Abstract
Fe-Ti cross-linked organic-montmorillonites were synthesized to treat simulation wastewater.The properties and optimal conditions for modified montmorillonites to absorb COD from simulation wastewater were investigated in detail using orthogonal experiments. The optimal conditions were pH=5, the amount of absent 10 g/L, stirring 40 min. The results indicated that removal percentage of COD was over 80 %. The result was satisfied.
