Abstract
The total phenol content of soil samples has been measured using high performance liquid chromatography with electrochemical detection. Soil s are extracted with sodium hydroxide solution and the phenols present in the extract are recovered on solid phase C18 cartridges after pH a djustment. The measurement stage employs a short (3 cm) reversed phase column and electrochemical detection. The short column focuses the ph enolic species into a single peak which can be integrated. Electrochem ical detection provides both sensitivity and selectivity. Hence high s peed measurement of a composite peak representing total phenol content is achieved.
