Sažetak
In this paper the adsorption and desorption of cationic surfactants on standard cotton fabric was researched, as well its influence to fabric antimicrobial properties. Four different QACs: Hexadecyltrimethyl ammonium chloride (HDTMAC), Hexadecyltrimethyl ammonium bromide (HDTMAB), N-cetylpyridinium chloride (N-CPC) and Cetylpyridinium bromide (CPB), have been used. The adsorbed QAC amount, as well as desorbed amount, were determined indirectly by potentiometric titration using ion-selective electrode. The antimicrobial activity was determined according to AATCC TM147-2016 to Staphylococcus aureus, Escherichia coli, and Candida albicans. It has been shown that QAC adsorption is different for different hydrophilic ammonium and pyridinum groups in a surfactant molecule. Ammonium group leads to higher adsorption, whilst pyridinium have better bonding. The antimicrobial results show similar behavior – pyridinium group QACs show better antimicrobial activity.
