A highly sensitive and selective method is described for the determination of microgram quantities of water in nonaqueous organic solvents. The method is based on the reaction of water with N, N'-carbonyldiimidazole at ambient temperature in anhydrous quinoline solvent whereby one mole of carbon dioxide gas is instantaneously and stoichiometrically liberated per mole of water. The released gas is absorbed in NaOH and monitored with a CO2 gas sensor. The method is applicable for determination of 2 pg-20 nig H2O/ml of various organic solvents. The average recovery is 99% and the mean standard deviation being 0.5%. The method displays several advantages over the standard Karl Fischer procedure. |
