Is nylon membrane or PTFE membrane used for filtration of strong acid solution?

When it comes tofiltration of strong acid solutions, both nylon and PTFE membranes can be used,but PTFE (polytetrafluoroethylene) is generally the more preferred option.

PTFE membranesare highly resistant to strong acids and other aggressive chemicals, makingthem an ideal choice for filtration in harsh chemical environments. They alsohave a wide range of chemical compatibility and exhibit low extractables and lowprotein binding, which makes them useful in applications where maximum samplerecovery is important.

Nylon membranes,on the other hand, have a lower resistance to strong acids and may not besuitable for filtration in such conditions. They are generally used forfiltration of aqueous solutions, organic solvents, and other mild chemicals.

Therefore, forfiltration of strong acid solutions, PTFE membranes are a better option thannylon membranes.
