Abstract
An acid-activated decolourizing clay is prepared by treating an acid-activatable subbentonite clay, i.e. the calcium and magnesium sub-bentonites, with from 15 to 50 dosage (i.e. from 15 to 50 weight per cent of the clay) of hydrogen cloride in aqueous solution at a temperature above 80 DEG C., wherein said hydrogen chloride is present in said solution in a concentration of from 5 to 25% with respect to aqueous components, washing said treated clay with water until substantially free of chlorides and treating the washed clay with from 1 to 20 dosage of sulphuric or phosphoric acid at a temperature below 50 DEG C., the concentration of the acid with respect to the aqueous components varying from 1/2 to 5%, to remove the residual chlorides, removing excess acid from the clay, and drying the product wherein the clay temperature does not exceed 100 DEG C.
