Oxalic Acid This is a potent metabolic poison that combines with calcium to limit its bioavailability, thereby limiting muscle contraction.48 It is used industrially to remove rust and in bleaching products. Treatment consists of water irrigation and IV calcium, with continuous cardiopulmonary monitoring...
A. niger, in contact with a poor nitrogen medium, can have the metabolic pathway altered and begin to produce oxalic acid; when there is nitrogen in excess, an increase of microorganism growth occurs, and both situations are negative for CA synthesis [48]. Some metal ions can favor CA ...
Photocatalytic hydrogen evolution using oxalic acid as electron donor has been investigated over Pt–TiO 2 prepared by photodeposition. The reaction kinetics is consistent with the Langmuir model. The effects of pH, amount of deposited Pt and additives of inorganic anions on the rate of the reaction...
The application of phytic acid in metal protection was researched by weight-loss method.Using 0.1 mol/L HCl,0.1 mol/L NaCl or 0.1 mol/L NaOH respectively as the medium,different concentrations of phytic acid(blank water,0.5%,1%,1.5%,2%) were prepared,compared with the solution of 1.5% NaN...
We confirmed that chlorhexidine decontamination yielded more nontuberculous mycobacteria than did the N -acetyl- l -cysteine-NaOH-oxalic acid procedure fro... Annelies De Bel,Deborah De Geyter,Iris De Schutter,... - Journal of Clinical Microbiology 被引量: 0发表: 2013年 Effect of Oxalic Acid o...
Experts are tested by Chegg as specialists in their subject area. NO2 dissolves very well in water react with water to give nitrous acid and nitric acid. It is used to destroy the potentially explosive sodium azide. Just because a teacher is good at chemistry, this is no indication of thei...
(treatment of oxalic acid with NaOH in a 1:2 acid-to-base molar ratio) yields NaOOCCOONa,sodium oxalate. If desired, the half-neutralization can be done with one base and the rest with another, to produce a mixed salt, as, for example, KOOCCOONa—sodium potassium oxalate. All ...
Both inorganic (H2SO4, HNO3, H3PO4, HCl, H2SO3) and organic acids (oxalic acid, malic acid, acetic acid) were reported for their application in pretreating lignocellulose biomass feedstocks. The yields and efficiencies of dilute organic acid pretreatment of corncob were reported as: HCl (Hydro...
