Adsorption of benzalkonium chloride by filter membranes: mechanisms and effect of formulation and processing parameters.

Abstract

The purpose of this study was to elucidate the mechanism(s) of adsorption of benzalkonium chloride (BAK) by filter membranes and to determine the effect of formulation and processing parameters on the adsorption of BAK. Six different sterilizing grade filter membranes were used in this study. Adsorption was monitored by passing an aqueous solution of BAK at… (More)
