FIELD: chemistry.
SUBSTANCE: invention can be used in medicine, in electronic and petrochemical industry. Colloid metal nanoparticles solution process involves dissolution of gold iodide or silver iodide in water or nonaqueous solvent, blowout of carbon (II) oxide gas through said solution followed by heating the solvent to temperature not exceeding 50°C or introduction of organic liquid not mixed with water or nonaqueous solvent. The organic liquid is tetrachloride carbon in amount 0.1 of solution volume and less.
EFFECT: higher purity of prepared colloid solution ensured by the absence of salt anion impurity.
