A Method for Detecting and Estimating Hydrogen Sulfide in Flooded Soil¹

ABSTRACT

A 60-ml sorption cell utilizing 0.5 mil PVC membranes permeable to H₂S is described. NaOH is used as the sorbing solution. The cell is capable of detecting H₂S in soil zones containing < 0.1 ppm in groundwater over short and prolonged periods of anaerobic flooding under conditions of a fluctuating water table.
