    Flocculation in mixtures of cationic polyelectrolytes

    2003-12-01· For a mixture of J12 at 0.5 g l −1 and SLES at 30 mM, it is found, from Fig. 14, that b=0.54 s −1 and τ 0 =0.073. From Eq. (12) this gives a value for N o of 6.1×10 17 m −3, which is a minimum value. Indeed, if the flocculation is reaction limited, then k is lower and N 0 would be higher.
