Abstract

Studies were undertaken on the isolation and identification of reaction products of triammonium pyrophosphate (TPP), the major non-orthophosphate constituent of ammonium polyphosphate newly introduced in India, in representative soils of the alfisol, oxisol, entisol, mollisol and vertisol groups of India. Saturated solution of TPP were reacted with soils for periods of 30 minutes and one day with corresponding precipitation times of 15 days, three months and one year to isolate reaction products which were identified by X-ray diffraction technique, infra-red spectroscopy and chemical analyses. Six reaction products, namely, Ca(NH4)2P2O7 . H2O, Mg(NH4)2P2O7 . 4H2O, Ca(NH4)4H2(P2O7)2, Ca3(NH4)4H6(P2O7)4.3H2O, FeNH4P2O7 and NH4Al0.33 Fe0.67P2O...
