• Extraction behavior of indium has been investigated with 3-hydroxy-2-methyl-1-phenyl-4-pyridone (HMPP) at 25±0.1 °C and an ionic strength of 0.2. The values of the proton-dissociation constants, p<I>K</I><SUB>a1</SUB> and p<I>K</I><SUB>a2</SUB>, of HMPP were determined spectrophotometrically to be 3.02 and 9.56. The value of the partition coefficient, log<I>K</I><SUB>D</SUB>, of HMPP between 1,2-dichloroethane and water was determined to be 1.35. Indium(III) was extracted into 1,2-dichloroethane by forming a 1 : 3 (metal : ligand) complex with HMPP. The extraction constant, <I>K</I><SUB>ex</SUB>, the overall formation constant, β<SUB>3</SUB>, and the distribution constant, <I>K</I><SUB>DC</SUB>, of the indium(III)–HMPP complex were determined, their values being as follows: log<I>K</I><SUB>ex</SUB>=2.16, logβ<SUB>3</SUB>=32.63, and log<I>K</I><SUB>DC</SUB>=2.26.
