| Abstract: |
| This work reports the adsorption behaviour of dithiooxamide/glutaraldehyde resin (R-DTGA) polymer towards Hg(II) removal from contaminated aqueous and industrial-waste media. The synthesized polymer has been characterized using the X-ray diffraction, energy dispersive X-ray spectroscopy, Fourier-Transform Infrared spectroscopy, and DTA/TGA measurements. The adsorption of mercury was performed using the Batch technique. The Batch-experiments were carried out using the synthesized polymer and the effect of various parameters on Hg(II) ions removal has been investigated. The studied parameters are solution pH, Hg(II) ions concentration, and adsorption time. The obtained results and data indicated that the Hg(II) ions adsorption was powerfully-submissive to the pH value (4.6) and appeared to best fit the Langmuir adsorption model with pseudo second order kinetics. The studied adsorbent gave a superior maximum uptake capacity of 11 mmol/g. Based on our results, the synthesized polymer provided extraordinary maximum capacity, selectivity, reusability, sensitivity, and fast adsorption kinetics to remove and recover mercury ions from industrial, aqueous, and wastewater solutions. |
