“…Previous studies have shown that a natural hexagonal birnessite with low crystallinity had a very high adsorption a nity to Pb(II) (Qin et al, 2019b;Wang et al, 2012). The adsorption capacity of birnessite for Pb(II) was 1.6-3.9 times higher than that of other metals.…”

With illegal discharge of wastewater containing inorganic and organic pollutants, combined pollution is common and need urgent attention. Understanding the migration and transformation laws of pollutants in the environment has important guiding signi cance for environmental remediation. Due to the characteristics of adsorption, oxidation and catalysis, manganese minerals play important role in the environment fate of pollutants. This review summarizes the forms of interaction between manganese minerals and metals, the environmental importance of the interaction between manganese minerals and metals, and the contribution of this interaction in improving performance of Mn-based composite for environmental remediation. The literatures have indicated that the interactions between manganese minerals and metals involve in surface adsorption, lattice replacement and formation of association minerals. The synergistic or antagonistic effect resulted from the interaction in uence the puri cation of heavy metal and organism pollutant. The synergistic effect bene ted from the coordination of adsorption and oxidation, convenient electron transfer, abundant oxygen vacancies and fast migration of lattice oxygen. Based on the synergy, Mn-based composites have been widely used for environmental remediation. This review is helpful to fully understand the migration and transformation process of pollutants in the environment, expand the resource utilization of manganese minerals for environmental remediation.

“…This evidence suggests that B-species are partitioned onto surfaces of Mn-rich minerals in Group 1 waters. These solids generally have an amorphous or cryptocrystalline nature (Qin et al, 2019) and show high surface reactivity toward dissolved metal species (Stumm, 1992). Since surfaces of Mn-rich minerals are negatively charged under ionic strengths higher than 0.1 M (Tsadilas et al, 1998;Villalobos, 2015;Kosmulski, 2016;Brodskii et al, 2015) and the proportion of positively charged borate ion-complexes is likely more abundant, the observed fractionation of B/Li ratio in Group 1 waters could result from the adsorption of charged B species onto surfaces of Mn-rich minerals.…”
