Low molecular weight organic acids stabilise siderite against oxidation and influence the composition of iron (oxyhydr)oxide oxidation products Siderite (FeCO3) is an important reservoir of mineral-bound ferrous iron in non-sulfidic, reducing soils and sediments. It is redox sensitive, and its oxidation may facilitate the reduction of a range...

It’s been a while since I was active here, but I’m back yay with a plug for a new paper: pubs.rsc.org/en/content/a... When I first worked on this I didn’t understand why my very air sensitive siderite wasn’t oxidising in some tests, we show that it was being stabilised by organic acids.

Excited to share that I've been awarded a SNSF Starting Grant for my project ''Mineral-Mediated Organic Carbon dynamics in soils and sediments (MIMOC)''! 🎉We'll study mineral-carbon dynamics in the lab and the field using stable isotopes. Huge thanks to @snsf-ch.bsky.social 🙌!
