| Abstract: | The adsorption of sulfide in waste water by TiO_2 was studied. The effects of different substances,time, solution pH and input ratio on the adsorption of sulfide from aqueous solution were investigated. The experimental results showed that TiO_2 has a certain adsorption effect on sulfide in wastewater. The optimum modifier was NaOH, the optimum time was 5 h, the optimum temperature was 40 ℃, the optimum solution pH was 8 and the optimum input ratio was 80 g/L. |
