SYNOPSIS
This paper provides the theoretic background for the measurement of TPH using MIR with RemScan.
- The potential as a rapid and accurate non-destructive method to determine TPH concentrations is proposed.
- The most sensitive parts of the IR spectra were investigated and identified.
- Provides background for selection of MIR DRIFT technique.
- Spectra are provided for a range of concentrations of TPH in a range of different soil types.
- PLS modelling confirms the viability of accurate TPH measurements in soil with little interferences from Soil Organic Matter (SOM) or carbonate.
