求助重量法测SiO2含量的翻译
|
||
| Silica contents of calcined rice husks and rice husk ashes were determined with gravimetric method. The weighed sample was thoroughly moistened in the platinum crucibles with distilled water. Four drops 1+1 H2SO4, followed by 10 ml HF were added. The mixture was slowly evaporated to dryness over a hot plate in a hood. The crucible was ignited to constant weight at 1200℃ and the weight of the crucible and contents were recorded. The weight of crucible and contents after the HF treatment subtracted from the corresponding weight before HF treatment. Silica was determined as loss on volatilization. |
