Silica dissolution problem
Thread Content
The addition amount is 0.01–0.1% of nanoscale silica, and its content is determined using a UV spectrophotometer. Does anyone have a better method for sample dissolution?
Hello! The amount of added silica was measured; the sample is soluble in nitric acid, but the added silica does not dissolve. It becomes impossible to determine whether the amount added is the required amount.
What is silica measured in? What substance is 0.01-0.1% nano-scale silica added to? What method are you using now?

Which component or element in the sample do you want to determine? What method do you plan to use for testing? Have the current treatment methods taken into account any recommended or **standard methods? The more specific and detailed the question, the better it is for readers to understand your requirements accurately. Just shouting \"Please\" like that – are you asking for directions or begging? The people nearby don’t know. First, I’ll tell you freely an irresponsible method for dissolving silica: simply use a beaker made of polyolefin plastic and add hydrofluoric acid.
