I mean to say the relationship between FT-IR, GC-MS and Calorific value of the lignin

A. Oluwafemi Oluwadare

The purity level of the ppted lignin will determine its value. I will recommend that you start thinking about platicistization of lignin and other value addded products that are bio-based.

Thank you Prof. for the response.
