摘要: Spectrophotometric determination of molybdenum(VI) and tungsten(VI) with application Artificial Neural Networks is proposed it was applied for elemental analysis solid polyoxometalates. Better results in comparison previously those achieved by previous published method were demonstrated. MALDI-TOF Mass Spectrometry tested possible molecular weight polyoxometalates utilizing different matrices. Phenomena observed during desorption-ionisation processes are discussed. LDI-TOF MS found to be suitable the Mo:W ratio as a rapid screening follow synthetic procedure.
