FIELD: chemistry.SUBSTANCE: sorbent is obtained by mixing iron-containing wastes of metallurgical production with wastes of production of mineral fertilisers and anionic SAS, representing derivatives of fatty acids. Mixing is performed at temperature 60°C. Mixture is homogenised until homogenous state is achieved. Sorbent, containing, counted per element composition, wt %: calcium - 34, oxygen - 44, carbon - 13, iron - 8, hydrogen - 0.6, sodium - 0.4.EFFECT: invention makes it possible to use iron-containing wastes of metallurgical production and mineral fertilisers to obtain sorbent with higher sorption ability and lower water absorption.2 ex |
