有机染料及其与稀土络合物的极谱行为报导不多。本文找出了某些有机染料及其在稀土存在下的极谱波,并着重研究了紫脲酸铵及其与稀土络合物的极谱性能,测定了其稳定常数。实验部分极谱仪为V301型,附检流计最大灵敏度为4.4×10~(-9)安培/毫米/米。电解池为Kalousek式,饱和甘汞电极为参比电极。滴汞电极在0.1M氯化钾溶液中在汞柱高度为64厘米时,汞流量为0.82毫克/秒。自由滴下时间为4.1秒。实验温度保持25±0.2℃。用高纯氮气除氧。
The polarographic behavior of organic dyes and their complexes with rare earths has not been reported. In this paper, some organic dyes and their polarographic waves in the presence of rare earths were identified. The polarographic properties of ammonium urethane and its complexes with rare earths were also investigated. The stability constants were also determined. Experimental part of the polarographic instrument for the V301 type, with the maximum sensitivity of the flow meter 4.4 × 10 ~ (-9) Ampere / mm / m. Electrolyser for the Kalousek-type, saturated calomel electrode as a reference electrode. The mercury droplet was 0.82 mg / sec at a mercury column height of 64 cm in 0.1 M potassium chloride solution. Free dripping time of 4.1 seconds. The experimental temperature is maintained at 25 ± 0.2 ° C. With high purity nitrogen oxygen.
