ABSTRACT:
Mercury present in liquid effluents, for example, the effluent from a caustic-chlorine plant using a flowing mercury cathode, is removed by first converting the mercury to a metallic or soluble form and thereafter contacting the solution with tin-coated iron strips having tin-iron interfaces in contact with the solution. The invention also is applicable to the recovery of mercury from existing accumulations in water body sediment.
