Abstract Iminodiacetate cellulosic chelating sorbent, derived from cotton fabric, was synthesized in a two‐step reaction sequence. The pH dependence of the metal ion extraction for Cd (II), Co(II), Cu(II), Pb(II), and Ni(II) was studied. Under optimum conditions, the average sorptive capacity of the sorbent was found to be 0.38 mmol metal ion/sorbent. The viability of using this sorbent for recycling, preconcentration of metal ion, and selective metal ion extraction was demonstrated.
