Abstract
Abstract In the presence of other rare earths, cerium is best identified with redox indicators. p-Sulfanilic acid is a fairly specific indicator for cerium(IV), giving a red coloration with more than 6 p.p.m. o-Tolidine and diphenylamine sulfonate can identify smaller amounts of cerium(IV), but many oxidants interfere.
