Description
A novel method that combines FT-IR and bulk carbon XAS spectroscopy results using a linear mass balance model constrained by elemental analysis to quantify the abundance of seven SOC functional groups. Uses the Beer-Lambert Law where total organic carbon constrains the sum of functional groups from both techniques.
