Dissolved antimony is present in seawater at very low concentration levels, typical concentrations of Sb in unpolluted water samples are less than 1 µg L-1. Since the concentration of this element in water is very low, high sensitive analytical techniques are required, The system is based on retention of the analyte onto a micro-column filled with a novel mesoporous silica functionalized with [1,5 bis(di-2-pyridyl) methylene] thiocarbohydrazide placed in the injection valve of the FI manifold.   spa open access Antimonio Synthesis and characterization of a novel mesoporous silica funtionalized whith [1,5 bis (di-2-pyridyl) methylene thiocarbohydrazide] and its application as enrichment sorbent for determination of antimony by FI-HG-ETAAS conference output
