FIELD: organic compounds technology and industrial ecology. ^ SUBSTANCE: target products can be used for preparing electrolytic copper coating electrolytes, for inhibiting equipment corrosion, as fungicides and agricultural copper microfertilizers, for antibacterial treatment of water, and for other purposes. Compounds of copper(II) with amino carboxylic acids are prepared via crystallization from aqueous solution prepared by mixing amino carboxylic acid or its alkaline metal salt with radioelectronic production waste, namely with spent solutions used for etching different circuit plates and containing, as chief components, copper(II), mineral acid, ammonium or cupric salt, ammonia, and ammonium salt. ^ EFFECT: reduced expenditures on preparation of target compounds, extended assortment of materials for preparation thereof, and enabled reuse of toxic radioelectronic production waste. ^ 13 cl, 5 ex
