Determination of free silica in dust particles: effect of particle size for the X-ray diffraction and phosphoric acid methods.
The X-ray diffraction method and the phosphoric acid method are widely used to determine the fraction of free silica (mainly quartz and other silica polymorphs) in respirable dust sampled in working environments in Japan. In this study, we clarified the size effect of quartz dust for the X-ray diffraction method and the phosphoric acid method using size controlled quartz samples. The quartz sam...
متن کاملA Method for the Determination of Adenosine- 5’-phosphoric Acid and Its Homologues*
For the determination of adenosine-5’-phosphoric acid and its homologues the methods which have been recommended chiefly are (1) enzymatic deamination by deaminase and quantitative determination of the ammonia split off (1) ; (2) determination on the basis of the pharmacological activity, (a) contraction of the isolated guinea pig uterus, (b) the characteristic change in the electrocardiogram u...
متن کاملDetermination of L- Ascorbic Acid in Plasma by Voltammetric Method
Voltammetric techniques have been considered as important methods among the analytical techniques used for the identification and determination of trace concentrations of many biological molecules such as L-ascorbic acid (AA). L-ascorbic acid is an electro-active molecule, though it is difficult to determine its value directly with a majority of electrodes made of carbon and transition metals, ...

متن کاملOxygen Reduction on Gas-Diffusion Electrodes for Phosphoric Acid Fuel Cells by a Potential Decay Method
The reduction of gaseous oxygen on carbon-supported plat inum electrodes has been studied at 150~ with polarization and potential decay measurements. The electrolyte was either 100 weight percent phosphoric acid or that acid with a fluorinated additive, potassium perfluorohexanesulfonate (C6FI3SO3K). The pseudo-Tafel curves of the overpotential vs. log (iiL/(iL -i)) show a two-slope behavior, p...
