Adsorption Characteristics of Impregnated Adsorbent for Mercury Removal

Significant amounts of fluorescent light have been discarded every year. Mercury is released into the atmosphere in the recycling process of it, if improperly treated. The adsorption method is used to remove mercury discharged from the recycling step of fluorescent light.We studied the impregnation condition of adsorbent made from sewage sludge. And also adsorption characteristics of mercury were evaluated by impregnated adsorbent.According to our results, the adsorption efficiency of mercury was increased by impregnating adsorbent with chlorine and iodine. The adsorption capacity was described by Langmuir isotherm model.
