چکیده انگلیسی
Ethylene diamine tetraacetic acid (EDTA) and sodium dodecyl sulfate (SDS) were employed to impregnate activated carbons for the purpose of lead removal. The mechanisms of surface impregnation and lead adsorption method of chemical regeneration were investigated. Results showed that the highest impregnation of EDTA and SDS on activated carbon was 0.33 and 0.96Â mmol/g, respectively. Adsorption capacities for lead of EDTA and SDS impregnated activated carbons reached 0.29 and 0.24Â mmol/g. Rapid small scale column tests of adsorption and regeneration were conducted. Lead adsorption was greatly enhanced by EDTA impregnation. In addition, EDTA impregnated adsorbent was able to be successful regenerated by HNO3 and thus reused.
