Extraction and separation of Vanadium (V) in Environmental Samples and Air Based on Bimodal Mesoporous Nano Material

In this study we investigated the enrichment ability of bimodal mesoporous nano material (UVNM-7) as a sorbent for vanadium separation and extraction in air and environment samples by flame atomic absorption spectrometry (F-AAS). In liquid-solid phase gas extraction (L-SPGE) based on UVNM-7, parameters influencing on the vanadium recoveries were optimized. Under optimal conditions, the vanadium exhibited a good linearity(R2=0.9995) over the concentration range 10–200 μgL-1. The detection limit (LOD) and precision (RSD) of the proposed method were 3.3 μg L-1 and less than % 5, respectively. Validation of methodology was confirmed by standard reference material and ET-AAS.
