Abstract
We made use of the apparatus described in the preceding paper to study the electrochemical behavior of adrenalin.If adrenalin in aqueous solution is added to the middle division of our apparatus, a current of 1 Milliamp. and 4 volts will effect a migration of this substance in the direction of the electrodes. It will be noted that adrenalin passes through the Norton Alundum discs used as diaphragms as well as through various Zsigmondy filters. All qualitative determinations of adrenalin were made by means of iron chloride, gold chloride and Folin's reagent. Quantitative experiments showed that the migration of adrenalin in the direction of both poles occurs unequally. After the addition of alkali or alkaline salts to a solution of adrenalin hydrochloride a greater amount of adrenalin migrates in the direction towards the positive pole, while the addition of acid or acid salts causes a more marked migration in the opposite direction. The quantitative determination was carried out by the method of Folin as ...
