Polarographicdata are presented for the reduction of selenite ion in 3M sulfuric acid, 1M potassium chloride, and 1M ammonia-ammonium chloride. In these first two media two waves are obtained correspondingto the diffusion-controlled reduction of selenite ion to selenium amalgam and the adsorption of selenite ion on the mercury drop, respectively. One wave is obtained in ammonia-ammonium chlorid...

The bilirubin-albumin solution containing 16 ing/100 ml of bilirubin and 2.5 g/100 ml of albumin was made according to Shinowara (i). The blank solution without bilirubin contained the same amount of albumin as the test solution. The Brdicka ilonfiltrate reaction was carried out as follows (2): 0.1 nil of test/blailk solution was added to 1.4 ml of 0.9% (w/v) NaC1 solution, and 1.5 ml of 0.25 N...

Polarographic studies of potassium isobutyl xanthate at a mercury electrode reveal that the product of an anodic reaction is strongly adsorbed at the mercury surface, as indicated by a prewave. The adsorbed film greatly affects the characteristics of the anodic wave of xanthate in an aqeous medium. The current of total wave is proportional to the concentration of xanthate from 0.32 to 1.6 mM.
