Through controlling the phase transformation and chromium species under hydrothermal condition, Cr(VI) was extracted fully from hazardous Cr(VI)-containing gypsum sludge, with a very high efficiency of more than 99.5%. Scanning transmission electron microscopy, X-ray absorption fine structure, density functional theory calculation results revealed that dissolution-recrystallization CaSO4·2H2O into CaSO4 key factor to release encapsulated Cr(VI). Moreover, mineralizer (persulfate salt)...
Don't waste it! The treatment of Mg(OH)2 nanowaste containing CrVI with NaHCO3+Na2CO3 as mineralizer converts this into a nontoxic bulk material and concentrated solution the heavy metal in two-step process involving desorption rapid growth nanocrystals for complete separation from (see picture).
Hexavalent chromium contamination is a global environmental issue and usually reoccurs in alkaline reduced chromite ore processing residues (rCOPR). The oxidation of Cr(III) solids rCOPR one possible cause but as yet little studied. Herein, we investigated the Cr(OH)3, typical species rCOPR, at pH (9-11) with δ-MnO2 under oxic/anoxic conditions. Results revealed three pathways for oxic conditions: (1) by oxygen, (2) δ-MnO2, (3) catalytic Mn(II). Oxidations latter two were efficient, via...
Large amounts of wastewater containing low-concentration (<10 ppm) rare-earth ions (REIs) are discharged annually in China's mining and processing industry, resulting severe environmental pollution economic losses. Hence, achieving efficient selective recovery REIs from REIs-containing is essential for protection resource recovery. In this study, a pseudocapacitance system was designed highly capacitive using the titanium dioxide/P/C (TiO
The complexes of metal center and nitrogen ligands are the most representative systems for catalyzing hydrogenation reactions in small molecule conversion. Developing heterogeneous catalysts with similar active metal-nitrogen functional centers, nevertheless, still remains challenging. In this work, we demonstrate that coupling anti-perovskite Co4 N can be effective modulated by Cu doping to form Co3 CuN, leading strongly promoted process during electrochemical reduction nitrate (NO3- RR)...
The arsenic sulfide sludge (ASS) generated from the treatment of acidic arsenic-containing wastewater by precipitation causes severe environmental pollution due to its potential release highly toxic As(III). This work describes an alkaline-oxidative hydrothermal method that converted ASS stable johnbaumite mineral (Ca5(AsO4)3(OH)) in which exists as less As(V). Under optimal reaction conditions, i.e., with H2O2 (ω = 3.3 wt %) and Ca(OH)2 (mCH/mASS 1:1) at pH 14.18 180 °C for 18 h, leaching...
Investigations about how to recycle the deactivated nanomaterials are well-needed. This work was designed explore recycling strategy of Mg(OH)2 nanoadsorbent during treating low concentration CrVI solution as an example. It demonstrated that a reversible route between Cr-adsorbed nano-Mg(OH)2 and Cr-desorbed bulk-MgCO3·3H2O can be established by using CO2 phase transformation medium. In each adsorption−desorption cycle, with initial 10 mg·L−1 could enriched over 40 times. An...
The pH has a significant impact on arsenic (As) removal by nano zero valent iron (nZVI).
High-concentration organic nickel complexes were efficiently degraded and converted into NiFe 2 O 4 nanomaterials via Fe 3 catalytic oxidation under alkaline conditions, with high removal efficiency of (99.99%) TOC (81.94%), respectively.
The escalating frequency of thallium (Tl) contamination incidents amplifies its environmental risk. However, the potential risk Tl to aquatic organisms, especially across varying developmental stages, remains poorly understood. In this study, we employed zebrafish as a representative model organism and exposed embryos larvae at distinct periods (specifically, 6 h postfertilization (hpf) 72 hpf) low concentrations Tl(I) (0.25 0.50 mg/L). exposure was performed for short duration 24 h,...
