FIELD: chemistry.
SUBSTANCE: invention relates to a porous fibre which can efficiently adsorb a removable target substance from the treated fluid, as well as to a cleaning column which includes said porous fibre. Porous fibre has a modified solid cross-section. Degree of modification of Do/Di in the solid fibre cross-section is 1.20–8.50, where Di is the diameter of the inscribed circle, and Do is the diameter of the circumscribed circle. Specific surface of the pores of the fibre is not less than 3 m2/g. Adsorbing material contains not less than 28 vol. % of porous fibre in form of fibre bundle. Cleaning column is formed by arrangement of adsorbing material in straight form in direction of plastic housing axis and by connection of inlet hole and outlet hole for processed fluid medium to both ends of plastic housing.
EFFECT: higher efficiency of adsorption of removed target substance from treated fluid medium.
