The adsorption process is the most suitable method for recovery of rare metals due
to its low cost, safety, and high efficiency. Because being insoluble in aqueous solution,
ordinary adsorbents for the recovery metal ions present two problems which are low
recovery efficient and low adsorption rate. In this study, water-swellable polymer is
synthesized that shows fast adsorption rate and high adsorption amount for rare metal
ions especially Cd2+, Pd2+, and Co2+
.
Three types copolymer - poly(allylamine-co-methacrylic acid(MAA)),
poly(allylamine-co-(2-(dimethylamino)ethyl methacrylate)(DMAEMA)), and vii
poly(allylamine-co-N-isopropylacrylamide(NIPAM)) - functionalized with acrylate
groups which have strong affinity to metal ions are synthesized. All components are
prepared in aqueous system and polymerized via free radical polymerization. The three
types of copolymer are well swelled in aqueous solution so that they are excellent
interaction with metal ions and show good adsorptive power. Adsorption of rare metal
ions is achieved based on the coordinating grafting of functional group complexes and
physisorption. Also ratio of 1
st
monomer to 2
nd
monomer was controlled, which effects on
the density of active site and adsorption power.
The morphology is confirmed by FE-SEM images. Adsorption sites are studied
through XPS analysis. Adsorption capacity of copolymer is analyzed by ICP-OES.
At the point of easy process and remarkable adsorption power, this study offers
facile adsorbents which are suitable alternatives for priori organic adsorbents
