N,N-二仲辛基乙酰胺萃取原子吸收光谱法测定矿石中金

Determination of Gold in Ores by Atomic Absorption Spectrometry After Extraction with N,N-Di-Sec-Octylacetamide

介绍在5％HCl介质中,用DOAA的乙酸丁酯萃取矿石中的微量金,并以空气-乙炔火焰原子吸收法直接在有机相中进行测定。

Trace gold is extracted with DOAA into butylacetate and determined by atomic absorption spe-ctrometry with air-acetylene flame. Within the range of 0-60g the amount of gold verstts absorb-ance exhibits a linear relationship. In the determination of gold, no significant interference is caused by Fe, Ni, Ca, Pt, Ga etc.
