Synthesis of sesbania gum supported dithiocarbamate chelating resin and studies on its adsorption performance for metal ions

Sesbania gum supported dithiocarbamate chelating resin (SGDSA) was prepared. The epoxy functional groups were introduced into sesbania gum to produce the sesbania gum supported resins and then reacted with triethylenetetramine, and lastly were converted to the respective dithiocarbamates by reacting with carbon disulphide. The structure of functionalized resins was characterized by FT-IR. The influences of various reaction conditions on the epoxidation were discussed. The prepared SGDSA exhibited high adsorption capacity for metal ions and the adsorption equilibrium could be arrived at shorter time.
