Ethylacetoacetate-Cadmium 錯體의 Polarograph的 硏究
黃在順,黃三榮 全北大學校 1984 論文集 Vol.26 No.-
Polarographic behavior of Cadmium-Ethylacetoacetate Chelate in the methyl alcohol and 0.3M NaClO_4 supporting electrolyte was studied in detail. The electrode reaction was found to be a reversible polarographic wave corresponding to two electron reduction and diffusion controlled, and reduction half wave potential was -0.59V(vs. SCE) in this case, assuming that metal complex Cd(EAA)_2 is reduced reversibly with two electron transfer, the electrode reaction is given as follows Cd^+2(EAA)n+2e ↔Cd+nEAA
Salicylaldehyde-Acetonitrile 非水溶媒中에서 亞鉛의 直流 Polarograph定量法
黃在順,黃三榮 全北大學校 基礎科學硏究所 1985 基礎科學 Vol.8 No.1
A method for the direct current polarographic determination of metallic zinc dissolved directly in organic solvent, salicylaldehyde, as metal-solubility in salicylaldehyde acetonitrile and 0.2M LiClO_4 supporting electrolyte, was studied. The solution of zinc was taken into a cell. After dried nitrogen gas was passed through it for 20 min. the direct current polarogram in the region of applied potential from 0.0-1.0V(vs. SCE) was recorded and all experiments was carried out at 25.0 ± 0.5℃. A reversible polarographic reduction wave was obtained and the reduction half wave potential was-0.56V(vs, SCE). Zinc was determined by refering to the calibraton curve.
