Potentiometric multi-syringe flow injection system for determination of exchangeable potassium in soils with in-line extraction
A multi-syringe flow injection system for the potentiometric determination of exchangeable potassium in soil samples is proposed. Firstly, a manifold was devised to allow determination in soil extracts prepared off-line. It was possible to analyze samples prepared in extractants with different compo...
