ANALYSIS OF SOME AROMATIC AMINES BY MEANS OF DERIVATIVE SPECTROPHOTOMETRY

ABSTRACT

Derivative spectrophotometry (DS) was applied for the determination of selected aromatic amines in two-compound mixtures. Following pairs were analysed: o- and m-toluidine, o- and p-toluidine, m- and p-toluidine; o- and m-phenylenediamine (PDA), o- and p-PDA, m- and p-PDA; p,p′-diaminodiphenylmethane (DADPMe) and p-toluidine. The developed method of DS was used as a complementary technique to HPLC with DAD detector as it allows the determination of compounds, which give a common peak in a chromatographic system.
