[Investigation of fluorescence spectra of alum floc].
The sharp fluorescence peak of alum floc was observed at 340nm. The peak height at 340nm is in proportion to alum concentration under same degree of neutralization. There is similar regular change of this peak height as change of neutralization degree under different alum concentration.
