Synthesis and sorption performance of highly specific imprinted particles for the direct recovery of carminic acid
(Elsevier, 2012-09)
Carminic acid (CA) is a colorant of natural origin, which is demanded by the food, cosmetic, and pharmaceutical industries. In this work, a selective finite bath process was developed based on the utilization of molecularly ...
Agricultural biomass/waste as adsorbents for toxic metal decontamination of aqueous solutions
(Elsevier Science, 2019-12-01)
Toxic metals can be present in the environment, causing negative effects on the ecosystem and human health. Although several technologies have been used for decontamination purposes, biosorption is an environmentally ...
Hexavalent chromium removal in contaminated water using reticulated chitosan micro/nanoparticles from seafood processing wastes
(Elsevier, 2015-07)
Chitosan particles (CH) were obtained from seafood processing wastes (shrimp shells) and physicochemically characterized; deacetylation degree of CH was measured by Infrared Spectroscopy (FTIR) and potentiometric titration; ...
Improvement of Paper Properties of Recycled Unbleached Softwood Kraft Pulps by Poly(Allylamine Hydrochloride)
(North Carolina State University. Department of Forest Biomaterials, 2011-01)
Polyelectrolytes containing amine functional groups such as PAH (poly(allylamine hydrochloride)) can be useful, under certain conditions, for improving paper strength. In this work, the charge density of PAH was determined ...
Legume Seeds Treated by High Hydrostatic Pressure: Effect on Functional Properties of Flours
(Springer, 2019-12)
Pigeon pea (PP), cowpea (CU), dolichos bean (DB), and jack bean (JB) are legumes that constitute the daily diet in many countries. Legumes are a good source of proteins, carbohydrates, and minerals. Considering that legumes ...
Linear algebra based controller design applied to a bench-scale o enological alcoholicfermentation
(Elsevier, 2014-04)
This work presents a controller design for a non-isothermal alcoholic fermentation to produce wines in a bench-scale bioreactor. The main controller objective is that the system tracks an optimal operation trajectory to ...
On the universal bahavior of sorption isotherms in disordered mesoporous solids
(Elsevier Science, 2004-07)
Adsorption–desorption isotherms in disordered mesoporous solids, described by the Dual Site-Bond Model, are obtained through Monte Carlo simulations and their behavior is correlated to the topological properties of the ...
Adsorption of peroxidase from Raphanus sativus L onto alginate-guar gum matrix: Kinetic, equilibrium and thermodynamic analysis
(Multi-Science Publishing, 2016-07)
This work explores the kinetics, equilibrium and thermodynamics of peroxidase adsorption onto spherical guar gum-alginate matrices. The effect of contact time, solution pH, initial protein concentration and temperature was ...
The crystallization phenomenon on a modified phosphate glass interpreted through the correlation between the a.c. electrical behaviour and the non isothermal nucleation
(Elsevier Science, 2021-04)
The electrical behavior of a bismuth-phosphate glass lithium ion conductor is studied in a very wide temperature range, from 39 K to 843 K, encompassing the glassy state, passing through the glass transition temperature, ...
Barrier properties and mechanical strength of bio-renewable, heat-sealable films based on gelatin, glycerol and soybean oil for sustainable food packaging
(Elsevier Science, 2018-04)
In this work we studied the mass transfer of renewable films based on gelatin (Ge), glycerol (Gly) and epoxidized soybean oil (ESO) for application in food packaging. Films were tested for water vapor absorption and diffusion ...
