Equilibrium and kinetics of heavy metal ion exchange
Ion exchange has a great potential to remove heavy metals from industrial wastewaters or heavy metal-containing sludge. In order to design and operate heavy metal removal processes, the equilibrium relationship between ions and resin must be known a prior. A series of ion-exchange equilibrium tests of Cu/H, Zn/H, and Cd/H systems using Amberlite IR-120 were performed. The equilibrium data were ...
متن کاملSupported Liquid Membrane in Metal Ion Separation: An Overview
Using liquid membrane and, in particular, supported liquid membrane (SLM) is a novel method of separation in comparison to other methods such as adsorption, extraction and ion exchange. SLM is a combination of simultaneous extraction and disposal whose high efciency and capability is proven by many studies. So far, many researchers have utilized SLM in various scientifc...
متن کاملIon Exchange Adsorption of Molybdenum with Zeolitic Adsorbent
Zeolitic adsorbents have been developed for molybdenum recovery from various sources. The batchwise adsorption ability of molybdenum ion (Mo) with zeolite A type adsorbent could be improved when the counter cation (Na) was exchanged by divalent ions (Sr and Ca), while no significant difference was observed in the case of zeolite X type adsorbent. The adsorption ability for Mo was therefore base...
متن کاملNanofiber Ion-Exchange Membranes for the Rapid Uptake and Recovery of Heavy Metals from Water
An evaluation of the performance of polyelectrolyte-modified nanofiber membranes was undertaken to determine their efficacy in the rapid uptake and recovery of heavy metals from impaired waters. The membranes were prepared by grafting poly(acrylic acid) (PAA) and poly(itaconic acid) (PIA) to cellulose nanofiber mats. Performance measurements quantified the dynamic ion-exchange capacity for cadm...
