| Abstract | ||
| Carbohydrazide functionalized cellulose (CH-MC) was prepared and characterized using some qualified techniques such as Scanning Electron Microscopy (SEM), Infra-Red (FT-IR), Elemental analysis (EA) and Thermogravimetric analysis(TGA) . The prepared CH-MC was employed for uptake of heavy metal ions such as, Hg2+and Cu2+ from different samples. Sorption parameters: such as pH, temperature, time of sorption and the concentration of sorbent were investigated to determine the best conditions for sorption. The kinetic of sorption agreed with the second-order model and the chemical adsorption is the rate-limiting step. In addition, the sorption isotherm experiments revealed that the best adequate with Langmuir model which the maximum adsorption capacities for Cu2+and Hg2+ metal ions on CH-MC are 43.3 and 64 mg/g, respectively. The real samples including Hg2+ and Cu2+were used for analytical applications on the present methodology and the observed data is promising. | ||
