Miss Cabrera studied chemical engineer with Master in Analysis of Industrial Systems for the University of Guadalajara, experience in productive processes of beverages industry as well as implementation of quality systems and certification under the ISO 9000, worked in develop for yeasts, fermentation and process optimization in the tequila industry. Additional she works as process engineer in the automotive industry taking part in project transferations, optimization, development and implementation of new technologies across his formation as Green Belt six sigma. Nowadays she is in studying PhD in Water and Energy in Tonalá's University Center by Universidad de Guadalajara.
This work studied the obtaintion of a functionalized carbon in a single stage using green leaves of Agave Tequilana Weber var. blue by hydrothermal carbonization (HTC) and a chemical activation with sulfurous acid. The variables studied were the treatment time (8, 16, 24 h) and the sulfonic acid concentration (0, 1.5, 3.0, 4.5% w/v). The functionalized carbon was morphologically characterized by the techniques SEM, TEM, DRX and BET and chemically by the techniques FTIR, 13C, NMR of solids, XPS and elemental analysis, to determine the level of functionalization that has been achieved by this stage. A potential application of functionalized carbon is the adsorption of heavy metals in residual solutions; the research focused on the adsorption of hexavalent chromium (Cr+6) at different pH and Cr+6 concentrations were determined by experimentally. With these studies, adsorption kinetics was made using the sample CF-8H-4.5 at pH=2.0 and 50 ppm of Cr+6. This carbon had an uptake of 19.50 mg Cr+6 / g CF-8H-4.5, a quite promising result and better than others carbons of this study.
Audience take away:
• This work shows how to obtain an hydrochar in one step
• Those hydrochars can be use as a heavy metal removal from water.
