PURPOSE:To efficiently and inexpensively obtain mercury oxide surely separated from mercury and water by separating the mercury oxide obtained by anodizing metallic mercury and water with a double-cone distillation separator. CONSTITUTION:Since the electrolytic mercury oxide contains a large amt. of metallic mercury, the sample separated by centrifugal separation is charged into the main body of a double cone 1 from an upper feed port 7. As the main body of the double cone 1 is evacuated by a water-jet vacuum pump 4, the moisture evaporated by heating is collected by the water-jet pump. The temp. is initially set at 100 deg.C to prevent the condensation of water in the cyclone 2, condenser 3 and cold trap 5. When water has been distilled and separated, the heating temp. is increased to 220 deg.C, and mercury is distilled. The mercury evaporated by heating is collected in the condenser 3, and the mercury not trapped in the condenser 3 is collected by the cold trap 5. |
