Systems and methods for the recovery of iodine are described. In particular, recovery systems and methods produce an iodine complex from an aqueous brine containing iodide. A head tank for maintains a supply of the brine, a pH controller acidifies brine received from the head tank and an oxidizer converts iodide in the acidified brine to elemental iodine. At least one activated carbon contactor module is removably inserted into a stream of the oxidized brine provided by the oxidizer and binds the molecular iodine to form the iodine complex. A container may enclose the head tank, the pH controller and the oxidizer in order to facilitate transportation of the system and performance of the methods and processes in proximity to a brine source. The brine may be employed or associated with oilfield operations.
