Stanovení uranu pomocí ICP-OES při využití a neviužití prekoncentrace na makroporézních sorbentech The echelle based ICP spectrometer at 27.12 MHz, with power output 1.35 kW, Meinhard concentric nebuliser and CID detector is used for the determination of U. Linear calibration plots for 0.1-50 ppm U(IV) are in solutions containing 1-3% HNO3 for 385.958 and 409,014 nm. The slope of the plot decreases with the increasing concentration of HNO3 but increases in the presence of 4-(2-pyridylazo)resorcinol (PAR) by 10%. 3 x 10-3 M surfactants such as Septonex, Brij 35 and dodecylsulphate considerably increase the sensitivity of the determination of U. The detection limits are XD =1,26, XD =3,69 (Graham), XDm = 1,13 (Miller) or 0,30 ppm (IUPAC). No interferences at 1-3 ppm U were observed for 100:1 NO3-, Cl-, SO42-, SiO32- , NH4+, Na, K, Ca, Mg, Al 10:1 multicomponent containing Br-, Cl, Br-, SO42-, PO43-and Cd, Co, Cr, Cu, Mn, Pb, V, Zn in the absence or presence of internal standard Y (1ppm) except of Fe3+ for which the interfering signal 10:1 excess decreases only by 50% in the presence of Y.
