The method is based on the complex formation of V(V) and Fe(III) with chromazurol S (CAS) in acidic media and in the presence of cetyltrimethylammonium bromide (CTAB) as a micellizing agent. Acidic media and the presence of a micellar system improve selectivity and sensitivity. Fe (III) and V (V) could be determined simultaneously in the range of 0.1-2 and 0.2-2 µg / mL, respectively, and with the ratio 1:20 to 10:1 Fe(III)/V(V) in the mixed samples. The proposed method was successfully applied to the simultaneous determination of Fe(III) and V(V) in tap, river, saliva and plasma samples.}, keywords = {Vanadium (V),Iron (III),H-point standard addition,spectroscopy}, url = {https://ijcce.ac.ir/article_6736.html}, eprint = {https://ijcce.ac.ir/article_6736_5e7fdea1d5187d399dee6f3136546afb.pdf} }
