Sažetak
It is well known that multicomponent mixtures of cationic surfactants used as biocides and/or disinfectants can act significantly more effectively against a broad spectrum of microbial organisms such as bacteria, fungi, viruses, and algae, than any of them individually. For example, Bardac™ 205M and Bardac™ 208M, both by Lonza, are made of four QAC in formulations optimized for effective action against a broad spectrum of microbial organisms in products such as hard surface disinfectants, sanitizers and/or certain types of water treatment formulations. [1] In the investigations presented here we analysed model multicomponent mixtures using highly sensitive home-made PVC based liquid membrane surfactant selective potentiometric sensors. [2, 3] Model solutions (Fig. 1) were made of quaternary ammonium compounds (QACs) used as disinfectants with a wide spectrum of action: didecyldimethylammonium chloride, dioctyldimethylammonium chloride, and polycation polyhexamethylene biguanid. All of them have confirmed disinfection and biocidal activity against SARS-CoV-2. [4, 5]
