Spectrophotometric determination of gallium with Brilliant Green

Spectrophotometric determination of gallium(III) with rutin.

KINETIC SPECTROPHOTOMETRIC DETERMINATION OF MERCURY IN DIFFERENT MATERIALS BASED ON ITS INHIBITORY EFFECT ON THE BRILLIANT GREEN-SULFITE REACTION

A new kinetic method for the determination of Hg(II) based on its inhibitory effect on the Brilliant green-sulfite reaction at pH 6.5 is proposed. The reaction is followed spectrophotometrically at 615 nm by measuring the change in absorbance at the fixed time of 3.5 min after the initiation of the reaction. Both the influence of the reaction variables and the interference of many ions have...

Spectrophotometric determination of trace amount of malachite green from water with novel magnetic silica nanoparticles

A nano-hybrid based on polystyrene derivatives and magnetite was introduced as a new sorbent for pretreatment and determine the trace amount of malachite green from aqueous solution by spectrophotometry after preconcentration by solid phase extraction (SPE). UV–Vis spectrophotometer was used for determination of MG concentration after desorption of the dye by hydrochloric acid solution in the s...

Spectrophotometric and derivative spectrophotometric determination of aluminium with Hydroxynaphthol Blue.

The reaction of aluminium(III) with Hydroxynaphtol Blue (HNB) in aqueous media at apparent pH 5.5 results in a red complex that is stable for at least 4 hr. Beer's Law is obeyed up to 1.6 microg/ml of aluminium(III) with an apparent molar absorptivity of 1.66 x 10(4) l.mol(-1). cm(-1) at 569 nm. This paper proposes procedures for aluminium(III) determination by ordinary and first-derivative spe...
