This work reports a study towards a search for environmentally friendly water disinfectant. The most common method for water treatment is based on chlorine which had a wide application over the years as a water disinfectant, but suffer the disadvantage of reacting with natural organic matter to form disinfection by products. In this study, the potential application of novel ferrocenylimines compounds, namely 4-ferrocenylaniline (1), N-(3-bromo-2-hydroxylbenzylidene)-4-ferrocenylimine (2) and N-(3-bromo-5-chlorosalicyl)-4-ferrocenylimine (3) for the elimination of bacteria in water was investigated by evaluating their antibacterial properties against twelve different bacterial strains using microdilution method in sterile 96 well micro titer plates. The in vitro antibacterial activity revealed that the ferrocenylimines compound exhibit higher antibacterial activity than ferrocene, which is one of the starting materials towards the synthesis of this novel ferrocenylimines compounds. The most active ferrocenylimines compound was compound 3 with a minimal inhibitory concentration (MIC) value of 0.30 mg/ml against S. sonnei. In addition, all the ferrocenylimines compounds possessed excellent antibacterial activity against B. cereus with the same MIC value of 0.31 mg/ml. The results obtained so far show great potential in the three tested ferrocenylimines compounds for use in water treatment in killing bacteria in water.
