Hybrid clay-based nanocomposites possess outstanding physicochemical properties which enabled their successful utilization in various applications. In this work, we present a facile approach for the preparation of hybrid multifunctional clay/calixarene nanocomposite. This is based on the reaction between thiolated bentonite clay and alkynylated calix [4]arene through the UV radical-mediated thiol-yne addition. The as-obtained nanocomposite was characterized by the XRD, XPS, DRIFTIR, and NMR. The as-synthesized multifunctional clay/calixarene nanocomposite was used for removal of both Cd and Zn from the industrial waste-water. Interestingly, the complete removal of Cd and Zn was achieved within only 40 min, owing to the unique physicochemical merits of the clay/calixarene nanocomposite. In addition to the outstanding fast and great extraction capacity of clay/calixarene, it was fully maintained without any deterioration in the activity and/or dissolving for 10 cycles.
