| 内容記述 | [Abstract]The sulfur isotope ratio in mercuric sulfide called vermilion has been measured for identification of the original mines of vermilion used in ancient burial mounds and antiquities. Barium sulfate is prepared from vermilion for measurement of the sulfur isotope ratio. However, as vermilion is composed of sulfur and mercury, one issue is the prevention of contamination of barium sulfate by mercury. Mercury is a toxic metal and pollutes the piping system of analytical instruments. The aim of the present study was to establish a method of sulfur isotope analysis sampling that does not includemercury. Mercuric sulfide was dissolved in reverse aqua regia. and sulfur ion was oxidized to sulfate ion with the addition of bromine. When we observed whether mercury was adsorbed by either cation- or anion-exchange resins, mercury completely adhered to neither resin. Barium chloride was then added to the solution without using an ion-exchange resin. No mercury was detected in the precipitate of barium sulfate, and the recovery ratio wasover 90 % when the ratios of water for the reverse aqua regia before adding barium chloride were more than double. We concluded that this method for precipitating of barium sulfate by the addition of barium chloride is simple and useful for removing mercury. | |||||||||||||||||
