Abstract: The invention provides a bound sulfided metal containing metals such as nickel, cobalt, iron manganese or zinc for removing selenocyanate from aqueous streams. The binder may be alumina, silica, clay or metal oxide. The amount of sulfur in the bound sulfided metal may range from 5-75% by weight. In one embodiment, the bound sulfided metal is formed and reduced and placed in a column system that comprises one or more columns and may comprise a Lead-Lag1-Lag2-Polisher series of columns.
