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.

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
