This study presents a comprehensive approach using PET bottle waste and UiO-66 framework technology to remove toxic insecticides from water, with technical advantages including sustainable and inexpensive preparation, high adsorption capacity and rate, stability, and recyclability.
The continually growing level of ecotoxicants generates a request for principal new strategies to safeguard the environment. In this contribution, we proposed a comprehensive approach to solving two emerging problems: recycling polyethylene terephthalate wastes (PET) and removing toxic insecticides from water. The developed technology consumed PET bottles as the source and support for the growth of UiO-66 frameworks and were further applied for the removal of imidacloprid from water. The prepared material was characterized by a range of microscopic and spectroscopic techniques confirming the high loading and homogenous distribution of UiO-66 across the PET support. The sorbent (PET@UiO-66) delivered considerable technical advantages beyond the convenient sorbents: sustainable and cheap preparation; high adsorption capacity and rate; stability and recyclability; 100 times enhanced permeability compared to UiO-66 powder; and applicability in fixed-bed columns. We believe that the proposed design and technological relevance will be a basis for the further developing of the smart utilization of wastes for sustainable functional materials. ? 2020 Elsevier Ltd.
