Chemical activation and microwave assisted activation were adopted to modify biochar. Activated biochars were characterized by SEM, BET, FTIR, XRD and XPS. Raw biochar, activated biochars and commercial activated carbon were compared as remediation strategies for sediment from the Xiangjiang River containing 14.70 mg/kg Cd. After the treatment by activated biochar, the overlying water and pore water...
With growing interests in the applications of high aspect ratio (AR) ZnO nanomaterials (NMs), their potential toxicity to human health and nature environment remains a critical concern because these NMs have extremely large specific surface area (SSA) that could dramatically enhance interactions between NMs and surrounding molecules. In addition, originated to their intrinsic photocatalytical activity,...
