The research's purpose is to prepare inorganic antimicrobial of CuxSy for the continuous deodorization system at higher temperature than 60℃. The preparation of inorganic antimicrobial of CuxSy was as follows; Copper(Ⅱ) sulfate pentahydrate 100g and sodium sulfate 70g were dissolved in distilled water 250mL, respectively. Mixing these solutions and stirring for 30min, particles of CuxSy were synthesized in the process. The obtained particle was washed repeatedly with distilled water to pH 6~7. The washed particle was dried at 50℃ for 1h and then, calcinated at 200℃ for 2h, finally. Analyzing of the particle by XRD, XRF, and TGA, it is shown that crystal peaks are (101), (102), (103), (006), (110), and (018), mole ratio of Cu/S is about 2.4, and pyrolysis temperature is about 300℃. Evaluating antibiosis by Staphylococcus aureus ATCC 6538P, antibiosis was favorable in concentrations over 1 wt% CuxSy.
