The chromatographic
behaviour of molibdenic heteropolyacids of phosphorus and silicon in ion-pair PR HPLC
Abstract
The chromatographic behaviour of molibdosilicon (MSA) and molibdophosporus (MPA) acids on
octadecylsilica gel (column 150x4.6 mm) was investigated at using eluents
containing tetrabuyilammonium bromid (TBAB) as ion-pair reagent. Acetic buffer,
sulfuric and chloric acids were added in eluents as sources of protons. The
optimum chromatographic conditions for simultaneous determination MSA and MPA
are: the eluent - 60% acetonitril, 10% acetic buffer and 0,8-1,2 mM tetrabutylammonium
bromid, detection wave - 310 nm.
