| Abstract | ||
| Bentonite is well known as an absorbent and is an effective agent in separating and binding heavy metals, drugs, bacteria and other toxins from the body. In this study, the effect of pH changes (pH 3, 4 and 5) on the absorption and desorption of Staphylococcus aureus to sodium bentonite was investigated. In addition, by mixing sodium bentonite with S. aureus the bacterial count reduction at different time intervals (0, 30, 60 and 90 minutes) was recorded by direct culture and determining CFU/ml. At each mentioned time interval the changes were recorded. The relation between pH and bacterial absorption to bentonite appeared significant only at pH=5 . The reduced absorption of bacteria to bentonite with increasing pH was a linear diagram. There was no significant correlation between pH and time. As well as, average multiple comparisons with Duncan's test showed that, no significant bacterial count reduction occurs after 30 and 60 minutes while after 90 minutes this reduction is highly significant reaching almost zero and complete inhibition of bacterial growth | ||
