METHOD FOR DETERMINATION OF LEAD AND CADMIUM IN FOOD PRODUCTS OF PLANT ORIGIN

摘要

Method for atomic-absorption determination of lead and cadmium in food products of plant origin includes carbonization of sample at heating to 450 °C during 20 minutes, cooling of carbotizate obtained, weighing, milling, adding chemical modifier, implementation of stages of drying, purolisis, automation. As chemical modifier one uses solution of sodium diethyldithyocarbamate with concentration 0.1 mol/l. Solid carbonizate of foor product of plant origin is applied directly to surface of graphite rod of automizer of solid samples furnace-flame".
