorod Films on PET for Photocatalytic Disinfection of Water
(Science & Technology Network, Inc., 2015)
Acceso abierto
ZnO nanorods (ZnO NRs) were grown on ZnO seeded polyethylene tert-phtalate (PET) substrates obtained from
recycled soda bottles at low temperatures (90 °C) from Zn2+ precursors in alkaline aqueous solution. The ZnO
seeds ...
