FIELD: various technological processes.
SUBSTANCE: invention relates to environmental protection and can be used to purify water from microplastics. Technical result is achieved due to use of activated biochar from bark of pine and spruce for water purification from microplastic, which, according to the invention, is made from woodworking industry wastes containing 50 wt.% of pine bark and 50 wt.% of spruce bark, subjected to pyrolysis at temperature of 475°C for three hours and activated with superheated water vapor, having specific surface area of 556–603 m2/g, for adsorption of microplastic from water.
EFFECT: use of biochar from wood processing wastes for water purification from microplastic.
