Application Bulletin no. 43 describes the polarographic determination of copper. For copper concentrations of 10 mg/L and below, however, colorimetric methods are also used, particularly in water analysis. The method using sodium diethyldithiocarbamate can be employed down to a minimum limit of 0.01 mg/L Cu, but suffers from the drawback that the determination can also be affected by other ...

Copper (II) nitrate appears blue to the eye. This is because red light is absorbed and blue light is transmitted (Table 1). The amount of red light absorbed is directly proportional to the concentration of the copper (II) ions in the solution as defined by Beer's Law. In this experiment we will measure the absorbance of several copper (II ...

Oct 23, 2016 In an actual determination 2 grams of the ore were taken and compared with 0.5 gram of copper. The assay required 57.7 c.c. of cyanide and the standard 52.5 c.c. 52.5 : 0.5 :: 57.7 : 0.5495. This on 2 grams of ore =27.47 per cent; the same sample by electrolysis gave 27.60 per cent, of copper.
