Screen-printed potentiometric sensors have been developed to detect the presence of chloride ions within moist soils. In work previously published by some of the authors, sensor lifetimes in excess of 1 year have been established with near Nernstian response to chloride ions (-49.8 ± 1.7 mV per decade) over the range 0.1 mM (3.55 mg/L) to 200 mM (7.09 g/L). The sensors demonstrate the ability to measure transient changes in soil chloride concentration allowing chloride retention times in different types of soil to be determined. © 2012 The Authors.
