| Summary: | Aims of the present work are to investigate the photomineralization of commercial humic acid
in water solution.The effect of initial pH of solution and different anions (chloride, sulfate and mixture)
on the photocatalytic degradation of HA with titanium dioxide in aqueous solution has been examined.
The photocatalytic mineralization rate in alkaline solution is lower than in neutral and acidic solution. In our
conditions no effect of chloride ions on the degradation rate is observed. The influence of the sulfate depends
on its concentration in the solution. For a large concentration, we note a decrease of the mineralization
rate. |
