Pressure Dependence of Carbonate Exchange with NpO2(CO3)3(4-) in Aqueous Solutions.

07:00 EST 13th December 2016 | BioPortfolio

Summary of "Pressure Dependence of Carbonate Exchange with NpO2(CO3)3(4-) in Aqueous Solutions."

The rates of ligand exchange into the geochemically important [NpO2(CO3)3](4-) aqueous complex are measured as a function of pressure in order to complement existing data on the isostructural [UO2(CO3)3](4-) complex. Experiments are conducted at pH conditions where the rate of exchange is independent of the proton concentration. Unexpectedly, the experiments show a distinct difference in the pressure dependencies of rates of exchange for the uranyl and neptunyl complexes.

Medical and Biotech [MESH] Definitions

Solutions prepared for hemodialysis. The composition of the pre-dialysis solution may be varied in order to determine the effect of solvated metabolites on anoxia, malnutrition, acid-base balance, etc. Of principal interest are the effect of the choice of buffers (e.g., acetate or carbonate), the addition of cations (Na+, K+, Ca2+), and addition of carbohydrates (glucose).

Solutions prepared for exchange across a semipermeable membrane of solutes below a molecular size determined by the cutoff threshold of the membrane material.

Solutions that have a greater osmotic pressure than a reference solution such as blood, plasma, or interstitial fluid.

Solutions that have a lesser osmotic pressure than a reference solution such as blood, plasma, or interstitial fluid.

Separation technique in which the stationary phase consists of ion exchange resins. The resins contain loosely held small ions that easily exchange places with other small ions of like charge present in solutions washed over the resins.
