Abstract

Yttrium hydroxide quantitatively coprecipitated Be(II), Ti(IV), Cr(III), Mn(II), Fe(III), Co(II), Ni(II), Cu(II), Zn(II), Cd(II), and Pb(II) at pH 9.6 - 10.0 for seawater and pH 10.5 - 11.4 for a table-salt solution. The coprecipitated elements could be determined by inductively coupled plasma atomic emission spectrometry; yttrium was used as an internal standard element. The detection limits ranged from 0.0016 µg (Mn(II)) to 0.22 µg (Zn(II)) in 100 mL of sample solutions. The operation time required to separate 11 elements was approximately 30 min.
