دانلود Separation of Toxic Metal Ions Such as Pb(II), Cu(II) and Hg(II) from Industrial Waste Water Using Newly Synthesised tinzirconium molybdophosphate Cation Exchanger

Abstract

A  novel  four  component  inorganic  cation  exchange  material  tinzirconium  molybdophosphate with  two  cations  and  two  anions  has  been  synthesized.  Chemical  composition  of  the  compound  was determined by ICP-AES  method and structural studies were carried out  using TGA, XRD, and FT-IR,SEM. Bifunctional behaviour of the material has been indicated by its pH titration curves. The material shows high ion exchange capacity of 1.96 meqg-1. The distribution coefficient studies of  metal ions on the material were performed in different solvent systems and the material was found to be selective for Pb(II),  Cu(II) and Hg(II) ions. On the basis of distribution coefficient value, some analytically important binary  separations  of  metal  ion  like  Pb(II)-Co(II),  Pb(II)-Ni(II),  Pb(II)-Mg(II),  Pb(II)-Hg(II),  Cu(II)-Bi(III),  Cu(II)-Zn(II),  Cu(II)-Mg(II),  Hg(II)-Zn(II),  Hg(II)-Bi(III),  Hg(II)-Mg(II)  were  achieved  ontinzirconium  molybdophosphate  column.  In  order  to  demonstrate  the  practical  utility  of  the  material, quantitative separation of Pb(II), Cu(II) and Hg(II) from textile effluent, paper industry and wood industry have been achieved.
