The formic acid catalyzed gas-phase reaction between H(2)O and SO(3) its reverse are respectively investigated by means of quantum chemical calculations at the CCSD(T)//B3LYP/cc-pv(T+d)z CCSD(T)//MP2/aug-cc-pv(T+d)z levels theory. Remarkably, activation energy relative to reactants for with is lowered through catalysis from 15.97 kcal mol(-1) -15.12 -14.83 formed H(2)O⋅⋅⋅SO(3) complex plus HCOOH H(2)O⋅⋅⋅HCOOH SO(3), respectively, level. For reaction, barrier decomposition sulfuric reduced...
The degradation of typical dye wastewater is a focus research in the printing and dyeing industry. In this study, combined micro-electrolysis microbial treatment method was established to treat refractory wastewater, pivotal factors were optimized. series coupled modes, removal rates chroma reached 98.75% 92.50%, chemical oxygen demand (COD) 96.17% 82.29%, respectively. high-throughput sequencing results showed that communities system varied at different stages. From culture stage...
Biomimetic approach is a nature‐driven strategy for designing functional materials to meet the industrial challenges. Here we demonstrate bio‐inspired discovery of self‐activating catalyst, with polydimethylsiloxane anchored over surface CrOx/Al2O3, exhibiting comparable performance noble metallic catalysts acetylene semi‐hydrogenation. In addition, dynamic movement polymer chains high flexibility renders catalyst impose proactive perturbation undesired coke precursors generated in reaction,...
Abstract Seasonal changes over 2 years (2004–2006) in soil moisture content (θ v ) of frozen alpine frost meadow soils the Qinghai‐Tibet plateau permafrost region under three different levels vegetation cover were investigated. Vegetation and air temperature had significant effects (synergistic effect) on θ its distribution profile. During periods freezing or thawing, less cover, quicker drop rise water, shorter duration water freeze–thaw response active layer. Under 30% 65% amplitude...
The reactions of H2SO4 with the OH radical without water and are investigated employing quantum chemical calculations at B3LYP/6-311+G(2df,2p) MP2/aug-cc-pv(T+d)z levels theory, respectively. calculated results show that reaction H2O is a very complex mechanism because formation prereactive prior to transition state product. There two complexes stabilization energies being −20.28 −20.67 kcal/mol, In addition, single can lower energy barriers hydrogen abstraction proton transfer 7.51 6.37...
Abstract From 1998 to the present, Chinese government has implemented numerous large-scale ecological programs restore ecosystems and improve environmental protection in agro-pastoral ecotone of Northern China (APENC). However, it remains unclear how vegetation restoration modulates intraregional moisture cycles changes regional water balance. To fill this gap, we first investigated variation precipitation (P) from Meteorological Forcing Dataset evapotranspiration (ET) estimated using...
Abstract Technologies for domestic sewage treatment with low excess sludge yield rate and highly efficient biological methods are needed, the moving-bed biofilm reactor has great promise meeting this need. To provide technical support of typical sewage, paper provides an estimate bacterial diversity in polyvinyl alcohol (PVA) gel beads determined by a 16S-rRNA gene-based polymerase chain reaction-denaturing gradient electrophoresis (PCR-DGGE) approach, proposes method reducing rate,...
Abstract In this study, the removal of salicylic acid (SA) in water by ozone (O3) and ultraviolet/ozone (UV/O3) processes was investigated. Results showed that more than 50% SA (10 mg/L) could be effectively removed after 1 min during these two processes. However, UV/O3 process much effective O3 for mineralization, total organic carbon reduction 30 69.5% 28.1%, respectively. processes, optimum pH value 4.3, while mineralization 10.0. Both bicarbonate dissolved significantly inhibited Eleven...
Treatment of dye wastewater with a chemical oxygen demand (COD) 1000–1600 mg/L was studied by the use continuous iron-carbon microelectrolysis process (MEP) and microelectrolysis–upflow anaerobic sludge blanket (UASB)–sequential batch reactor (SBR) (MEUSP). Results indicated, first, that high-temperature processing to generate microporous MEM can effectively prevent caking MEM. MEP displayed good performance in treatment wastewater, color removal 75% COD more than 60% when hydraulic...
Rivers are the critical link between soil, atmosphere, and ocean’s extensive carbon reservoirs, but discharge of sewage into rivers has not only increased content organic matter also significantly altered geochemical cycles nitrogen in land, water, atmosphere. However, few studies have been conducted to establish relationship changes distribution river pollutants cycle. In this study, twenty water samples were collected from sixteen middle reaches Yellow River (YR). The results showed that...
