A simple, rapid, and selective method has been developed for the separation and determination of Cr(VI) from Al(III), Cr(III), Mn(II), Fe(III), Co(II), Ni(II), Cu(II), Zn(II), Se(IV), Sr(II), Zr(IV), Cd(II), La(III), Ce(III), Hg(II), and U(VI). Separation was accomplished in 12.5 cm migration distance and 14 min migration time on titanic silicate ion-exchange plates with 0.4 M ammonium oxalate - 2.2 M aqueous ammonia, 1:1 (v/v), as mobile phase. Quantitative measurement of the separated zones of Cr(VI) was achieved by scanning densitometry at ? = 545 nm.
