Four adsorbents with chemically bounded aniline radicals on silica gel surface of concentration 2.94; 5.86; 6.47 and 7.81 mymole/m(2) were prepared. On packed chromatographic column with unmodified silica gel Si 100 and obtained adsorbents the retention times of aliphatic (C6-C12) and aromatic (benzene, toluene and m-xylene) hydrocarbons and polar organic compounds (chloroform, ethylene chloride, chlorobenzene, p-chlorotoluene and ethyl benzene) were measured. Retention times, obtained on column with packing of the highest concentration of the bounded phase, were shorter than those on column with unmodified silica gel Si 100. Thus, there exists a possibility of optimization of retention of chemical compounds by change of their phase concentration on the support surface.
