Efficient simultaneous removal of cadmium and arsenic in aqueous solution by titanium-modified ultrasonic biochar
Abstract
A novel titanium-modified ultrasonic biochar was synthesized. The BCTD showed extraordinary simultaneous removal of aqueous Cd(II) and As(V). The maximum adsorption capacities of Cd(II) and As(V) were 72.62 and 118.06 mg/g. The removal of Cd(II) and As(V) had a competitive effect at above 100 mg/L. Simultaneous removal of aqueous Cd(II) and As(V) mechanism were identified.
