A lead-loaded chelating resin (PbR) column is proposed for a simple field determination of dissolved sulfide (total of H2S, HS-, S2-) in environmental water samples. The PbR was prepared as follows. A chelating resin (100200 mesh, Bio Rad Chelex 100 chelating ion-exchange resin, 50 g) was mixed with 500 ml of a 0.001 M lead nitrate solution for 2 hours, filtered off, and mixed with 500 ml of artificial seawater for 10 min. A 0.7 ml (0.15 g) portion of the thus-prepared PbR was put into a glass column of 4.0 mmφ×80 mm (length of PbR layer, 55 mm). Ten milliliters of a water sample were taken into a graduated syringe and 0.5 ml of a buffer solution (pH 6.8) added. For the determination, after the solution in the syringe was passed through the PbR column at a flow rate of 4 ml min-1 the length of a black-colored layer appearing in the column was measured. The length of the colored layer was proportional to the concentration of dissolved sulfide in the water. Up to 200 μg sulfide-S can be determined with a relative standard deviation of 4.0% (n=10). The PbR column method is applicable to field determinations of dissolved sulfide in seawater and brackish water as well as fresh water.
