Organo phosphorus compounds are decomposed by closed-flask combustion. The phosphate ions produced are then converted to phosphomolybdic acid and extracted withiso- butyl acetate. The 12molybdate ions associated with each original phosphate ion are s

The closed-flask combustion products of some nitrogen compounds were studied. The percentage of nitrogen oxides formed (expressed as nitrate-nitrogen) was determined. Combustion of these samples, after mixing with inorganic oxidants, in a stream of o
