Preconcentration of Fe, Mn, Cu, Zn, Cd, Pb, V, Mo, Ni, Co, Cr, Tl, Ga, Au, U Hg, Se, As, Sn, Sb, Bi, and Te from saline water is described using multielement chelation with ammonium pyrrolidinedithiocarbamate extracted into chloroform. Extract residues were taken up in dilute nitric acid solution for analysis by simultaneous multielement inductively coupled plasma optical emission spectrometry (ICP-OES). Recovery percentages of elements at low microgram per liter levels in spiked saline samples ranged from 92 to 102%. Saline agricultural drainage and evaporation pond water samples from the San Joaquin Valley, CA, were analyzed by this method. In the case of U, the accuracy of the combined procedure was confirmed by an independent method.
