| Abstract: |
| The water content in fumed silica was determined by Coulometric Karl Fischer titrimetry and gravimetric method respectively and these two determinations were compared.The results showed that both could do for determinating the water content in fumed silica , but the former was
more suitable for determinating the micro content of water in fumed silica because of its higher accuracy. |
