四羟基蒽醌法测定镓的干扰离子可用强硷型阴离子交换树脂除去,效果与乙醚萃取法一致,而测定矿石中镓含量较为简便迅速.

The separation of interfering ions in the quinalizarin colorimetric determination of gallium by means of anion exchanger (Ⅰonaustauscher Ⅲ, Cl-form, strongly basic anion exchanger) was examined. Procedures for the determination of gallium in bauxite,alunite, galena and sphalerite have been devised. The results found are very close to those obtained with the ether extraction method.
