860 SULFATE - SULFUR IN WATER
SO4S
Amount of sulfate-sulfur present in H2O by ICP-AES.
Summary: Method quantitatively measures the concentration of soluble sulfur in the water sample. The result is based on the determination of soluble sulfur using an Inductively Coupled Plasma Atomic Emission Spectrometer (ICP-AES) and assumes that all sulfur present is in the sulfate form. The ICP-AES method has a detection limit of 0.1 mg/L. The analysis requires approximately 5 mL of sample but 15 mL is requested to allow for quality control samples. If sulfate is of specific interest, the ion chromatographic method should be requested.
