This report describes the results of SuperLig® 639 sorption kinetics tests conducted at the Savannah River Technology Center (SRTC) in support of the Hanford River Protection Project - Waste Treatment Plant (RPP-WTP). The RPP-WTP contract was awarded to Bechtel for the design, construction, and initial operation of a plant for the treatment and vitrification of millions of gallons of radioactive waste currently stored in tanks at Hanford, WA. Part of the current treatment process involves the removal of technetium from tank supernate solutions using columns containing SuperLig® 639 resin. This report is part of a body of work intended to quantify and optimize the operation of the technetium removal columns with regard to various parameters (such as liquid flow rate, column aspect ratio, resin particle size, loading and elution temperature, etc.). The tests were conducted using nonradioactive simulants of the actual tank waste samples containing rhenium as a chemical surrogate for the technetium in the actual waste. Previous column tests evaluated the impacts of liquid flow rate, bed aspect ratio, solution temperature and composition upon SuperLig® 639 column performance (King et al., 2000, King et al., 2003). This report describes the results of kinetics tests to determine the impacts of resin particle size, solution composition, and temperature on the rate of uptake of perrhenate ions.
