Abstract
A new chelating resin based on salicylic acid formaldehyde copolymer, containing hydroxamic acid as a functional group, has been synthesized and characterized on the basis of FTIR analysis, elemental analysis, and sorption capacity. The resin is highly stable in acidic and alkaline solutions and has been studied as a chelating sorbent for heavy metals. The sorption capacity order is: Cu(II)>Zn(II)>Pb(II)>Co(II)>Ni(II). The sorption for copper (II) was 1.80 mmol/g of dry resin. The distribution coefficients (Kd) for eight metal ions were determined in acetate buffers at pH=2, 4, and 6. The effect of nature and concentration of different electrolytes on Kd values for Zn(II), Cd(II), Cu(II), and Pb(II) has been investigated. The quantitative separations achieved on the column of the chelating resin include Co(II)‐Cu(II), Ni(II)‐Cu(II), Cd(II)‐Zn(II), and Pb(II)‐Cu(II). The resin columns were studied for the removal of iron (III) up to 0.0005% level in cobalt acetate and analysis of bauxite. The developed procedure was also tested for the removal and recovery of copper (II) and iron (III) from synthetic seawater.
