Waste water from electronic production factories may contain hydrophilic polymers. As a waste water model, sample containing mono- and di-valent cations in the presence of polyethylene glycol (PEG2000) was prepared. Ion chromatography (cation) column, ICYS-50 was used under non-suppressor method. All cations analyzed showed good recovery without having any effect from polyethylene glycol. Some PEG2000 is adsorbed on the column, however this can be removed by adding 50 % acetonitrile in the eluent.
Sample: 10 µL
Cation mixture in 5 % PEG2000 solution
