Study on adsorption of fluorine and arsenic in water by coal cinder

doi:10.7523/j.issn.2095-6134.2014.04.005

Abstract

Abstract:

The adsorption characteristics of coal cinder to fluorine and arsenic were studied with static adsorption experiments, and the influences of oscillation time, sorbent dosage, initial concentration, and pH on the adsorption characteristics were investigated. The results show that in the optimal processes sorbent dosage is 6 g and adsorption time is 3 h. Adsorption of fluorine by coal cinder is more effective at higher concentration of fluorine than at lower concentration. However, adsorption rates of arsenic are always more than 95%,whatever the initial concentrations. The acidity has little influence on the adsorption characteristics of fluorine and arsenic.

Key words: coal cinder, fluorine, arsenic
