镓(Ⅲ)-芦丁极谱络合吸附波的研究
Polarographic Adsorptive Complex Wave of Gallium(Ⅲ)-Rutin
【摘要】 在(CH2)6N4-HCl缓冲底液中,获得了Ga(Ⅲ)-芦丁的络合物吸附催化前波,检出限达1.0×10-3mol/L。用其测定了以SiO2、Al2O3为基体的催化剂中的镓.研究了其电极过程机理。
【Abstract】 In (CH2)6N4-HCl buffer solution at pH 5, a sensitive adsorptive complex wave of Ga(Ⅱ)-rutin (Rt) was obtained by single-sweep Polarography. The detection limit is down to 1.0×10-8mol/L. The proposed method has been applied to the determination of gallium in catalyst. The composition of the complex was detected as Ga (Ⅱ): Rt = 1 : 2. The rate constant of the surface electrochemical reaction was determined as ks=4. 0×10-2s-1.
