Abstract

The aim of this study was to evaluate the adsorption of some hospital airborne microorganisms, e.g. Staphylococcus aureus check for this species in other resources , Streptococcos pyogenes check for this species in other resources , Pseudomonas aeruginosa check for this species in other resources , and Candida albicans check for this species in other resources by some inorganic nanoparticles. First, each microbial suspension (2 × 104 and 2 × 106 CFU/mL) was separately added to adsorbent columns (1 and 2 g), containing CaSO4, CaCO3, and FeSO4 nanoparticles. Then, the colony count reduction was measured for each adsorbent column. This study showed that all nanoparticles could adsorb all kinds of microorganisms. Importantly, the combination of CaSO4 and CaCO3 nanoparticles led to better adsorption property. Moreover, it was found that the adsorption was related to adsorbent weight and microbial density. The authors suggest that these adsorbent columns are good choice to remove hospital airborne microorganisms.
