Greener Procedure of Dithizone Immobilization on Coal Bottom Ash for Heavy Metal Adsorbent: Synthesis Optimization and Characterization

Abstract:

In the present study, new greener approach of dithizone immobilization on coal bottom ash as a source of silica-alumina materials in alkaline (NaOH) solution has been developed to replace previously used method utilizing more toxic solvents such as toluene, carbon tetrachloride or chloroform. Some parameters influencing the effectiveness of dithizone immobilization including reaction time, concentration of NaOH solution as well as washing procedures were optimized. FTIR (Fourier Transform Infra-Red), XRD (X-Ray Diffraction) and DSC/TGA (Differential Scanning Calorimetry/Thermogravimetric Analysis) analysis were employed to characterize the obtained materials. The adsorbents also tested for the adsorption of Pb(II) ion. Results suggest the use of greener alkaline medium has doubled the effectiveness of dithizone immobilization on the surface of coal bottom ash and hence enhances the capacity and selectivity of adsorbent towards heavy metals.
