The effect of some modifiers on the retention of aromatic hydrocarbons on untreated silica gel
- 13 Downloads
The retention parameters of benzene, naphthalene; anthracene and phenanthrene on untreated silica gel were determined in the presence of four modifiers: 1-methyl-2-pyrrolidone (MP), 4-formyl morpholine (FM), γ-butyrolactone (BL) and sulfolane (SF). Better column performance was found in the case of FM and MP only.
