FIELD: chemistry.
SUBSTANCE: invention relates to production of biologically active additives. What is presented is a method for preparing the triple chelate complex of the essential zinc microelement. Method involves mechanical mixing 2.8 g of lysine monohydrochloride, 2.7 g of ascorbic acid, 4.9 g of barium hydroxide, 4.5 g of zinc sulphate, 30 ml of distilled water, centrifuging the working solution at 3000 rpm for 5 minutes. Before centrifugation, the working solution is treated with ultrasonic radiation with the following parameter values: working solution insonification frequency is 20-39 kHz, ultrasonic radiation modulation frequency is 10-69 Hz, working solution insonification time is 11-22 minutes, relative power of ultrasonic radiation is 35-149 W/l.
EFFECT: invention enables to obtain a ternary chelate zinc complex with improved antioxidant properties.
