摘要：

Raman spectroscopy is used to monitor hydrolysis of a polyphosphate dissolved in water at pH = 0. It is found that this reaction is of zeroth-order and obeys the Arrhenius equation with E-a = 57 kJ.mole(-1). Hydrolysis predominantly takes place at terminal phosphate units, and, although random hydrolysis might be involved in the process, its contribution is shown to be very small with respect to the overall process.
