Palladium is a rare metal element that has a wide range of applications in industry and jewelry making. In recent years, the development of palladium has been continuous, so it is very important for people in the industry to understand the purification methods of palladium.
1. How much is a gram of palladium?
The ** of palladium is affected by a variety of factors, including supply and demand, global political and economic situation, and the US dollar exchange rate. Currently, how much is a gram of palladium? Palladium** 221 yuan a gram. However, it should be noted that the ** of palladium fluctuates greatly, and the specific ** needs to be judged according to the international market situation at that time.
Second, the purification method of palladium
There are several purification methods for palladium:
1. Fire smelting.
After mixing, it is heated to high temperature to separate palladium from other impurities. After high-temperature smelting, palladium is separated from other impurities, and then refined to obtain high-purity palladium. The advantages of the pyrometallurgical smelting method are simple process and large processing capacity, but the disadvantage is high energy consumption and large environmental impact.
2. Chemical dissolution method.
Chemical dissolution is a method of dissolving palladium in solution through a chemical reaction, and then obtaining pure palladium through a reduction or displacement reaction. The advantages of the chemical dissolution method are simple operation, low energy consumption and good environmental protection, but the disadvantage is that the processing capacity is small, and it is suitable for processing a small amount of waste palladium.
3. Ion exchange method.
Ion exchange method is a method of adsorbing palladium ions in waste palladium on ion exchange resin, and then obtaining pure palladium through elution, reduction or displacement reactions. The advantages of the ion exchange method are that it is simple to operate, environmentally friendly, and has a large processing capacity, but the disadvantage is that it requires the use of a large amount of ion exchange resin, and the cost is high.
4. Bioadsorption method.
Bioadsorption is a method that uses the adsorption of palladium by microorganisms to purify palladium. The advantages of bioadsorption method are good environmental protection, large treatment capacity and good adsorption effect, but the disadvantage is that the cultivation and regeneration of microorganisms take a long time, and the requirements for waste palladium materials are high.
How much is palladium a gram? Palladium** 221 yuan a gram. How to purify palladium**? The above is an introduction to the purification method of palladium, different methods have their own advantages and disadvantages, and the appropriate method can be selected according to the actual situation for the purification of palladium. It should be noted that no matter what method is used for the purification of palladium, it is necessary to comply with relevant laws, regulations and standards to ensure safe production and environmental protection.
