Application: | Nitric acid (HNO3) may be used for the removal of transition metal catalyst from the single-walled carbon nanotubes (SWNTs) during the purification of SWNTs. It may be used in the trace determinations of Pb and Cd in natural waters by flame atomic absorption spectrometry. |
General description: | A yellow coloration of the bottle has no influence whatsoever on the product quality. |
General description: | Nitric acid (HNO3) is a highly corrosive strong mineral acid. 10%(v/v) nitric acid solution is useful for cleaning laboratory glasswares. Reaction of HNO3 with various original and synthetic mineral dust/mineral oxide surfaces was studied in a low-pressure Knudsen reactor operating at 298K. |
Other Notes: | The article number 30709-4X2.5L will be discontinued. Please order the single bottle 30709-2.5L which is physically identical with the same exact specifications. |
