Separation and gravimetric determination of cerium and lanthanum with N- m-tolyl- m-nitrobenzohydroxamic acid

Cerium and lanthanum were determined gravimetrically by selective precipitation with N- m-tolyl- m-nitrobenzohydroxamic acid and separated from several metal ions such as Ag +, Be 2+ , Pb 2+ , Mn 2+ , Cu 2+, Zn 2+ , Cd 2+ , Hg 2+ , Pd 2+ , Ga 3+ A1 3+ , Bi 3+ , Sb 3+, Sn 4+, Ce 3+ , Pr 3+ , Nd 3+ ,...

Description
Summary:Cerium and lanthanum were determined gravimetrically by selective precipitation with N- m-tolyl- m-nitrobenzohydroxamic acid and separated from several metal ions such as Ag +, Be 2+ , Pb 2+ , Mn 2+ , Cu 2+, Zn 2+ , Cd 2+ , Hg 2+ , Pd 2+ , Ga 3+ A1 3+ , Bi 3+ , Sb 3+, Sn 4+, Ce 3+ , Pr 3+ , Nd 3+ , Ti 4+, Zr 4+, Th 4+, V 5+ , Mo 6+ and U 6+ . The precipitates were weighted directly after drying at 110°. The analytical results indicated the composition of the complexes to be (C 14H 11N 2O 4) n M.
