Quantifying Soil Goethite/Hematite Ratios: A New Method Based on Diffuse Reflectance Spectra

open access: yesGeophysical Research Letters, 2023
Goethite/hematite ratios in soils are widely used to reconstruct past climatic changes, but their accurate measurements have remained challenging due to the matrix effect.

Dithionite promoted microbial dechlorination of hexachlorobenzene while goethite further accelerated abiotic degradation by sulfidation in paddy soil

open access: yesEcotoxicology and Environmental Safety, 2023
It is of great scientific and practical importance to explore the mechanisms of accelerated degradation of Hexachlorobenzene (HCB) in soil. Both iron oxide and dithionite may promote the reductive dechlorination of HCB, but their effects on the microbial

Effect of Photoreduction of Semiconducting Iron Mineral—Goethite on Microbial Community in the Marine Euphotic Zone

open access: yesFrontiers in Microbiology, 2022
Marine euphotic zone is the pivotal region for interplay of light-mineral–microorganism and elements cycle, in which semiconducting minerals exist widely and iron-bearing goethite is a typical and widespread one.

Effect of cobalt isomorphic substitution on the properties of goethite and the adsorption of lead

open access: yesFrontiers in Environmental Science, 2023
Iron oxides are ubiquitous in the environment and often contain impurities because of their substitution by Al, Mn, Co, and other metals. However, few studies have focused on Co substitution and subsequent Pb(II) adsorption on its surfaces.
