Silver (I)-coordinated bis(trimethoxysilylpropyl)amine Polycondensate for Adsorptive Removal of Iodide from Aqueous Solutions
Silver-coordinated bis(trimethoxysilylpropyl)amine polycondensate (TSPA-AgNO3) was prepared and used to adsorb iodide ions in aqueous solutions. Batch adsorption studies were performed to investigate the effects of pH, temperature and coexisting NaCl on adsorption behavior. The results show that TSP...

| description | Silver-coordinated bis(trimethoxysilylpropyl)amine polycondensate (TSPA-AgNO3) was prepared and used to adsorb iodide ions in aqueous solutions. Batch adsorption studies were performed to investigate the effects of pH, temperature and coexisting NaCl on adsorption behavior. The results show that TSPA-AgNO3 is easy to prepare and remarkably efficient in adsorbing iodide in water, especially in acidic solutions. Furthermore, increased temperature accelerated the adsorption, while coexisting NaCl inhibited the adsorption. TSPA-AgNO3 also proved to be chemically stable in simulated environmental situations, which reveals a promising potential for applying this method to the disposal of radioactive iodide in environment water. |
