The Synthesis and evaluation of a chitosan-humic acid composite for the removal of atrazine from aqueous solutions
(2014)
Atrazine is an artificial organic herbicide scientifically known as 2-chloro-4-(ethylamino)-6- (isopropylamino)-s-triazine. It is commonly used in agriculture to control growth of unwanted weeds, by inhibiting its ...
Sorption of VOCs and PAHs onto recycled tire crumb rubber
(2011)
Sorption of Volatile Organic Compounds (VOCs) (ethylbenzene, toluene and xylene) and Poly Aromatic Hydrocarbons (PAHs) (acenaphthene, acenaphthylene and phenanthrene) by tire crumb rubber (TCR) and its main components were ...
Removal and speciation of oxyanions from aqueous solutions using Ca-Fe(III) alginate beads and dried sludge as adsorbents
(2013)
Oxyanions are highly soluble species, which are pH and redox dependant, and represent a toxic and hazardous species to humans and for the environment. Various remediation techniques have been applied such as: precipitati ...
Removal of the oxytetracycline antimicrobial from aqueous solution using waste tire crumb rubber
(2011)
As of today we face serious problems of pollution, of which one is the excess of antimicrobial compounds (e.g. Oxytetracycline, OTC) and another is the stockpiles of used tires. Our research project evaluated the sorption ...
Caracterización química de metabolitos aislados en un extracto con actividad antimicrobiana y antifúngica de la ascidia, Rhopalaea sp. Proveniente del área de Cuajiniquil, Guanacaste, Costa Rica
(2009)
Marine ecosystems have a very large amount of resources, most of them are still partially unknown, and few have been exploited for development of new industrial and toxicological products. The objective of this investigation ...
Optimization of biodiesel production process using recycled vegetable oil
(2010)
Petro diesel toxic emissions and its limited resources have created an interest for the
development of new energy resources, such as biodiesel. Biodiesel is traditionally produced
by a transesterification reaction between ...
Synthesis and evaluation of alginate coated magnetite nanoparticles for the removal of dyes from wastewater
(2020-12-11)
The discharge of wastewater from the dyeing industry is an environmental concern across the
world. These effluents are considered highly toxic since they contain high concentrations of synthetic
dyes, which are a great ...
Single-step processing of Cu and Ag nanocrystals and nanocomposites for antimicrobial applications
(2021-12-09)
Emerging and re-emerging pathogens pose a worldwide public health risk since they can cause severe infectious diseases, which are difficult to treat due to the ineffective action of traditional treatments. Furthermore, ...
