Abstract

One of the best methods for the determination of manganese in very small amounts in biological material is the adaptation of Willard's oxidation of the Mn in acid solution by KIO₄ , and a comparison in Nessler tubes of the color produced, with a known standard similarly treated. Skinner and Peterson showed that if animal tissue was ashed in a muffle furnace and extracted with H2PO₄ , the KIO₄ oxidized the Mn in the solution without loss of color. They found 0.01 mg Mn in 50 cc. solution gave a readable color in Nessler tubes against an inverted V of white paper.
