Improved quantitative determination of benzalkonium chloride in treated wood by liquid chromatography
Abstract Ammoniacal copper quaternary (ACQ) wood preservatives contain benzalkonium chloride (BAC) as the active ingredient. BACs in commercial ACQ products comprise mainly benzyldimethyldodecyl ammonium chloride (C12 homologue) and benzyldimethyltetradecyl ammonium chloride (C14 homologue). Previou...
