Abstract
The extraction of indium complexes with 4-(2-pyridylazo)- resorcinol (PAR = H2R) was investigated and the nature of the complex species present in the organic and aqueous phases was' studied. From the several complex species present in the aqueous acetate solution at pH 6 only one anionic rlnR2r species was efficiently extract ed by tetraphenyphosphonium chloride as fPh4Pl rlnR21 associate
