Papers impregnated with titanic tungstate have been used to chromatograph 52 cations in 45 aqueous and mixed solvents. Experimentally, a large number of complex cation separations have been achieved easily and rapidly—Au3+, Tl3+, Ag+, Mo6+, K+, Rb+, CS+, Ni2+, Sb2+, Bi3+, Be2+, and Tl+can be easily separated from numerous metal ions. Several quaternary, ternary, and binary separations have also been achieved, and some important separations are discussed.
