    2018-10-20  The magnetic adsorbent has a unique separation property that renders it an excellent adsorbent for heavy metals and it can be readily removed/recovered from solutions (Gomez-Pastora et al., 2017; Zhou et al., 2016). Bare Fe 3 O 4 was shown to be potentially useful to remove heavy metals at a capacity of 73 mg/g (Mahdavi et al., 2012).

  • Thallium - cs.mcgill.ca

    Thallium (IPA: /ˈθaliəm/) is a chemical element in the periodic table that has the symbol Tl and atomic number 81. This soft gray malleable poor metal resembles tin but discolors when exposed to air. Thallium is highly toxic and is used in rat poisons and insecticides but since it might also cause cancer (although the EPA does not class it as carcinogen), this use has been cut back or ...
