The investigation of a novel indicator system for trace determination and speciation of selenium in natural water samples by kinetic spectrophotometric detection
A novel catalytic kinetic method is proposed for the determination of Se(IV), Se(VI) and total inorganic selenium in water based on the catalytic effect of Se(IV) on the reduction of bromate by p-nitrophenylhydrazine at ...
Speciative determination of total V and dissolved inorganic vanadium species in environmental waters by catalytic–kinetic spectrophotometric method
(Elsevier B.V., 2017)
A kinetic determination of V(V) as a catalyst was spectrophotometrically performed by using the indicator reaction of Gallamine blue (GB+) and bromate at pH 2.0. The reaction was followed by measuring absorbance change for ...
Catalytic spectrophotometry for the determination of manganese at trace levels by a novel indicator reaction
A new kinetic spectrophotometric method is developed for the measurement of Mn(II) in natural water samples. The method is based on the catalytic effect of Mn(II) with the oxidation of Gallocyanin by KIO4 using nitrilotriacetic ...
