Modified Cellulose Adsorbent for Removal of Mercury from Aqueous Solutions.
Environmental Sci and Technol 1974 Nov; 8(12):4 pages
Scavenging inorganic mercury from aqueous solutions has been accomplished by a modified cellulose adsorbent containing vicinal thiol groups. The process is highly selective for mercury, is independent of ph over the range from ph 1 to ph 9, and is effective in acidic brine. A solution containing 1 ppm mercuric ion was passed through a column (10 mm id by 23 mm) prepared from 0.5 Gram of the cellulose derivative. Mercury concentration in the effluent was dependent upon the flow rate of the solution; however, at 50 ml/hr, the effluent mercury concentration remained below 5 ppb for 60 bed volumes.
