摘要:

For a selective spectrophotometric determination of gallium(III) without interference of aluminium(III), firstly, the color developments between gallium(III) and various chelating azo-dyes; 4(2-pyridylazo) resorcinol (PAR), 2-(5bromo-2-pyridylazo)-5-diethylaminophenol (5-Br.PADAP) in the presence or absence of surfactant alone; cationic-, anionic-, nonionic-surfactants or surfactant combination; cationic-nonionic-, anionic-nonionic-, cationic-anionic mixed surfactants, were systematically investigated.
