主 题：nanomaterial environment pollutants heavy metal nanoparticles fast growth reutilization
摘 要：The environmental behavior, biological and ecological effects of nanomaterial have attracted much attention, and nanomaterial is prevalently used in the process of industrial manufacturing. However, the investigation on how to resolve the environmental problems of nanowastes is scarcely reported. We have proposed a novel method in which the toxicity of the waste is reduced during the fast growth of nanoparticals. It is suggested that this method could be used in the treatment of the Cr(VI)-containing nanowastes from the chlorate plants. In this work, the efficiencies of the treatment at both room and high temperatures were further studied. The craft route is advanced for the treatment at the high temperature. The phase, morphology, size, and thermal behavior of the detoxified solid were analyzed by XRD, SEM, and DTA. The solid was also tried as the raw of glaze. The disposal provided here will be a good example for the recycling of the hazardous nanowastes.
