A multifunctional bi-phasic graphene oxide/chitosan paper for water treatment
(Elsevier, 2020)
A bi-phasic and water-stable GO paper was developed based on a simple casting method and the addition of a chitosan (CH) coating layer. While pure GO paper re-dispersed after water immersion water becoming a powder, the ...
Evaluation of the kinetics of oxidation and removal of organic matter in the self-purification of a mountain river
(Universidad Nacional de Colombia (Sede Medellín). Facultad de Minas., 2015-05-01)
The study is based on the determination of the kinetic rates and assessment of self-purification of the Frio River, due to the uptake of organic load. The kinetic rates were calculated by applying differential and logarithmic ...
Tuning of metal oxides photocatalytic performance using Ag nanoparticles integration
(Elsevier, 2020)
Water contamination is increasingly an important issue in developing and under developed countries. The main cause of water contaminations are industrial dyes and toxic chemicals. Hence many technologies are being developed ...
Core–sheath nanofibrous membranes based on poly(acrylonitrile-butadiene-styrene), polyacrylonitrile, and zinc oxide nanoparticles for photoreduction of Cr(VI) ions in aqueous solutions
(John Wiley & Sons Inc, 2020-03)
This investigation addresses the design of a series of poly(acrylonitrile-butadiene-styrene)/polyacrylonitrile–zinc oxide(ABS/PAN–ZnO) membranes by coaxial electrospinning. In the first instance, an optimization of ABS and ...
