Catalytic spectrophotometric determination of trace Mo(vi) in milk-based beverages in the presence of bromophenol blue and H₂O₂ using SDS as a sensitizer

Abstract

A simple and low-cost catalytic spectrophotometric method using sodium dodecyl sulfate (SDS) as a sensitivity-improving surfactant to detect low levels of Mo(vi) in beverage matrices was developed.

Spectrophotometric Determination of Molybdenum(VI) as a Ternary Complex with 4-Nitrocatechol and Benzalkonium Chloride

“…Various techniques have been used for the determination of molybdenum in environmental and industrial samples, e.g., inductively coupled plasma mass spectrometry, Molecules 2022, 27, 1217 2 of 13 inductively coupled plasma optical emission spectrometry, electrothermal atomic absorption spectrometry, and spectrophotometry [10][11][12][13]. Spectrophotometry is a simple, cheap, convenient, and mature analytical technique [14][15][16]. It can be easily combined with extraction methods [17][18][19][20][21][22][23] to improve analytical performance.…”
