[en] Conditions of group concentration of (Pd, Fe, Mn, Zn, Ca and other) element trace amounts by their coprecipitation on inorganic collectors (the Ca hydroxide, Fe and calcium carbonate) are studied. The possibility of microelement concentration by their coprecipitation on calcium carbonate with further atomic absorption determination of microelements is shown. The technique proposed is used to determine microelements in natural waters. The sensitivity equals 0.002-0.005 μg of microelements in 1 ml of the solution
