The present study is contributed to the removal of excess fluoride in drinking water using cerium dispersed in carbon (CeDC), a hybrid sorbent which was prepared by carbonization of ammonium cerium sulfate impregnated starch. One synthesized CeDC sample with a specific surface area of 685cm 2 g −1 was investigated for its fluoride scavenging ability as the function of pH, fluoride...
The paper presents a detailed study of the effect of manganese dioxide on the defluoridation potential of disposed earthenware (DEW) of the particle size less than 300μm. Manganese dioxide was added to DEW with weight content from 0.01 to 0.025%. The defluoridation was investigated in static experiments, at pH 5–11 and with contact time of 35min. The fluoride removal increased with the increasing...
