The Chemical, Mineralogical, Structural and Surface Properties of Selected Ugandan Clays and their Application in Bleaching Oil

For a long time, clays have been used to clarify mineral and vegetable oils (Nutting, 1933; Siddiqui, 1968). Whereas vegetable oils for human consumption are clarified using bleaching earths (Adekeye and Bale, 2008; Ajemba et al, 2012;Kamal et al, 2011; Mustapha et al, 2013; Patterson, 1992; Proctor, 1988; Salawudeen et al 2007; 2014; Taylor, 1984; Zchau, 1981), other oils can be clarified using peroxides.
