A simple collection and separation of sulfide in bottom sediments using a small anion-exchange column followed by its spectrophotometric determination has been developed. Hydrogen sulfide, which was generated from an acidified suspension containing sulfide-bearing sediment, was collected on a small column packed with OH-type anion-exchange group (quaternary amine) bonded silica gel (OH-SP) by bubbling nitrogen gas through the solutions. The sulfide adsorbed on the OH-SP was eluted with a potassium nitrate solution, and then it was spectrophotometrically determined by the methylene blue method. The established method was successfully applied to bottom sediment samples taken from brackish Lake Nakaumi.
