Synthesis and properties of a newly obtained sorbent based on silica gel coated with a polyaniline film as the stationary phase for non-suppressed ion chromatography.

Highlights: [•] Silica gel with a film of polyaniline was obtained in a process in situ polymerization of aniline. [•] Uniform distribution of PANI on the surface was confirmed by Raman analysis. [•] Prepared column was tested for non-suppressed IC with spectrophotometric detection. [•] The application of silica gel modified with polyaniline for separation of selected anions with use HPIC was tested. [•] The column and optimized chromatographic system were successfully used for analysis of lake water. [ABSTRACT FROM AUTHOR]
