Search for an IR camera continued. Several manufactures have been contacted for specifications and pricing. Research on current market available sensor that within allocated budget continued. Jang, PI Saltcake dissolution. The differences were observed primarily in the 1m OH solutions at the lower temperature.
Further investigation is in progress.
The revised data set will allow additional comparisons to previous calculations involving this important system. The initial solution concentrations were based on the ESP calculations and it seems likely that the ESP model is over-predicting solubilities. Ionic concentrations compared favorably to literature data at high sulfate concentrations but deviated at intermediate and higher carbonate concentrations. Predictions were made using the ESP Public database alone and with combinations of the Trona and Na2Snacl database. Results from the Trona and public database combination and the public database alone indicated a large gap where no solids were observed - in direct disagreement with experimental results found in the literature.
