Hematite reaction with acid

WebVandaag · Hematite (CAS: 1309-37-1) with particle size less than 100 nm was purchased from Sigma-Aldrich and was used without further purification. A hematite suspension was synthesized in a 250 mL glass beaker, which was prepared by dissolving hematite solids in a piperazine-N, N′-bis(2-ethanesulfonic acid) (PIPES) buffer solution at pH 7.5.
