近年来陆续有些镓的催化极谱研究报导,文献提出在IN氯化钾和6·10~(-3)M五棓子酸底液中(pH=3),用示波极谱测定镓.文献研究了镓在水杨酸或对氨基水杨酸中催化电流的机理.文献应用脉冲极谱测定茜素红—S与镓的催化电流.此外文献也曾提出过在0.1N高氯酸,0.5M硫氰酸铵,5·10~(-3)M铜铁试剂底液中镓有良好的催化波,E_p为-0.63伏.综上所述,镓与含有羟基的有机化合物在滴汞电极上可能找到灵敏的催化波.我们曾以乙氯乙酸、
In recent years, some studies have been reported on the catalytic polarography of gallium. The literature proposes the determination of gallium by oscillopolarography in IN KCl and 6.10 ~ (-3) M pentanoic acid bottom solution (pH = 3). The mechanism of gallium catalytic current in salicylic acid or p-aminosalicylic acid has been studied in literature.Pulse polarography was used to determine the catalytic current of alizarin red-S and gallium.In addition, 0.5M ammonium thiocyanate, 5.10 ~ (-3) M copper and iron reagent base solution of gallium has a good catalytic wave, E_p -0.63 V. In summary, gallium and hydroxyl-containing organic compounds in the drop mercury The electrode may find a sensitive catalysis wave.We used to chloroacetic acid,
