<p indent=0mm>Hydrolysis and precipitation are the key processes that determine coagulation performance of inorganic metal salts. The valence concentration salts, ligands, solution pH all influence performance. In order to get a full picture on pros cons various salts as coagulants, this paper conducted thermodynamic equilibrium calculations experiments analyze verify hydrolysis-precipitation areas speciation four (aluminum, iron, titanium, zirconium) in absence presence ligands. addition,...
The coexistence of selenite (Se(IV)) and acetylacetone (AA) generated a synergistic effect on the growth inhibition bloom-forming cyanobacterium, Microcystis aeruginosa. mechanism behind this phenomenon is great significance in control harmful algal blooms. To elucidate role Se(IV) effect, reactions ternary solutions composed Se(IV), AA (or two other similar hydrogen donors), quinones, especially benzoquinone (BQ), were investigated. transformation kinetic results demonstrate that played...
Tellurium (Te) is a rare element of great value, but it exists mainly in the toxic form tellurite (TeIV) water. Effective approaches that are able to reduce toxicity and recover Te from contaminated water highly needed. Here, we developed simple effective way TeIV widely applicable elemental Te0. With combination ultraviolet (UV) biacetyl (BD), oxidation state could be feasibly changed IV 0 or VI. The consumption dissolved oxygen (DO) was key factor redox conversion TeIV. Under UV...
Redox transformation is a useful strategy to reduce the toxicity of metal oxysalts and facilitate their removal from water. The synergy oxidation reduction processes in single system great value for treatment wastewater containing multiple pollutants. Here, by taking As(III) Cr(VI) as modeling pollutants, synergic effect redox coexisting oxyanions was evaluated with typical advanced process (AOP)─UV/H2O2, well-established (ARP)─UV/sulfite, newly developed UV/acetylacetone (AcAc) process. At...
Organophosphonates are a group of chemicals that difficult to be directly removed through coagulation and recalcitrant conventional Fenton oxidation (pH 3.0). The excessive discharge these into the environment can lead severe consequences. In this study, we successfully addressed challenge by introducing combined approach followed coagulation. For first time, was found effective for degradation representative phosphonate, amino trimethylene phosphonic acid, at circumneutral pH 8.0. This...
Controllable synthesis, proper dispersion, and feasible functionalization are crucial requirements for the application of nanomaterials in many scenarios. Here, we report an all-in-one approach synthesis gold nanoparticles (AuNPs) with simplestβ-diketone, acetylacetone (AcAc). With this approach, particle size resultant AuNPs was tunable by simply adjusting light intensity or AcAc dosage. Moreover, owing to capping role AcAc, could be stably dispersed water a year without obvious change...
Typical metal–organic frameworks (MOFs) usually suffer from a limited visible light-trapping ability and easy recombination of charge carriers, hindering their photocatalytic applications. Acetylacetone (AA), leveraging its exceptional coordination capabilities, serves as versatile effective modifier for enhancing the activity MOFs via post-synthesis approach. The synthesis diketone-anchored with AA can be achieved by first diazotizing amino groups on ligands MOFs, followed condensation...
This study seeks to elucidate the fundamental principles underlying hydration, hydrolysis, and enolization of β-diketones, aiming enhance students' comprehension link between chemical practical implications keto–enol tautomerization diketone-gem diol equilibrium in diverse reactions. The research explores hydration hydrolysis kinetics β-diketones using NMR UV spectroscopy as well substituent effects on these their influence enolization. insights gained from this are valuable for students...
Machine learning (ML) is becoming an efficient tool for predicting the fate of aquatic contaminants owing to preponderance big data. However, whether ML can “learn” differences in reactivity among different free radicals has not yet been tested. In this work, effectiveness combining algorithms with molecular fingerprints predict three evaluated. Firstly, a dataset containing 211 and their rate constants carbonate radical (CO3•−) was used develop predictive models by linear regression ML. The...
Organoarsenics pose a severe threat to the environment and human health. In aquatic environment, dissolved organic matter (DOM)-mediated photochemical transformation is one of main processes in fate variant pollutants, including organoarsenics. Dicarbonyl typical redox-active moiety DOM. However, knowledge on photoconversion organoarsenics by DOM, especially contributions dicarbonyl moieties still limited. Here, we systematically investigated three with simplest β-diketone, acetylacetone...
