荧光镓试剂Lumogallion是测定铝、镓较灵敏的荧光试剂,亦是铟、钪、铌、钒等金属离子的比色试剂,它在形成金属螯合物的过程中,有不同反应速率、由于离子选择电极能较快地响应离子活度的变化,因此用离子选择电极作动力学分析有其优越性。本文提出以荧光镓试剂作为活性物质制备对荧光镓试剂响应的离子选择电极,并详尽讨论了用动力学方法测定镓的条件。其测定下限可达0.005μg Ga/ml。
Fluorescent Gallium reagent Lumogallion is a relatively sensitive fluorescent reagent for the determination of aluminum and gallium. It is also a colorimetric reagent for metal ions such as indium, scandium, niobium and vanadium and has different reaction rates in the process of forming metal chelates. Since ions Electrode selection electrode can respond faster to changes in ion activity, so the use of ion selective electrode kinetic analysis has its advantages. In this paper, we propose a method of preparing gallium arsenide (GaAs) reactant with gallium arsenide (GaPb) as an active material and discuss the kinetic method for the determination of gallium. The determination of up to 0.005μg Ga / ml.
