Use of carbon from the agricultural industry for the synthesis of catalysts destined to oxyanions removal from water.

Remediation of water contaminated with oxyanions is of great importance due to the toxicity and environmental persistence of these chemical species. The present work describes the elimination of different oxyanions in water using catalysts supported on active carbon obtained from an agricultural residue (peanut shells, C) and active commercial carbon (C) in order to compare their structural and catalytic properties. The synthesized C and C were fully characterized by surface analysis, TGA, TPR, SEM-EDX, FT-IR, and TEM.
