    • Abstract


      A new surfactant supported cation exchanger and adsorbent named, polyoxyethylene octyl phenyl ether supported thorium(IV) phosphate (TX-100ThP) has been reported along with its synthesis, physico-chemical characterization such as scanning electron microscopy, X-ray diffraction, thermogravimetric analysis–differential thermal analysis and Fourier transform infra-red study. Following the characterization, the formed product has been tested for its efficiency in ion exchange chemistry and in analytical chemistry. For the testing, adsorption of alkaline earths—Mg$^{2+}$, Ca$^{2+}$, Sr$^{2+}$ and Ba$^{2+}$ and transition metal ions such as Fe$^{3+}$, Mn$^{2+}$, Ni$^{2+}$, Cd$^{2+}$, Co$^{2+}$, Cu$^{2+}$, Hg$^{2+}$ and Pb$^{2+}$ have been explored in different acidic media and the results revealed the selectivity of synthesized material towards Hg$^{2+}$ ions. On that basis, the material has been used to treat the binary laboratory-made samples, exploring the environmental importance of the cation exchanger in material science.
