Abstract: When other nutrients were sufficient in cultivation of the thiobacillusferrooxidans, the effect of mass concentration of activated carbon on the growth activity of thiobacillusferrooxidans was studied, and the bacterial growth curves were obtained at different activated carbon mass concentrations. The experimental results showed that the activated carbon can promote the oxidative activity of thiobacillusferrooxidans in a certain concentration range. When the activated carbon concentration is less than 80g/L, it has a promoting effect on bacterial oxidative activity; when the concentration is 60~80g/L, the promoting effect is the biggest; when the concentration is larger than 100g/L, the growth of thiobacillusferrooxidans is completely inhibited. By researching the timevariation of ρ(Fe2+) and ρ(Fe3+) during the sterile control experiment, the results showed that the activated carbon has little effect of oxidation on Fe2+when the activated carbon concentration is less than 80g/L.

Key words: thiobacillusferrooxidans, oxidative activity, activated carbon, adsorption, catalytic oxidation
