More recently, Peraniemi et al. [229] advocated the use of zirconium-loaded activated charcoal as an effective adsorbent for mercury (and especially for arsenic and selenium), the rationale being that the presence of active metal on an impregnated charcoal surface can greatly affect the adsorption affinity. They compared the pH effects on the uptakes by both a loaded and an unloaded commercial charcoal powder and concluded that the adsorption mechanism of mercury differs from that of the anionic arsenic and selenium species. They also noted the highly complicated behavior of mercury in aqueous solutions and did not attempt to explain the apparent absence of pH dependence of the uptakes.
