Hello, I'm Sam.
- Background:
I'm a researcher at a nanomaterial company in Taiwan, and recently I've encountered some problems that I'd like to seek help with. The company aims to determine the release of silver ions over time from a nanosilver solution (the solution only contains nanosilver + citrate solution, where citrate is added to prevent aggregation of nanosilver, so it can be largely ignored).
- Preliminary ideas:
The plan is to centrifuge the nanosilver solution, with centrifugation conditions approximately 40,000x for 1 hour or 50,000x for 1 hour, and then take the supernatant for testing (centrifugation conditions have been tested internally in the past, which result in most of the nanosilver precipitating).
- Issues encountered:
Any thoughts or suggestions you have on the above questions would be greatly appreciated. Thank you in advance.
Gümüş iyonu miktarı suda çözünen gümüş miktarına bağlıdır. Gümüş eğer suda bulunan diğer çözeltiler ile tepkime veriyorsa ilk önce onlarla çözünen miktar hesaplanır. Daha sonra suda çözünen miktarı buna eklenir. Diğer çözücünün sudaki çözünürlüğü göz ardı edilmemeli.
Dear Mr. Aktaş,
Şükrü Aktaş Thank you very much for your advice. If I modify the solution to only consist of distilled water and nano silver (removing the citric acid component, which is feasible), do you think the potential impacts you suggest I should be cautious about might decrease to a negligible level? Thank you.
P.S. As we anticipate using this material for product manufacturing in the future, the difficulty of measurement may increase as the volume scales up. Therefore, We hope to identify a simplified and more efficient measurement method early on. Thank you.
