When we think in scientists, we remember scientic men. What about scientic women? In ancient times women had been considered by men for homework, without right to study at the university. In the beginning Hypatia from Alejandria was a pioneer scienti

An automatic procedure for the determination of nitroprusside has been developed. It is based on the strong quenching effect of the nitroprusside on the photochemical reaction between phloxin and ethylenediaminetetraacetic acid. The proposed flow-inj

The sensitizing effect of riboflavin (RF) and riboflavin 5′-phosphate (FMN) on the photo-oxidation of dianisidine was studied. The rate of the photochemical reaction was monitored spectrophotometrically at 460 nm. The method allows the determinatio

A new approach for the sensitive determination of oxalate was developed. Iron(II) generated in the photochemical decomposition of iron(III)-oxalate complex was measured by its catalysis of the chemiluminescent luminol reaction in the absence of added
