Wet oxidation of organic matter employing perchloric acid at graded oxidation potentials and controlled temperatures

A new modified apparatus has been described for use in the wet ashing of organic matter using boiling, controlled concentrations of perchlouc acid as oxidant Typical operative procedures and manipulations are discussed and a number of direct applications. to various types of materials has been demonstrated Cellulose, proteins, and sugars and materials predominating in these types, have been selected as best applicable examples Perchloric acid concntrations tested were from 55-–68 percent and intermediate concentrations The procedures described provide conditions which though effective are less encumbered by the implication of ha/ard often charged against 70–72 5 per cent perchloirc and in similar previously published and widely applied procedures.
