Polyaniline Sn(IV) tungstomolybdate nanocomposite (PSTM) was synthesized by sol–gel method. Thephysico-chemical properties of PSTM were studied using FTIR, TGA, XRD, SEM, and TEM. The materialwas successfully used for the removal of Pb2+. Batch experiments were performed as a function of variousexperimental parameters such as effect of pH (2–8), contact time (5–60 min), initial Pb2+ concentration(10–30 mg L 1) and temperature (20–50 8C). The removal rate of Pb2+ using PSTM was fast andequilibrium established within 50 min. Kinetic studies showed better applicability for pseudo-firstordermodel. The values of thermodynamic parameters (DG8, DH8 and DS8) were also computed.
