TLDR
In this article, a polymeric ligand exchanger was used for the treatment of water containing mainly chromium by an in-house synthesized specific amphoteric chelator, which achieved minimum and maximum level sorption of 41.2% and 99.6% at feed concentration of 50 and 500 ppm respectively.Abstract:
The present solid phase sorption studied for the treatment of water containing mainly chromium by “In-house” synthesized specific amphoteric chelator have been evaluated w.r.t. basic parameters like concentration, time, and elution etc. High uptake values of the metal ions proves its selectivity, whereas negligible elution or high immobilization factor (0.97) confirm further decontamination of run-off water during natural calamities. This polymeric ligand exchanger displayed minimum and maximum level sorption of 41.2% and 99.6% at the feed concentration of 50 and 500 ppm respectively.read more
