This paper reports the anodic stripping voltammetry of trace amount of arsenic on the gold film which is deposited on a glassy graphite electrode. In 1 M sulfuric acid medium, it shows a peak of stripping current of arsenic at +0.15 V~+0.25 V (vs. 1N. Ag-AgCl). A linear relation between the peak height and the concentration of arsenic in the range of 1.0~10~(-9)M to 6.0×10~(-6)M was observed, the sensitivity of this method is about 200 times higher than that of the colorimetry of arsenic with silver diethyldithio-carbamate....

In 1 M sulfuric acid medium, it shows a peak of stripping current of arsenic at +0.15 V~+0.25 V (vs. 1N. Ag-AgCl). A linear relation between the peak height and the concentration of arsenic in the range of 1.0~10~(-9)M to 6.0×10~(-6)M was observed, the sensitivity of this method is about 200 times higher than that of the colorimetry of arsenic with silver diethyldithio-carbamate. On the other hand, we have studied the electrode process with the triangle cyclic voltammetry. It shows that the electrode reaction is irreversible and the deposition of arsenic on the gold film electrode is probably due to the formation of intermetallic compound of arsenic with gold.

本文报道了痕量砷在玻璃态石墨电极为基体的金膜电极上的阳极溶出伏安法,在1M硫酸介质中,于+0.20V左右得到一个砷的溶出峰,峰高与砷的浓度在1.0×10~(-9)M~6.0×10~(-6)M范围内有良好的线性关系。定量下限达1.0×10~(-9)M,相当于0.075ppb,比DDC银法灵敏度高出200多倍。本文并用三角波周期伏安法观察了电极反应过程,证明电极反应属不可逆反应。此外认为砷在电极上的浓集是由于形成了砷-金的金属间化合物。

Zinc plating bath containing Water Glass-DPE (III) is a new technique used in zinc plating. This bath possesses stability and may produce bright deposit. It compares favourably with cyanide zinc plating. The fundamental principles are studied qualitatively and semi-quantitatively employing techniques of single linear sweep, cyclic voltammetry and polarography. The results indicate that electrode reaction is controlled both by the rates of electron transfer and the preceding chemical reaction. The electroactive...

Zinc plating bath containing Water Glass-DPE (III) is a new technique used in zinc plating. This bath possesses stability and may produce bright deposit. It compares favourably with cyanide zinc plating. The fundamental principles are studied qualitatively and semi-quantitatively employing techniques of single linear sweep, cyclic voltammetry and polarography. The results indicate that electrode reaction is controlled both by the rates of electron transfer and the preceding chemical reaction. The electroactive species, as in the case of alkaline zincate plating, is Zn(OH)_2 Or Zn(OH)_3~-. The reason why water glass can enhance the cathodic polarization is due to the formation of mixed ligand complexes.

水玻璃锌酸盐镀锌是一种镀锌新工艺。该镀液性能稳定,镀层质量优良,可与氰化物镀液媲美。本文用动电位极化曲线法,循环伏安法以及极谱等方法对水玻璃碱性镀锌原理进行了定性和半定量的研究。实验结果表明:锌在水玻璃碱性液中电沉积的电活性粒子仍然是Zn(oH)_2、Zn(oH)_3~-,而且电沉积反应受电化学步骤和前置转化步骤共同控制。水玻璃增大镀液的阴极极化作用是由于锌能与硅结合成混合配体络合物的缘故。

The anodic stripping voltammetry of trace amounts of germanium on the gold film deposited on a glassy graphite electrode was reported. In boric acid buffer solution, at pH 10, two peaks of stripping current of germanium appear at -0.90 V and-0.17V (vs. 1N Ag-AgCl)respectively, the first peak is used for quantitative analysis. A linear relationship exists between the peak height and the concentration of germanium in the range of 1.0×10~(-8)~1.0×10~(-6)M. The detection limit is about 5.0×10~(-9)M(or 0.36 ppb)....

We have further studied the electrode process by means of triangle cyclic voltammetry and proved that the electrode reaction is irreversible and show that the first peak is due to the oxidation of metallic germanium to divalent germanium ion and the second peak due to the oxidation of divalent ions to tetravalent ions. The deposition of germanium on the gold film electrode is possibly due to the formation of an alloy of germanium and gold.
