The flocculating efficiency of two cationic polyelectrolytes with quaternary ammonium salt groups in the main chain, with different branching degrees, on a bentonitic clay suspension, in comparison with polyacrylamide (PAM) was followed. The cationic polymer with a smaller branching degree operated similar to PAM. In both cases a purification of 100% was achieved. When the cationic polymer with a higher branching degree was used, a stabilization effect on the suspension was observed. The flocculating activity of the mixtures of the cationic polymer and polyacrylamide was also studied. |
