Malachite green removal using ionic flocculation

Abstract The use of ionic flocculation is proposed to remove malachite green (MG), in this case, from water. A surfactant with the polluted solution and calcium added. surfactant-calcium reaction forms a precipitate, which aggregates into flocs on agitation. adsorb MG, can then be removed by centrifugation. Ionic was assessed varying parameters including: MG concentrations, electrolyte content, pH, contact time, etc. isotherm adsorption kinetic models that best fit process are Langmuir pseudo-second-order models, respectively. removal efficiency 96% obtained at pH 9, concentration 1,400 mg L−1, 10 L−1 time minutes. has potential for pollutant removal.
