"STABILISED SOLUTIONS" An aqueous solution of a cationic flocculant containing less than 10 grams per litre of the flocculant is stabilised by the addition of free acid in an amount sufficient to render a solution pH of from 1:5.5. The stabilised solutions can be stored without deterioration of the flocculating agent and are of value, particularly in the manufacture of titanium dioxide pigments. |
