AMPEROMETRIC TITRATION OF NOBLE METALS WITH SOLUTIONS OF NITROGEN-SULPHUR-CONTAINING REAGENTS IN NON-AQUEOUS AND MIXED MEDIA

Abstract

The article shows the conditions and the possibility of amperometric titration of noble metals with 4methoxyphenylcarboxymethyldiethyldithiocarbamate (MFCMDETK) and 4- methoxyphenylcarboxymethyl-diethyldithiocarbazone solutions (MFCMDFDTK) in non-aqueous media (acetic acid, n-propanol, DMFA, DMSO) and their mixtures with background electrolytes having different acid-base properties. The methods of amperometric titration of micrograms of the quantities of noble metals ions in the presence of foreign ions containing ions
