Article Preview

In the treatment of wastewater, the Fe- Ti Modified Bentonite was prepared as a new type of absorbing material which raw material was sodium bentonite. The Fe- Ti Modified Bentonite was used in the simulation wastewater which included Cr6+ and organic matter. The best adsorption condition was ensured by the pH value, the dosing quantity and the absorption time. The results of these experimental dates showed that the Fe- Ti Modified Bentonite had an excellent absorption performance and was much better than the sodium bentonite. The removal rate of Cr6+ and COD were 98.56% and 78.23% respectively if the pH value was 3, the dosing quantity was 10 g/L , the absorption time was 30 minutes. The results also showed that the distance of the modified bentonite was changed because the cross-linking agent entered the layers structure. That was why the absorption performance of Fe- Ti Modified Bentonite was improved.
