A comparison between two treatments for the removal of iron oxides from thin sections of a soil.

Abstract

Dithionite-citrate-bicarbonate appeared more efficient on concretions, while iron of nodules was removed more efficiently by the oxalate treatment. The combination of optical and chemical methods seems to be a very promising approach in this kind of experiment. -from Authors dithionite citrate bicarbonate oxalate treatment optical chemical methods iron oxide removal
