New terpolymer-matrix microcomposites for heavy metal removal

Abstract

Terpolymer/kaolinite microcomposites were synthesized by 2:2:1 molar ratio of the selected monomers, respectively using various proportions of kaolinite clay via in situ oxidative terpolymerization. The outcomes were confirmed by FT-IR and UV-Vis spectra of terpolymers/kaolinite microcomposites. The thermal behaviour of the terpolymer microcomposites was examined and compared with the pristine terpolymer. SEM of terpolymer microcomposite was recorded at varied magnifications and was affirmed microcomposite granules spread out through the area including sizes from 0.06 μm to 0.70 μm. From DLS results, narrow PDI value of the terpolymer in the microcomposites suggests the narrow molecular weight distribution. This study demonstrates that terpolymers/kaolinite microcomposites particles could be represented as potential adsorbents for dangerous and perilous metal ions from water. Each of Cd(II), Cu(II) and Pb(II) caused a serious health problem in our day-to-day life.
