Metakaolin/red mud-derived geopolymer monoliths: Novel bulk-type sorbents for lead removal from wastewaters

Joao Carvalheiras et al.

Summary: The study synthesized geopolymer monoliths using metakaolin and red mud as solid precursors, which have hierarchical porosity and suitable compressive strength, making them effective bulk-type sorbents for heavy metal removal. The use of red mud-containing geopolymer monoliths in extracting lead from wastewater was evaluated, and the results showed high lead removal capacity and successful regeneration for multiple sorption cycles. These findings contribute to the potential industrial application of clay derived geopolymers in wastewater treatment and provide a sustainable recycling strategy for red mud waste.

Characterization of arsenite (As(III)) and arsenate (As(V)) sorption on synthetic siderite spherules under anoxic conditions: Different sorption behaviors with crystal size and arsenic species

Seon Yong Lee et al.

Summary: The uptake of Arsenite (As(III)) and arsenate (As(V)) by synthesized small- and large-sized siderites (S-siderite and L-siderite) and the effects of crystal size on arsenic sorption were investigated. The results showed that the sorption affinity of S-siderite depends more on the arsenic species (III and V), and the sorption behaviors and mechanisms are strongly dependent on the arsenic species and the crystal size of siderite.

Facile preparation of novel magnetic mesoporous FeMn binary oxides from Mn encapsulated carboxymethyl cellulose-Fe(III) hydrogel for antimony removal from water

Qiao Li et al.

Summary: In this study, magnetic mesoporous FeMn binary oxides (MMFMs) were fabricated and showed excellent mass transfer and adsorption ability to remove Sb(III) and Sb(V). The structure of MMFMs was closely related to the Fe:Mn ratio and the FeOx content played a major role for the adsorption of Sb(V). The generated inner-sphere FeOSb complex dominantly contributed to the removal of Sb(III/V).

Magnetic sporopollenin supported polyaniline developed for removal of lead ions from wastewater: Kinetic, isotherm and thermodynamic studies

Nazanin Mosleh et al.

Summary: This study synthesized a novel binary functional adsorbent, MSP-PANI, based on sporopollenin, magnetic nanoparticles, and polyaniline, and applied it to enhance the uptake of lead ions from wastewater. The nanocomposite's functionalities, surface morphology, magnetic properties, and elemental composition were investigated. The adsorption process showed that MSP/PANI ratio of 1:1, pH 6, adsorbent dosage of 40 mg, and contact time of 90 min at room temperature were optimal. The maximum adsorption capacity for lead ions was 163 mg/g, and the adsorption mechanism was identified as physio-sorption with endothermic nature.

Release and fate of As mobilized via bio-oxidation of arsenopyrite in acid mine drainage: Importance of As/Fe/S speciation and As (III) immobilization

Hong-Rui Chen et al.

Summary: Mining activities expose sulfidic minerals to acid mine drainage, resulting in the release of toxic arsenic. This study investigated the transformation of secondary products and arsenic speciation during arsenopyrite bio-oxidation, as well as the immobilization of solubilized arsenic using red mud.

Graphene oxide supported sulfidated nano zero-valent iron (S-nZVI@GO) for antimony removal: The role of active oxygen species and reaction mechanism

Zifang Chi et al.

Summary: By using graphene oxide (GO) as a carrier, graphene oxide supported sulfidated nano zero-valent iron (S-nZVI@GO) was successfully synthesized. S-nZVI@GO exhibited excellent performance in the removal of antimony (Sb), with high adsorption capacity and a high removal rate over a wide pH range. Moreover, S-nZVI@GO activated molecular oxygen in water to produce organic peroxides and hydroxide, oxidizing trivalent antimony (Sb(III)) to pentavalent antimony (Sb(V)) for further separation.

Schwertmannite transformation to goethite and the related mobility of trace metals in acid mine drainage

Heon-Jung Kim et al.

Summary: The study found that most trace metals decreased their mobility during the transformation of schwertmannite to goethite, with the exception of lead which increased its mobility. Lead, arsenate, and chromate were well retained in schwertmannite, while elements like cadmium and cobalt had higher exchangeable fractions and were easily released into water.

New insights on nanostructure of ordered mesoporous Fe-Mn bimetal oxides (OMFMs) by a novel inverse micelle method and their superior arsenic sequestration performance: Effect of calcination temperature and role of Fe/Mn oxides

Jun Lu et al.

Summary: A series of ordered mesoporous Fe-Mn bimetal oxides were fabricated and exhibited superior arsenic sequestration performance, with the optimum Fe/Mn ratio of 3/1 and calcination temperature of 350 degrees C. The maximum As(III) and As(V) adsorption capacities were 174.59 and 134.58 mg/g, respectively. The bimetal oxides showed promising potential for arsenic-contaminated surface water and groundwater remediation.
