| General tips | For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months. We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months. Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it. |

PVC membrane based potentiometric sensors for uranium determination.[Pubmed:18968336]
Talanta. 2001 Jul 6;54(6):1153-61.
Two novel uranyl PVC matrix membrane sensors responsive to uranyl ion are described. The first sensor incorporates tris(2-ethylhexyl)phosphate (TEHP) as both electroactive material and plasticizer and sodium tetraphenylborate (NaTPB) as an ion discriminator. The sensor displays a rapid and linear response for UO(2)(2+) ions over the concentration range 1x10(-1)-2x10(-5) mol l(-1) UO(2)(2+) with a cationic slope of 25.0+/-0.2 mV decade(-1). The working pH range is 2.8-3.6 and the life span is 4 weeks. The second sensor contains O-(1,2-dihydro-2-oxo-1-pyridyl)-N,N,N',N'-bis(tetra-methylene)uronium hexafluorophosphate (TPTU) as a sensing material, sodium tetraphenylborate as an ion discriminator and dioctyl phenylphosphonate (DOPP) as a plasticizer. Linear and stable response for 1x10(-1)-5x10(-5) mol l(-1) UO(2)(2+) with near-Nernstian slope of 27.5+/-0.2 mV decade(-1) are obtained. The working pH range is 2.5-3.5 and the life span of the sensor is 6 weeks. Interference from many inorganic cations is negligible for both sensors. However, interference caused by some ions (e.g. Th(4+), Cu(2+), Fe(3+)) is eliminated by a prior ion exchange or solvent extraction step. Direct potentiometric determination of as little as 5 mug ml(-1) uranium in aqueous solutions shows an average recovery of 97.2+/-1.3%. Application for the determination of uranium at levels of 0.01-1 wt.% in naturally occurring and certified ores gives results with good correlation with data obtained by X-ray fluorescence.
