Cellulose acetate filters dissolve completely in acid solutions, so if you have a good quality with sufficient porosity - say 0.45 µm - and strength, then total dissolution can be achieved for a range of for instance metals in aerosols, followed by ICP-MS analysis. Check here for more information:

good luck with your work!

Cellulose acetate can contain metals like iron. In any case, when using a filter that is not familiar, you need to test for leaching of metals from the material by filtering a blank in the matrix your samples will be in. Also, always filter a standard of , again in the sample matrix, to be sure that you do not lose the analyte(s) of interest.

Those two steps upfront can save lots of rework later!

Lynn Egan is right, of course. Blanks should always be included in the analysis. In the article mentioned in my reaction this step is included too.

Maybe you should consider for swelling degree because the CA is organic polymers that absorb the water. So I think it will affect to the %recovery

Thank you very much for all answers. Those are really helpful for me and for my study. Ayan Das
