Abstract:
1. A portable system for on-site iodine extraction, comprising: a mobile platform; a treatment unit capable of oxidizing iodine ions in a solution into elemental iodine; and an adsorption unit capable of adsorbing iodine; wherein the treatment unit includes an in-line mixing apparatus comprising: an outer tube comprising a sidewall, a closed end, an open end opposite the closed end, a first opening in the open end, and a second opening in the sidewall adjacent the open end; an inner tube comprising an inlet end, a closed end, and a sidewall, the sidewall having openings therein, the inner tube being located coaxially inside the outer tube and having a cross-sectional area, and the inlet end of the inner tube being adjacent to the open end of the outer tube; wherein the outer tube closed end is adjacent to the inner tube closed end, the outer tube closed end and the inner tube closed end being separated by a longitudinal gap so that the inner tube closed end does not contact the outer tube closed end, and an annular volume is defined between the outer tube and the inner tube; a first feed tube connected to the inlet end of the inner tube and passing through the second opening; and an exit tube connected to the first opening in the open end of the outer tube; wherein fluid flowing from the first feed tube to the exit tube undergoes a counter-current change in flow within the annular volume.
