Cysteine methyl ester modified glassy carbon spheres for removal of toxic heavy metals from aqueous media

摘要

Glassy carbon spherical powder (10-20 mu m diameter) modified with cysteine methyl ester is found to be an inexpensive, novel material for the rapid removal of large quantities of toxic heavy metal ions such as Cd(II), Cu(II) and As(III) from aqueous media, with wide ranging potential applications such as third world drinking water filtration or environmental cleanup.
