   Information on the recovery of platinum and rhodium wire from a pawn shop, introduces the method of recycling rhodium waste, the same method, that is, the use of ruthenium after distillation and fractionation, the use of solvents and other methods. In the extraction process of purifying rhodium, formic acid reduction is carried out and combustion is carried out until rhodium is obtained. The table provides the analysis results of rhodium. Rhodium recovers few impurities, and the grade exceeds the quality. The price of platinum and rhodium thermocouples is now recovered. The composition table is the quality of rhodium recovered from rhodium processing waste. The following describes a comparative example of the recovery of palladium, platinum and rhodium. The comparative example was crushed and directly mixed with carbon powder, and chlorinated using the same method as the example, except that the rhodium shown in the table of the example was not treated as garbage. Here the particle size is the state of the particles. Millimeters and millimeters left and right, the rhodium treatment before pulverization is the rinsing residue obtained after the platinum is contained in the pure water using a vacuum filter and the washing agent is added, and the regeneration agent is washed on the filter paper and dried on the filter paper at room temperature. The composition and content distribution ratio of the lotion are provided in the table, and the rinsing residue composition and content distribution ratio are provided in the platinum and rhodium waste price list. Platinum and copper are dissolved in the water washing liquid, but the distribution ratio is very low. In the rinse residue, the remaining palladium and platinum cannot be sufficiently separated from the rhodium.

 
   X-ray diffraction measurements have been carried out, and the results show that palladium and platinum are in the form of metals, indicating that the chlorination reaction will not advance to the inside of the particles due to the larger particles. Taiwan's washing liquid is chlorinated. Catalytic converter platinum waste price comparison example. The rhodium shown in the table is used to treat the waste and pulverize the rice in the powder sample that passes through the sieve in the mesh. The powdered carbon is not mixed, and the same method as the example is used for chlorination. deal with. The treated material is washed with pure water at room temperature, the waste palladium is filtered with a vacuum filter, and the rhodium is now recovered by sodium borohydride. A lotion containing platinum and palladium is obtained. In addition, after the regenerant on the filter paper is dried, a rinse residue is obtained. The rhodium price list provides the composition and content distribution ratio of the lotion, and the table provides the composition and content distribution ratio of the rinse residue. Palladium, platinum and copper are dissolved in the water washing solution, but the distribution ratio is very low. The remaining palladium and platinum cannot be sufficiently separated from the rhodium in the rinsing residue, respectively. X-ray diffraction measurement was performed. As a result, oxides of palladium and platinum were detected, and the chlorination reaction did not proceed due to the presence of a surface oxide layer. The composition and content of water per gram of rhodium waste price list chlorinated things. The comparative example is based on the temperature of the processed chlorinated waste except for the rhodium shown in the table, using the same method as the processing in the example, washing purified water at room temperature and filtering with a vacuum filter to obtain platinum and palladium In addition, the regenerant on the filter paper is dried to obtain the rinsing residue. The composition and content distribution ratio are provided in the table. In addition, the composition of the rinse residue is provided in the table. Although the palladium and platinum are dissolved in the lotion, where can rhodium be found, the distribution ratio is very low in the form of the rinse residue. Respectively and in the rinse residue, the remaining palladium and platinum cannot be sufficiently separated from the rhodium.


 
   The form of the rinsing residue has been determined by X-ray diffraction. The result is that the form of palladium and platinum is metal, indicating that the chlorination reaction will not proceed due to the low chlorination temperature. In the comparative example, chlorination was performed in the same manner as in the example except that the rhodium shown in the table was processed to the maintenance temperature of the garbage chloride. The treated material was washed with pure water at room temperature and filtered with a vacuum filter. How much rhodium in the catalytic converter gets the water washing agent containing platinum and palladium. In addition, the reclaiming agent on the filter paper is dried to obtain the rinsing residue. The composition of the lotion is provided in the table, and the content distribution ratio is provided in the table. The composition of the lotion is provided. The content distribution ratio of palladium and platinum are respectively dissolved in the lotion, and the distribution ratios are respectively and, in the rinse residue, palladium and platinum Rarely below, it can be completely separated with rhodium. It is basically insoluble in water, and the distribution rate in the rinsing residue is low. This is because the chlorination temperature is high, the rhodium chloride in the chloride sublimates, and the recovery rate reduces the composition and content of the water. The recovery of palladium, platinum and rhodium involves a method for recovering and purifying platinum and rhodium from waste materials containing platinum and rhodium, at the latest recovery price of rhodium powder. It belongs to the technical field of chemical extraction of precious metal palladium, platinum and rhodium. This palladium, platinum and rhodium recovery uses an ion exchange method to remove base metals, and combines
