Abstract
Problem of nitrophenols group analysis as well as separation to individuals is still attracting attention of research and practicing chemists, environmental chemists and the others. Chromatographic behaviour in RPHPLC systems expressed by such parameters as retention time, sorption capacity, selectivity and/or elution order was studied for group of 8 nitrophenols: 2,4,6-trinitrophenol, 2-nitrophenol, 3-nitrophenol, 4-nitrophenol, 2,4-dinitrophenol, 2,5-dinitrophenol, 2,6-dinitrophenol and 4-nitro-3-cresol. Condition for baseline separation of almost all of these nitrophenols on Separon SGX C18 were chosen. Sorption capacities were tested for 4 different RP materials. The data will be used for devising of Solid Phase Extraction (SPE) and/or column switching schema in RPHPLC sample pretreatment.
