Abstract:

The objective of this work was development of a procedure for assessing the chemical properties of flocculant polymers as delivered. The method chosen was FTIR (Fourier Transform InfraRed spectroscopy) which provides a spectrum to serve as a “fingerprint” for the product. A protocol for use of the FTIR spectrometer was developed, including a library of spectra for common formulations. Spectra for unknown or delivered products can then be compared to the library of archived spectra. Different polymer chemistries can easily be distinguished including varying charge content and the effects of degradation by hydrolysis. A statistical method allows use of pre-specified similarity ranges for product acceptance or rejection.
