FIELD: waste water treatment.
SUBSTANCE: method involves treating wastewater from potassium hexacyanoferrates: K3[Fe(CN)6] or K4[Fe(CN)6]. Polyelectrolyte microcapsules (PMCs) are added to water, obtained by layer-by-layer adsorption of oppositely charged polyelectrolytes polystyrene sulfonate (PSS) and polyallylamine (PAA) and having a shell composition: (PAA/PSS)3, or (PSS/PAA)3, or (PAA/PSS)2 /PAA, or (PSS/PAA)2 /PSS, carry out the sorption of K3[Fe(CN)6] or K4[Fe(CN)6] for no more than 15 minutes and remove PMCs from the water.
EFFECT: wastewater treatment from potassium hexacyanoferrates: K3[Fe(CN)6] or K4[Fe(CN)6].
