Formation, properties and reactivity of coprecipitates and organomineral complexes in soil environments

Abstract: In soil environments the formation of simple coprecipitates formed by the interaction of two or more cations and/or anions are the rule and not the exception. In this review we describe the formation, the nature and the reactivity of coprecipitates formed by the interaction between cations (Fe, Al, Mg, Mn, Zn) with the formation of mixed oxides or layered double hydroxides (LDHs) and of coprecipitates formed by the interactions of inorganic and low molecular mass organic (LMMOLs) ligands with OH-Al and/or OH-F… Show more

“…Recently, a class of anionic clays known as layered double hydroxides (LDHs) was found to be particularly effective in the removal of inorganic As from contaminated solutions [16,17]. LDHs are easy-to-synthesize minerals, very similar to the green rusts naturally occurring in hydromorphic soils under reducing conditions, due to the slow oxidation of Fe [18,19]. In this type of soil, widely exploited for agricultural purposes to produce rice (a staple food worldwide), where the reducing conditions of aquifers promote the dissolution of large amounts of As in the groundwater [3], the presence of effective adsorbents such as LDH-based green rusts may strongly mitigate the mobility of inorganic As at the soil-water interface.…”

“…Os FOM são misturas físicas ou combinadas de material orgânico e fertilizante mineral (BRASIL, 2020). Além de fornecerem K, também possuem outros nutrientes importantes para as plantas, como N e P, e contribuem para a melhoria das propriedades físicas, químicas e biológicas do solo Moran et al, 2021).…”
