FIELD: chemistry.
SUBSTANCE: invention relates to a method of increasing utilisation factor of silver during adsorption and removal of decyl iodide from acetic acid which contains decyl iodide as an impurity, by passing acetic acid through a packed layer of a cation-exchange resin at temperature 50°C or lower, where the cation-exchange resin is a macroporous-type polystyrene resin with average particle size ranging from 0.3 to 0.6 mm and average pore size from 15 to 28 nm, and where the resin has sulpho groups, and silver occupies 40-60% of the active sites of sulpho groups.
EFFECT: high utilisation factor of silver during adsorption and removal of decyl iodide from acetic acid.
