近年来,镓已用来制成了砷化镓单晶和钆镓石榴石晶体等,己广泛应用于电子计算机、红外技术,微波通讯,激光和太阳能电池方面。 随着镓的广泛应用其分析测定技术日益发展,特别是近年来,微量镓的测定技术发展更快。五十年代初,H.O nishi和E.B.Sandell提出用乙醚可将镓从干扰元素中萃取出来,然后比色测定,但萃取率较低。后来有人提出用三分苯和一分乙醚混合萃取镓罗丹明B络合物能达到完全。笔者对影响镓萃取的因素进行了某些实验和探讨。
In recent years, gallium has been used to make GaAs single crystal and gadolinium gallium garnet crystals, has been widely used in electronic computers, infrared technology, microwave communications, lasers and solar cells. With the wide application of gallium, its analytical determination technology is developing day by day, especially in recent years, the determination of trace amounts of gallium has been developing rapidly. In the early 1950s, H.Onishi and E.B.Sandell proposed that gallium can be extracted from interfering elements with diethyl ether and then subjected to a colorimetric assay with a lower extraction rate. It was later proposed mixed with one-third of benzene and ether diethyl gallium rhodamine B complex can be achieved completely. The author of the factors that affect the gallium extraction of some experiments and discussions.
