A new method for simultaneous determination of ammonium and potassium involving precipitation and thermal decomposition of K[B(C6H5)4] and NH4[B(C6H5)4has been presented. Decomposition of tetraphenylborates has been carried out using a derivato-graph and a ihermoanalyser coupled with a mass spectrometer. Gaseous products of decomposition have been identified. Determination procedure of potassium and...
The work presents a new method of simultaneous determination of ammonium and potassium, involving precipitation and thermal decomposition of K2Na[Co(NO2)6]źH2O and (NH4)2Na[Co(NO2)6]źH2O. Using a thermoanalyser coupled with a mass spectrometer, one investigated thermal decomposition of nitritocobaltates(III) in the argon atmosphere and identified the obtained gaseous products. Decomposition of ammonium-sodium...
