Super rapid removal of copper, cadmium and lead ions from water by NTA-silica gel

Super rapid removal of copper, cadmium and lead ions from water by NTA-silica gel

Copper (Cu 2+ ), cadmium (Cd 2+ ) and lead ions (Pb 2+ ) are toxic to human beings and other organisms. In this study, a silica gel material modified with nitrilotriacetic acid (NTA-silica gel) was sensibly designed and prepared via a simple amidation procedure for the removal of Cu 2+ , Cd 2+ and P...

Zusammenfassung:Copper (Cu 2+ ), cadmium (Cd 2+ ) and lead ions (Pb 2+ ) are toxic to human beings and other organisms. In this study, a silica gel material modified with nitrilotriacetic acid (NTA-silica gel) was sensibly designed and prepared via a simple amidation procedure for the removal of Cu 2+ , Cd 2+ and Pb 2+ from water. The NTA-silica gels showed rapid removal performances for the three metal ions (Pb 2+ (
