The adsorption characteristics of the nickel complex with dimethylglyoxime (DMG)Ni (Ⅱ)A_2 at the HMDE has been investigated It was found that between-0.20 and-0.90V (vs. SCE) Ni (Ⅱ)A_2 can be adsorbed fairly well at the HMDE and the rela-tionship observed by voltammetry with linearly changing tension between the logari-thm of the peak current and the logarithm of the sweep velocity is linear and has a slopeof 0.98. Experimental peak currents show a Langmuir isotherm with the preconcentrationtime. The overall reaction of the adsorption voltammetry of nickel-DMG system, whichcan be divided into three parts, has been discussed. That is 1) Homogeneous reactionbetween different nickel species in solution, 2) Adsorption preconcentration process ofNi(Ⅱ)A_2, 3) Reduction of adsorbed Ni(Ⅱ)A_2, by irreversible charge transfer. Thesensitivity of the method appears between 10~(-9)M and 10~(-10)M depending on the precon-centration time.

The behaviour of the cobalt complex with dimethylglyoxime(DMG), Co(Ⅱ)A_2, at the mercury electrode has been investigated in details. The adsorption phenomena have been observed by both normal pulse polarography and voltammetry with linearly changing tension. Experimental superficial concentrations show a Langmuir isotherm with both the concentration of Co(Ⅱ)A_2 and the preconcentration time. The superficial concentration equation for adsorption voltammetry, corresponding to the condition of the lower coverage of the electrode surface, is deduced as follows

本文对钴(Ⅱ)与丁二肟配合物Co(Ⅱ)A_2在悬汞电极上的吸附伏安法作了研究。在-0.60~-0.90V(vs.SCE)Co(Ⅱ)A_2能在悬汞电极上很好地吸附,当电极向阴极方向扫描时,吸附在电极上的Co(Ⅱ)A_2分二步不可逆地还原到Co(O)(Hg)。本文导出了在低覆盖度下富集阶段电极表面吸附量的表达式,实验结果与理论推导相符。理论上分析了不可逆过程线性扫描吸附伏安法的灵敏度。影响灵敏度的主要因素是吸附富集时间,当富集120秒时,检测下限可达1×10~(-9)M,此结论得到实验证实。

In the medium of HAc-NaAc, Th~(4+) canbe combined with HTTA to form a comparatively steady ternary chelate whichwill be adsorbed and preconcentrated on the mercury electrode and determined bycathodic stripping voltammetry. At a controlled potential of -0.1 V (vs.SCE), thechelate is adsorbed and preconcentrated for 3 min., then by cathodic scanningtill -1.0v(vs. SCE), a highly sensitive peak...

A study on the complexing-adsorption voltammetry for direct determinationof trace Th(Ⅳ) in water is described. In the medium of HAc-NaAc, Th~(4+) canbe combined with HTTA to form a comparatively steady ternary chelate whichwill be adsorbed and preconcentrated on the mercury electrode and determined bycathodic stripping voltammetry. At a controlled potential of -0.1 V (vs.SCE), thechelate is adsorbed and preconcentrated for 3 min., then by cathodic scanningtill -1.0v(vs. SCE), a highly sensitive peak of reduction current will be shownat about -0.60V(vs. SCE). The height of peak is linearly related to the concen-tration of Th~(4+) in the range of 2.0×10~(-9)mol/l to 1. 0×10~(-7)mol/l, the detectionlimit will be 1. 0×10~(-9)mol/l, the relative standard deviation for seven paralleldetermination is shown to be 2.51%. The mechanism of adsorption stripping andthe conditions for determination have been discussed. The method has been usedto determine the trace Th~(4+) in the industrial waste water with satisfaction.

本文对吸附伏安法直接测定水体中痕量钍作了研究。在HAc-NaAc介质中钍离子(Th~(4+))和噻吩甲酰三氟丙酮(HTTA)形成较稳定的三元络合物,先吸附富集在悬汞电极上,后采用阴极溶出伏安法检测痕量钍。控制电位为-0.1伏(VS.SCE)吸附富集3分钟,然后阴极扫描至-1.0伏(VS.SCE),在-0.60伏(VS.SCE)电位处获得一个高灵敏度的还原电流峰。钍离子浓度在2.0×10~(-9)mol·1~(-1)~1.0×10~(-7)mol·1~(-1)范围内,溶出峰高和钍离子浓度呈良好的线性关系,最低检测限达1.0×10~(-9)mol·1~(-1),在含5.0×10~(-8)mol·l~(-1)钍离子的体系中,连续测定七次相对标准偏差为2.51%。同时我们还对该体系的吸附溶出机理和测定条件作了探讨,并利用该法对工业排放废水中的痕量钍进行了测定,其结果良好。
