In the present study, a novel and rapid extraction method using Extractant Impregnated Resin (EIR) prepared by
impregnating Amberlite XAD-4 resin with Isonitroso-4-Methyl-2-Pentanone (IMP) was evaluated for separation and
spectrophotometric determination of Zr4+ with arsenazo III at 670 nm. The optimization of various parameters
influencing the sorption of Zr4+ in column and batch methods was carried. Zr4+ was quantitatively sorbed at pH 3.5
and recovered 99.2 ± 0.6% using 10 mL of 0.1 M oxalic acid as eluent in column method. The pre-concentration
factor 200 with breakthrough volume 2000 mL and reusability up to 90 cycles were achieved with EIR. Experimental
data were evaluated using the kinetic and isotherm models to explain the sorption mechanism of Zr4+ by EIR. The
sorption equilibrium and kinetic data were be.. View more»
