Mehra O, Jackson M (1960) Iron oxide removal from soils and clays by a dithionate citrate system with sodium bicarbonate.
One milliliter of reagent was taken in a 12- x 75-mm glass tube, and a very small quantity (about 10 mg) of sodium dithionate powder was added.
Sodium dithionite induces sickling in vitro and adding sodium dithionate to sickled cells increases their sickling.
Ammonium oxalate extracts only poorly crystalline iron oxides while dithionate citrate extracts both poorly crystalline and well-crystallized iron oxides (such as goethite, hematite, and lepidocrocite).

First, iron oxides were removed by sodium citrate and sodium dithionate buffering techniques.
