The percentage of components of carbonic acid in groundwater is dependent on the pH value. Soluble CO_(2),HCO~-_(3) and CO~(2-)_(3) are the predominant components in the acidic medium with pH≤pK_(1),the neutral one with pK_(1)≤pH≤pK_(2) and the alkaline one with pH≥pK_(2),respectively.
With the addition of 1%(volume percent)carbonic acid subaltern ethylene ester(VC)or 1%(mass percent)N,N-dimethyl-2-sulfur formamide third sulfonic acid sodium(DPS)in electrolyte,the battery thickness reduced above 30% in the formation process.
3D-QSAR Study of Human Carbonic Anhydrase Ⅱ Sulfonamide Inhibitors
Methods To use Ce3+ or Pb2+ as capture agents to detect carbonic anhydrase, Na+ - K+ - ATPase, Mg2+ -ATPase, 5'-nucleotidase and NADPH oxidase activities on endosome membrane in epithelial cells of renal proximal tubules,hepatic cell of rat and human leukocytes, with cytochemical method.
Ammonium aluminum carbonate hydroxide (AACH),the precursor of alumina,has been synthesized by precipitation method using NH_4Al(SO_4)_2 and NH_4HCO_3 as raw materials under the condition of stirring speed 10000 rpm,adding dispersion 1%PEG1000 and aging 15h.
The studies over forty years on rare earth catalysts in polymer syntheses of diene, alkyne, alkylene oxide, thiirane, carbon dioxide copolymerization, lactide, caprolactone, cyclic carbonate and so forth in China have been reviewed.
Ammonium aluminum carbonate hydroxide (AACH) was prepared by a precipitation-azeotropic distillation method, which uses aluminum sulfate as the Al source and ammonium carbonate as the precipitant.
Direct synthesis of diphenyl carbonate over heterogeneous catalyst: effects of structure of substituted perovskite carrier on th
Active component Pd was loaded on various perovskite supports for synthesis of diphenyl carbonate.
Calcium carbonate crystals in scale samples were characterized by means of SEM and XRD.
An increase in the alveolar concentration of carbonic acid and a dramatic increase in the effectiveness of its elimination are significant features of the adaptive process in the mechanism of regulation of external respiration in this training.
The release of carbon dioxide to the soil air by organotrophic aerobes leads to leaching with carbonic acid and soda salinization.
It is argued that carbonates were deposited at the boundary between the "soda continent", which emerged as a result of subaerial leaching with carbonic acid, and the ocean containing Ca2+.
The mechanism of carbonic acid corrosion of ferrous metals in oxygen-free mineralized aqueous media was analyzed.
The transport of carbonic acid anions through an anion-exchange membrane (AEM) during electrodialysis is studied.
