Abstract
The adsorptive performances of PET waste are very low, for most of metal ions and dyes from aqueous media, and from this reason their use as adsorbent in the environmental remediation processes, is inefficient. Increasing the adsorption capacity of PET waste involves improving of the number of superficial functional groups, and this can be generally done by the functionalization with certain chemical compounds. But most of functionalization procedure also implies the dissolving of PET waste in a suitable solvent, which is not so easy. In this study, two phenolic compounds (phenol and p-chloride-phenol) have been used for the dissolution and functionalization of PET waste, to obtain new adsorbent materials with applications in the environmental remediation. The preparation of these two adsorbent materials were detailed discusses to highlight the main advantages and disadvantages of each. Also, their adsorptive performances have been tested in case of Cu(II) ions removal from aqueous media. The experimental results have shown that the functionalization of PET waste with these organic compounds increase the adsorption efficiency of obtained materials for Cu(II) ions with more than 200% in case of PET waste functionalized with p-chloride-phenol and with more than 350% in case PET waste functionalized with phenol. This significant increase in adsorption capacity opens up new perspectives in the use of PET waste as adsorbent material for the removal of heavy metal ions from aqueous media.
