【摘要】 <正> Ga³⁺与Al³⁺两者离子半径相近,化学性质类似,因此镓是金属铝中常见的杂质之一。荧光法是金属铝中微量镓测定的常用方法。应用表面活性剂的,见于镓-荧光镓（或其同系物）测定体系。8羟基喹啉（Oxine）曾用于硅酸岩中微量镓的萃取-荧光测定。本文研究了Ga³⁺-Oxine-表面活性剂体系荧光测定的合适条件,并应用于金属铝箔中微量镓的测定。更多还原

【Abstract】 A Fluorometric method for the determination of gallium with Ga3+ Oxine CTMAB system has been presented and applied to determine the content of gallium in aluminium foil. The method is four times more sensitive than the Ga3+ Oxine system and can be used in the concentration range of 0.5-900 ng Ga3+/ml with an accuracy of 4%.更多还原
