抄録
Fundamental experiments were carried out to determine the micro-amounts of aluminium by spectrophotometry, using chrome azurol S, a reagent used in complexometric titration of copper, zirconium and aluminium. By this new method, most part of the iron content was separated by methyl isobutyl ketone and the remaining iron and copper was masked by thioglycolic acid and after adjusting the pH to 5.6∼6.8, the absorbance of the aluminium chelate compound was measured at 550 mμ. This method requires only a few reagents and does not need warming for promoting coloration, nor does it require the protecting colloid in contrast with the aluminon method. Since this reagent presents very sensitive color reaction even in micro-amounts of aluminium, it can be determined in 0.002 to 0.1 per cent with good reproducibility.
