Encapsulation of di-2-ethylhexylphosphoric acid was carried out by ionic complex of gelatine with cetyltrimonium bromide. Dispersity of obtained microcapsules at various extractant and oil phase contents was determined by optical microscopy and dynamic light scattering measurements. It was found that kinetic parameters and efficiency of iron removal from aqueous medium by encapsulated extractant is more attractive in comparison with the results of liquid or membrane extraction.
