WebFourier-transform infrared spectroscopy (FTIR) results show that both bidentate (≡Fe 2 PO 4) and monodentate (≡FePO 4) complexes are formed during phosphate adsorption on HFO surface. Quantitative relationships between phosphate adsorption and salinity are proposed for the different pHs investigated in this study, which is important for the ... WebKeywords: composite, fiberglass, phosphate, AlPO4; FTIR. INTRODUCTION Flame retardants are chemical materials used to diminish the spread or intensity of fire. The function of this fire retardant is to decrease the potential of ignition and delay the spread of flame. Polyester resin contributes to give effect on the combustibility of the underlying
