Nano-scale investigation of organic C sequestration and distribution on Fe oxides during ferrihydrite transformation: effect of Al-substitution
Fu Liu, Zecong Ding, Yang Lu, Rong Li, Zhenqing Shi
Abstract
Al-substitution in Fe oxides increased the sorption of aromatic C, which was dominantly bound to the outer layer of the organo–mineral interfaces as the carboxyl C was preferentially sorbed onto the surfaces of Fe oxides.
