pH Indicators As Chemical Reagents for the Enhancement of Footwear Marks

Journal of Forensic Sciences, 1996
Abstract Enhancement of weak two-dimensional shoemarks is often necessary due to the poor image detail. Thiocyanate is regarded in the literature as the most effective reagent for the chemical enhancement of footwear marks. In this study we have examined the possibility of using pH indicators, Bromophenol Blue and Bromocresol Green, as ...

Ion-Selective Optode Nanospheres as Heterogeneous Indicator Reagents in Complexometric Titrations

Analytical Chemistry, 2015
Traditionally, optical titrations of inorganic ions are based on a rapid and visible color change at the end point with water-soluble organic dyes as indicators. Adequate selectivity is required for both the indicator and the complexing agent, which is often limited.

Metallofluorescent indicators as spray reagents for the in situ determination of organophosphorus pesticides on thin-layer chromatograms

Analytica Chimica Acta, 1972
Abstract Fluorescence-quenched solutions of palladium(II)-calcein and palladium(II)-calcein blue are shown to be sensitive spray reagents for the detection and in situ determination of organothiophosphorus insecticides on thin-layer chromatograms.

An examination of chlorpromazine hydrochloride as indicator and spectrophotometric reagent for the determination of molybdenum(V)

Analytica Chimica Acta, 1977
Abstract Chlorpromazine hydrochloride (CPA) has been tested as indicator in the titration of molybdenurn(V) with cerium(IV)sulphate at room temperature in sulphuric acid medium. It gives a sharp, reversible colour change from colourless to dark-red at the equivalence point.
