Vanadium finds applications in various industries, accurate
determination of vanadium levels ensures quality control and monitoring
vanadium levels in drinking water and air helps in public health. The
development of spectrophotometric determination using Metanil yellow dye
contributes to the advancement of analytical chemistry. The method quantifies
trace levels of vanadium in various samples and serves diverse societal needs,
including environmental protection, industrial quality control, public health,
scientific advancement, regulatory compliance, and resource management. A
simple, rapid, selective and sensitive method for the spectrophotometric
determination of microgram amount of Vanadium (V) utilizing the reaction of
Metanil yellow dye in 40% Ethyl Alcohol medium. Metanil yellow reacts with
Vanadium (V) instantaneously at room temperature in a slightly acidic medium.
The complex exhibits an absorption maximum at 512 nm of UV- visible
spectrophotometer with a molar absorptivity of 2.21 × 105 litre mol-1 cm-1. The
sensitivity is 4.52 n gm of Vanadium ml-1 and the optimum range for the
effective spectrophotometric determination is 0.05-0.41µg ml-1. A five-fold
molar excess of the dye is necessary for the full development of the colour
intensity. The influence of some common
ions is reported.
