ACYLATION AND DISPERSIVE MICROEXTRACTION FOR CHROMATOGRAPHIC DETERMINATION OF DIPHENYLKETONES - article

The possibility of dispersive liquid phase microextraction and derivatization with acetic anhydride and GC/FID determination of benzophenones is shown. The parameters of derivatization and dispersive microextraction of 2 hydroxybenzophenone, benzophenone-3 and benzophenone-1 were optimized. The microextraction has been developed for GC/FID determination of benzophenones in natural waters and it has been examined by “add and found” method. The results of benzophenones determination showed good precision and repeatаbility.
