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.Type: GrantFiled: September 21, 2009Date of Patent: July 30, 2013Assignee: Iofina Natural Gas, Inc.Inventors: Terry Brix, James Reynolds

Patent number: 8480889Abstract: A novel chromatographic stationary phase for reversed-phase high performance liquid chromatography (HPLC) is provided. By using mono and dimethyl silanes as endcapping reagents as compared with the use of traditional trimethyl silanes, an improved blocking of unreacted surface silanols is achieved. The improved blocking of surface silanols results in at least better peak shape and more reproducible retention times in reversed-phase HPLC analyses.Type: GrantFiled: April 27, 2006Date of Patent: July 9, 2013Assignee: Agilent Technologies, Inc.Inventor: Wu Chen
