COLLECTION OF MERCURY FROM AQUEOUS SOLUTIONS WITH CARBONACEOUS MATERIALS

抄録

The effect of pH on the collection of mercury(II) and methylmercury was investigated with nine commercially available carbonaceous materials. Specific surface area and C, H, O, N, and S in these materials were determined. Activated carbon (powder, granular, or felt) was the best adsorbent for mercury. Satisfactory recoveries were also obtained with carbon black from solutions of pH 1 to 14. In spite of the small specific surface area of anthracite, it gave fair recoveries of mercury.
