摘要
10十一碳烯氧肟酸(UHA)氯化锂体系中,在示坡极谱仪上,钛有灵敏的阴极波,峰电位-1.66V(vs·SCE.)。峰电流与钛浓度在1.0×10~9—1.0×10^(-7)mol L范围内呈线性关系。文中对钛UHA络合物的性质和电极过程作了讨论,确认为络合物的吸附波,电极过程不可逆。提出了钢中痕量钛的简便、准确的分析方法。
In 10 undecene hydroxamic acid lithium chloride system, with oscillopolarography, titanium produced a sensitive cathode wave. The peak potential is-1.66V(vs. SCE).Peak current of second derivative wave is propor tional to concentration of titanium in the range from (0.04—4.0)×10^(-7)mol/L. In this paper, the complex behavior and electrode process have been discussed. It is found that the polarographic wave is an adsorptive one and that the electrode process is irre versible. Furthermore, an analytical proce...
