Mercury removal

Scientists at Flinders University (Adelaide, Australia; www.flinders.edu.au) have further characterized their sulfur-limonene polysulfide polymer (Chem. Eng., December 2015, p. 12) to understand the conditions under which it can be used as a mercury sorbent. In a recent issue of Physical Chemistry Chemical Physics, the researchers have demonstrated that silica covered with an ultra-thin coating of poly(S-r-limonene) can, in some cases, capture 99% of mercury (HgCl2) from water within minutes. The polymer is effective over the pH range from 3 to 11. The material is also selective for binding mercury, but not other metal contaminants, such as iron, copper, cadmium, lead, zinc and aluminum. When salt is added to mimic seawater, the mercury uptake rates and capacity are dramatically reduced.
