摘要：

Sludge of tap water production was modified by iron nanoparticles via borohydride reduction in ferric chloride as an adsorbent for arsenic removal from contaminated water. Factors affecting the adsorption of As(III) and As(V) were studied. The maximum adsorption capacity was 24.2 and 35.7mg/g for As(III) and As(V), respectively. The modified sludge with 10% (w/w) iron was effective for As(III) and As(V) removal from wastewater, surface water, and groundwater. The arsenic-contaminated sludge was stabilized/solidified using cement. The leaching study of arsenic by the dynamic monolithic leaching test (DMLT) showed that arsenic was mildly leached from the solidified adsorbent.
