Replacement Extraction Chromatographic Separation and Preconcentration of Trace Gallium in Ores
【摘要】 本文提出以二乙基二硫代胺基甲酸铋Bi(DDC)8为固定相,硅胶为载体,以HAc—NaAc(pH=3)缓冲液为上柱液并淋洗杂质离子,用0.5M的盐酸溶液洗脱镓,以罗丹明B分光光度法测定。
【Abstract】 A highly selective rapid separation procedure for galliun has been developed. It is based on the extraction chromatography of gallium from HAc-NaAc(pH=3) solution using bismuth dithyldithiocarbamate as replacement extractant. 0.5M HCl is chosen as eluent for the elution of impuritions. The separation has been applied to the determination of trace gallium in ores by spectrophotometry.
