Evaluation of sorption and desorption characteristics of cadmium, lead and zinc on amberlite IRC-718 iminodiacetate chelating ion exchanger
A chelating type ion exchange resin (Amberlite IRC-718), containing iminodiacetate groups as active sites, has been characterized regarding the sorption and subsequent elution of Cd, Zn and Pb, aiming to metal preconcentration from solution samples of different origins. The methodology developed is...
