Istnieje duże zapotrzebowanie na badania nad detoksykacją nanoodpadów i recyklingiem zużytych nanosorbentów. W niniejszym artykule dokonano przeglądu badań prowadzonych w tej dziedzinie przez naszą grupę. Przetwarzanie nano-Mg(OH)₂ z ładunkiem Cr(VI) stanowi nową strategię zagospodarowania nanoodpadów. Nanoodpady zostały przetworzone w nietoksyczny materiał masowy i stężony roztwór zawierający Cr(VI) na drodze szybkiego wzrostu nanokryształów, który spowodował desorpcję i całkowite oddzielenie Cr(VI) od substancji stałej. Stężony roztwór Cr(VI) można poddać recyklingowi przemysłowemu, a oczyszczony produkt stały można stosować w produkcji materiałów ceramicznych, powłok do metali i ognioodpornych tworzyw sztucznych. Przedstawiono też strategię recyklingu nanosorbentu Mg(OH)₂ do stosowania go do usuwania Cr(VI) z roztworów o małym stężeniu Cr(VI).

There is a strong demand for the investigations on the detoxification of the nano-wastes or recycling of the loaded nanoadsorbents. This article reviews the studies of our group in this field. The treatment of Cr(VI) loaded nano-Mg(OH)₂ introduces a new strategy for nano-waste disposal. The nano-wastes were converted into a nontoxic bulk material and a concentrated solution containing Cr(VI) by the rapid growth of nano-cystals which leads to the desorption and complete separation of Cr(VI) from the solid. The concentrated Cr(VI) solution can be recycled in the industry and the detoxified solid product can be reutilized in ceramics, metal coatings or flame-retardant plastics. Finally, a recycling strategy of Mg(OH)₂ nano-adsorbent was provided for the enrichment of Cr(VI) from aqueous solutions of low-concentration Cr(VI).
