The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: Basic copper carbonate, is researched, Molecular CH2Cu2O5, CAS is 12069-69-1, about Synergistic activation of sulfite for As(III) oxidation by basic copper(II) carbonate in homogeneous and heterogeneous processes at near-neutral conditions, the main research direction is copper carbonate arsenic catalytic oxidation density functional theory.HPLC of Formula: 12069-69-1.
Arsenic is categorized as a class I carcinogen due to its strong biol. toxicity. In this study, a novel treatment process with Cu2(OH)2CO3 as catalyst is proposed, whereby As(III) in water is oxidized by activating sulfite to generate SO4·- and SO4·- radicals. Under conditions of [Cu2(OH)2CO3]0 = 0.01 g·L-1, [sulfite]0 = 0.3 mmol·L-1, and initial pH 8.0, 94% of As(III) was converted into As(V) within 20 min, whereby dissolved oxygen had a pivotal impact on the reaction. However, HCO3-, humic acid, and fulvic acid all significantly inhibited the oxidation Heterogeneous electron transfer on the catalyst surface and homogeneous dissolved Cu2+ jointly activated sulfite in the Cu2(OH)2CO3/sulfite system, with the heterogeneous process predominating. D. functional theory (DFT) calculations disclose a dominate phys. adsorption of sulfite on Cu2(OH)2CO3 surface with 1.74 electrons transferred. >90% of As(III) was still oxidized after recycling the material five times, indicating excellent reusability. Overall, it shows good potential for application in the removal of As(III) from real water samples.
