Electrochemical Perspective on Hematite–Malonate Interactions

open access: yesColloids and Interfaces, 2021
Organic matter (OM) interactions with minerals are essential in OM preservation against decomposition in the environment. Here, by combining potentiometric and electrophoretic measurements, we probed the mode of coordination and the role of pH-dependent ...
