Overview

Randomized trial evaluates efficiency of two ion-exchange resins for cadmium removal in water, indicating their potential for regeneration.

Key Points

  • This research aims to compare the cadmium ion removal efficiency of two different chelating ion-exchange resins.
  • Batch experiments were conducted to evaluate resin performance at varying dosages, pH, temperature, and contact times.
  • Kinetic and equilibrium data were analyzed using pseudo-second-order and Langmuir models, respectively.
  • Thermodynamics evaluated the spontaneity and nature of cadmium removal.
  • Complete cadmium removal achieved under optimized conditions for both resins.
  • Maximum exchange capacities were 201.33 mg/g for MTS9300 and 191.44 mg/g for MTS9500 at 30 °C.
  • Regeneration efficiency of both resins was nearly 100% using HCl and H2SO4 solutions.
