Highly selective colorimetric detection and preconcentration of Bi(III) ions by dithizone complexes anchored onto mesoporous TiO(2)

We successfully developed a single-step detection and removal unit for Bi(III) ions based on dithizone (DZ) anchored on mesoporous TiO(2) with rapid colorometric response and high selectivity for the first time. [(DZ)(3)-Bi] complex is easily separated and collected by mesoporous TiO(2) as adsorbent...

description We successfully developed a single-step detection and removal unit for Bi(III) ions based on dithizone (DZ) anchored on mesoporous TiO(2) with rapid colorometric response and high selectivity for the first time. [(DZ)(3)-Bi] complex is easily separated and collected by mesoporous TiO(2) as adsorbent and preconcentrator without any color change of the produced complex onto the surface of mesoporous TiO(2) (TiO(2)-[(DZ)(3)-Bi]) at different Bi(III) concentrations. This is because highly potent mesoporous TiO(2) architecture provides proficient channeling or movement of Bi(III) ions for efficient binding of metal ion, and the simultaneous excellent adsorbing nature of mesoporous TiO(2) provides an extra plane for the removal of metal ions.
