Özet:

In this work, CdSe nanocrystals based on heavy metals are synthesized with organometallic precursors at high temperature and it is aimed to use a new nanocomposite microcapsule adsorbent material for Cr (VI) removal from water by preparation of chitosan-doped microcapsules. Structural analyzes of synthesized CdSe nanocrystals were performed by transmission electron microscopy (TEM) and X-ray diffraction (XRD) measurements. The adsorption capacities of the microcapsules, initial metal ion concentrations, pH, time and adsorption effects of adsorbent dose were investigated in order to remove Cr (VI) ion from aqueous solutions according to the Batch method. In Cr (VI) metal-sorption processes, equilibrium sorption isotherm curves were drawn by using Freundlich and Langmuir sorption isotherms and the adsorption parameters were calculated from these isotherms.
