摘要：
Extremely effective adsorbants are provided for removing color precursors from detergent range alkyl benzenes prior to sulfonation. The adsorbers provided are specific crystalline zeolites in a silica alumina matrix and bauxite clay having at least one material selected from the group consisting of ferric oxide, titanium dioxide and zirconium oxide which is activated by sulfuric acid then calcined to provide the effective adsorbant.
