Application of an Activated Carbon‐Based Support for Magnetic Solid Phase Extraction Followed by Spectrophotometric Determination of Tartrazine in Commercial Beverages

International Journal of Analytical Chemistry, Volume 2015, Issue 1, 2015., 2015
A method is presented for magnetic solid phase extraction of tartrazine from nonalcoholic beverages. The method involves the extraction and clean‐up by activated carbon covered with magnetite dispersed in the sample, followed by the magnetic isolation and desorption of the analyte by basified methanol.

Evaluation of Natural Materials as Exogenous Carbon Sources for Biological Treatment of Low Carbon‐to‐Nitrogen Wastewater

BioMed Research International, Volume 2015, Issue 1, 2015., 2015
In the bacterial processes involved in the mitigation of nitrogen pollution, an adequately high carbon‐to‐nitrogen (C : N) ratio is key to sustain denitrification. We evaluated three natural materials (woodchips, barley grains, and peanut shells) as carbon sources for low C : N wastewater.

Seasonal Changes of Fish Assemblages in a Subtropical Lagoon in the SE Gulf of California

The Scientific World Journal, Volume 2014, Issue 1, 2014., 2014
The composition and seasonal changes of the fish assemblage in a coastal lagoon system in southeastern Gulf of California were assessed from December 2001 to July 2005. A total of 20,877 organisms belonging to 191 species and 47 families were analyzed. We determined that almost all the species inhabiting the system were found; however some rare species

Main Characteristics of Mexico City Local Wind Events during the MILAGRO 2006 Campaign within a Meso‐β Scale Lattice Wind Modeling Approach

International Scholarly Research Notices, Volume 2013, Issue 1, 2013., 2013
A characterization of local wind events in Mexico City, which occurred during MILAGRO campaign, was carried out within the framework of a lattice wind modeling approach at a meso‐β scale. Mexico City was modeled as a 2D lattice domain with a given number of identical cells. Local wind conditions at any cell were described by a state variable defined by

Corrosion Behavior of Fe40Al Alloy with Additions of Ti, Ag, and Cr in Molten KCl + ZnCl2

International Journal of Corrosion, Volume 2012, Issue 1, 2012., 2012
The effect of 2.5 at.% Cr, Ti, and Ag on the corrosion behavior of Fe40Al intermetallic alloy in KCl‐ZnCl2 (1 : 1 M) at 670°C has been evaluated by using electrochemical techniques. Techniques included potentiodynamic polarization curves, linear polarization resistance (LPR), and electrochemical impedance spectroscopy (EIS) measurements.
