Tóm tắt

The amount of iron (III) hydroxide released f-rom waste water treatment of metal plating industry inVietnam is extremely large, up to several thousands tons per year, however most of them are notrecycled or re-used. In this work, we have investigated the static adsorption of sulfide on waste sludgeFe(OH)3 f-rom metallurgic factories and the ability to use this material for sulfide removal f-rom pollutedwater. The following optimum conditions include pH 6.0, equilibrium time 4 hours; mass of adsorbent0.1 g. The maximum adsorption capacity is reasonably high, qmax= 27.8 mg/g. pH and other co-existingions do not significantly influence the adsortivity of material. We applied this adsorption procedure toprocess 04 surface water samples in Hanoi that are seriously pollutedwith sulfide. Results show that theconcentration of sulfide after treatment was lowered below the allowance level regulated by TCVN142008.
