Abstract
An ion exchange resin chelator was synthesized from 8-hydroxyquinoline and pyrogallol using formaldehyde as a crosslinking agent to 120°C in a solution of DMF. The resin was characterized by elemental analysis and FTIR. The morphology of the synthesis resin was examined by optical photograph and scanning electron microscopy (SEM). The physicochemical properties of the resin were studied. The cation exchange capacity was measured and the effect of pH and metal ion concentration on the ability of the ion exchange were studied. The ratio of cation exchange reaction and the distribution coefficient in tartaric acid medium at different pH were also studied using the method of batch equilibration.
Highlights
Over the past years, there has been a growing concern for the immobilization of metal ions introduced into bodies of water and wastewater by increasing human technological activities
The extraction of metal ions using ion exchange resin is a chelating power green analytical method, since it does not involve the use of toxic organic chlorine compounds, which are very frequently used in conventional techniques liquid-liquid extraction
The results show that the sorption metal ions is increased with increasing pH to a maximum value and thereafter decreased
Summary
There has been a growing concern for the immobilization of metal ions introduced into bodies of water and wastewater by increasing human technological activities. It has been established beyond doubt that the ions of heavy metals in the environment (air, soil and water) pose a serious threat to human health. With the exponential growth of the population, it is necessary to control the release of toxic heavy metal ions before entering the complex ecosystem. The solid phase extraction on the metal ion was granted fast acceptance due to its various advantages over other the invention provides methods. The extraction of metal ions using ion exchange resin is a chelating power green analytical method, since it does not involve the use of toxic organic chlorine compounds, which are very frequently used in conventional techniques liquid-liquid extraction
