A Simple Field Test for the Detection of Manganese in Quaternary Deposits
Published online by Cambridge University Press: 20 January 2017
Abstract
In the field it is often difficult to distinguish black manganese dioxide from specks of charcoal or other organic materials. Misinterpretations can be avoided by testing the earth material with a small amount of potassium periodate which will oxidize any manganese to the highly colored permanganate ion.
