[The photocolorimetric determination of reducing agents using sodium metavanadate as reagent].
The oxidative properties of Vv can be used in the photocolorimetric determination of those reducers which give no other reactions with vanadium ions-penta and tetravalent. Two determination scales of the reducers were elaborated and the isoniazide hydrazide from tablets was dosed with satisfactory results.
