Application of Polythiophene Nanocomposite Coated on Polystyrene and Poly(Vinyl Chloride) for Removal of Pb(II) from Aqueous Solution

Abstract

Poly(vinyl chloride) (PVC) and polystyrene (PS) particles were coated with polythiophene (PTh) by using chemical oxidative polymerization method in the presence of iron chloride (III) and their capability to removal of Pb(II) from aqueous solution was studied. These nanocomposites were characterized by FTIR, SEM and TGA. Batch study was performed to evaluate the influence of various experimental parameters such as pH, water pollution dosage and contact time on the removal of Pb(II). Comparison between nanocomposites showed PTh/PS has better thermal stability than PTh/PVC. Also, results indicated that the removal of Pb(II) was better when PTh/PVC was used as adsorbent.

“…Such composite materials exhibit not only a super paramagnetic property but also useful electrical [2][3][4] or optical properties [5] offering potential applications in numerous areas such as information storage [6] , electromagnetic interference shielding [7,8] , antistatic coating [9][10][11] , gas sensors [12,13] , optical devices [14] , removal of heavy metals [15][16][17] , and so forth.…”

Efficient removal of Pb(II) ions from aqueous solution by using a novel functionalized bio‐material with two tridentate coordinated units

“…Lead (Pb) is one of the harmful pollutants, and it can damage the central nervous system and reproductive system of human beings and animals 5,6 . Therefore, searching for effective techniques to remove Pb(II) ions from the environment requires enormous effort from researchers 7,8 …”
