Application
- Facile synthesis of heterojunction of MXenes/TiO2 nanoparticles: This research involves the use of potassium dichromate solution in the synthesis of advanced nanomaterials for environmental remediation, particularly for the removal of hexavalent chromium from water, underscoring its significance in environmental science and nanotechnology (Wang H et al., 2020).
Analysis Note
Concentration after dilution to 1 liter: c(K₂Cr₂O₇) = 1/60 mol/l
Amount-of-substance concentration: 1/60 mol/l
The concentration of this solution was determined with sodium thiosulfate standard solution (article number 1.09147) standardized against volumetric standard potassium iodate (article number 1.02404). The determined titer at 20°C was 1.000 with an expanded measurement uncertainty of ± 0.004 (k=2 coverage factor for 95% coverage probability). The certified value is traceable to primary standard NIST SRM 136f (NIST: National Institute of Standards and Technology, USA) by means of volumetric standard potassium iodate, measured in the accredited calibration laboratory of Merck KGaA, Darmstadt, Germany in accordance to DIN EN ISO/IEC 17025.
