Abstract
Natural chabazite Cha a natural zeolite has been used as carrier for two types of antibacterial agents namely silver Ag and Quaternary Ammonium Compound QAC Hexadecyltrimethyl ammonium bromide H. New antibacterial agents that have been prepared are AgCha HCha and HAgCha. The presence of Ag in Cha has been proven by Energy Dispersive X-ray EDX analyzer while the presence of both QACs molecules on Cha was detected by Fourier Transform-Infrared FTIR spectroscopy technique. The antibacterial activities of these samples were studied based on the determination of Minimum Inhibition Concentration MIC values in saline solution and distilled water against Bacillus subtilis. The higher antibacterial activity of sample is indicated by the lower MIC value. From MIC values chabazite containing Ag and QAC were able to kill bacteria compared to parent chabazite. HAgCha was found to have the highest antibacterial activity compared to other samples. It also could perform well in saline solution. Therefore it can be concluded that the combination of Ag and hexadecyltrimethyl ammonium bromide on natural chabazite carrier could become an alternative antibacterial agents.
