  • Laboratory experiments have been performed on the sorption of radionuclides on tuff as site characterization information for the Yucca Mountain Project. This paper presents general observations on the results of curve-fitting of sorption data by a Modified Langmuir isotherm equation and the effects of experimental variables on their regressional analysis. Observations are specific to problems associated with fitting the isotherm, the calculation of isotherm parameters, and the significance of experimental variables such as replication and particle size. These observations are important in the design of laboratory experiments to ensure that collected data are adequate for effectively characterizing sorption of radionuclides on tuffs or other materials. © 1991, Walter de Gruyter.
