(a) Effect of concentration of OFX 0309 surfactant towards extraction efficiency of both triazine species. Conditions: 10 mg l−1 of triazine species, 2.0 M of Na2SO4, pH 5, 50°C. (b) Effect of volume of OFX 0309 surfactant towards extraction efficiency of both triazine species. Conditions: 10 mg l−1 of triazine species, 0.4 v/v% OFX 0309 surfactant, 2.0 M of Na2SO4, pH 5, 50°C.
