Characterization,AcidActivation,andBleaching

Bleaching clays normally contain 10–18% moisture. If the clay is completely dried prior to use, its structure col-lapses, causing reduction in the bleaching power because of decreased surface area. In addition to these, adsorptive ca-pacity of acid activated clay is reduced if clay is added to hot oil.
