Iron Oxide Removal from Soils and Clays by a Dithionite-Citrate System Buffered with Sodium Bicarbonate
TL;DR: In this article, the bicarbonate-buffered Na2S2O4-citrate system was used for removing free iron oxides from latosolic soils, and the least destructive of iron silicate clays.

Source type ascription for fluvial suspended sediment based on a quantitative composite fingerprinting technique
TL;DR: In this article, the authors report the successful application of a quantitative composite fingerprinting technique, incorporating both a rigorous statistical verification procedure for composite signatures and a multivariate mixing model, to evaluate sediment source type in the Dart catchment, Devon, UK and the Plynlimon experimental catchments, Powys, UK.

Procedure for Special Type of Mechanical and Mineralogical Soil Analysis
TL;DR: In this paper, it was found that the addition of oxalic acid to a soil suspension containing sodium sulfide, producing nascent hydrogen sulfide is many times more effective than ordinary hydrogen sulfides for this purpose, and it was possible to dissolve the free iron oxide in about ten minutes without greater acidification than pH 3.5.
