In order to get basic information
For both drugs, the ammonium and nitrate ions were identified; their total concentration was higher for IF compare to CF, but it still remained lower than the maximum concentration. The release of PO43− ions indicates the decomposition of heteroatoms ring in the drugs molecules ( Fig. 5). Therefore it can be assumed that the destruction of IF heteroatoms ring was more advanced and the lower amount of organic intermediates containing the phosphorus and nitrogen atoms (organic nitrogen, Norg) was present in the solution.
