Removal of Pyrethrin from Aqueous Effluents by Adsorptive Micellar Flocculation

Table 1

Dependence of mass of micellar floc generated, residual pyrethrin equilibrium concentration, and equilibrium amount of pyrethrin adsorbed onto micellar floc on the initial concentration of aluminium sulphate and SDS solutions.
