Abstract：A mercaptan-containing resin, DMO-M, with high redox capacity- 6.00 mequiv / g, prepared by reacting mercaptoacetyl chloride with the aminophenol resin Duolite A-7 in free-base form has been used to remove mercury in dilute aqueous solution. The resin has high mercury removal capacity; 1200mg/g. Sodium chloride affects the equilibrium sorption of mercury on the resin. At lower pH values, below 1.76, mercury sorption of the resin was greatly reduced. The sorbed mercury is partially removed by 2?mol/L HCl sol...

Key words：Mercaptan-containing resin; mercury; sodium chloride; striping
