| 摘 要： | 本文研究了铝电解质中氧化镓的测定方法，采用高温熔融样品，用三氯化钛还原Fe^3 等高价离子以消除干扰。在4．5－7.0mol/L盐酸介质中，使镓与丁基罗丹明B显色，以苯萃取，分光光度法测定。方法准确可靠，回收率在99.1%-102.2%之间，相对标准偏差为5.82%-6.26%。

| Abstract: | This paper studied the determination method of gallium oxide in aluminium electrolyte.The sample was fused by high temperature,and TiCl 3 was used to reduce Fe 3+ etc.so as to eliminate the disturbance.In the medium of hydrochloric acid of 4.5-7.0mol/L,gallium was colorated with butyl rhodamine B.This method is accurate and reliable.The recovery and RSD is in the range of 99.1%-102.2%,and 5.82%-6.26%,respectively. |
