FIELD: chemistry.
SUBSTANCE: invention relates to biotechnology. Disclosed is a method of purifying an aqueous solution containing a nickel salt from nickel ions. The method involves contacting an aqueous solution containing 20 mg Ni2+/l with 0.2 g suspension of a homogenised culture per 1 l solution. The suspension has the following composition of dominant types of cyanobacteria: Phormidium ambiguum (Jom.), Phormidium boryanum (Kutz.), Leptolyngbya foveolarum (Rabenhor stex Gom), Plectonema boryanum (Gom.f.boryanum). Contacting is carried out for 1-3 hours.
EFFECT: invention enables to purify an aqueous solution from divalent nickel ions to concentration close to or lower than the maximum allowable concentration of 0,1 mg/l.
