Abstract
A highly sensitive ratiometric fluorescent assay for the detection of Cd2+ in water using metal coordinating polymer namely Indole functionalized polysulfone has been developed. Indole molecule has been introduced into the commercially available polysulfone through formation of imine linkage between indole-3-carboxaldehyde and aminated polysulfone. The indole functionalized polysulfone exhibited a fluorescent emission with a peak maximum at 391nm and 420nm, the intensity of the emission at 391nm is increased proportional to the addition of Cd2+ ions. The lowest detection limit for the Cd2+ has been found to be 2.4 nm. Further, the adsorbent capacity of the indole functionalized polysulfone has been evaluated at various pH. It is observed from the results that the adsorbent effectively adsorbs Cd2+at basic pH, and capable of removing 0.179g of Cd2+/g of polymer.
