Green synthesis of Cts-Si and Cts-Si-Dtz has been carried out by combining enzymatic, chemical, and gamma irradiation methods. The synthesis of Cts-Si is based on the electrostatic interaction of the amine group in chitosan with the silanol group. The immobilization of dithizone in Cts-Si is based on thecomplexation of dithizone with silanol and acetamide groups. The Cts-Si and Cts-Si-Dtz have good ability as bioadsorbents of Fe(III), Cu(II), Pb(II), Cr(VI), and Cd(II). Adsorption with Cts-Si akes place through the electrostatic interaction of the amine group in chitosan with the silanol group. The interaction of Cts-Si-Dtz takes place through the chelation of metal ions with dithizone, silanol groups, and acetamide. Heavy metal adsorption is strongly influenced by solution pH, adsorbent mass, contact time, and concentration of metal ion solution. The kinetic model follows the pseudo 2nd order model and generally follows the Langmuir isotherm, although for some interactions it follows the Freundlich adsorption isotherm.
