The method includes the determination of particulate organic carbon using combined ultrasonic and alkaline extraction (CUAL) pretreatment and quantification by the difference between total carbon (TC) and total inorganic carbon (TIC).
Typical matrices include wastewater, stormwater, leachates, and surface water.
