- Abstract
In this paper, neodymium removed by liquid-solid extraction is made by magnetic nanoparticles functionalized by the poly(aminoethylene N-methyl 1-formic acid, 1-phosphonic acid) (PAEMFP), with two different sizes. For a quantity of 0.01 g of magnetic particles some parameters were studied. Optimal extraction yield was achieved in a initial pH equal at 7.0 for fine particles and pH 6.0 for the large particles. The experimental capacity obtained was 25 mg g for larges particles and 23 mg g for fines particles. The quantitative elution study of neodymium(III) can be realized with acetic acid 0.5 mol L after 120 min of shaking for two sizes.
