Hello friends , I have aproblem with precipitating pt and pd from an aqua regia solution that I made from an ore near by ,
It is giving a colored indication of stannus chloride test so I didn't found any precipitation of au with sadium metabisupfite , so I tested with pt and pd precipitation . I did adding aluminium foil . So I ve got a brownish color powder precipitation ,
Can any one please guide me on this situation .
Thank you and good day
Interesting challenge! It seems like you’re dealing with a complex solution. The brownish powder could indicate mixed metal precipitates. Have you tried adjusting the pH of the solution or using ammonium chloride for selective precipitation of platinum and palladium? These steps might help refine your process.

To precipitate platinum (Pt) and palladium (Pd) from an aqua regia solution, first dilute the solution with water to reduce its acidity. Then, add a reducing agent such as sodium chloride (NaCl) or ammonium chloride (NH4Cl). This will cause platinum and palladium to form insoluble chloride complexes, which can be filtered out. After filtering, wash the precipitate with distilled water to remove impurities. Finally, dry the precipitate and perform any further processing, like heating, to obtain pure metals.

To precipitate platinum (Pt) and palladium (Pd) from an aqua regia solution, you can use a reducing agent like ammonium chloride or sodium chloride. First, dilute the aqua regia solution and heat it to dissolve the metals. Then, add the chloride solution gradually to the mixture. Palladium will typically precipitate as palladium chloride (PdCl2), while platinum may remain dissolved, requiring further treatment. For platinum, you may need to add a stronger reducing agent, such as hydrogen gas, to precipitate it as platinum black. Always handle aqua regia with caution.

To precipitate platinum (Pt) and palladium (Pd) from an aqua regia solution, the process typically involves reducing these metals from their dissolved state. Aqua regia, a mixture of hydrochloric and nitric acids, dissolves platinum and palladium, forming chloride complexes. To precipitate Pt and Pd, a reducing agent like ammonium chloride or ferrous sulfate is added. This reduction causes the metals to separate from the solution as solid particles, which can then be filtered out.

To precipitate platinum (Pt) and palladium (Pd) from an aqua regia solution, a common method involves adding a reducing agent like sodium chloride (NaCl) or ammonium chloride (NH4Cl) to the solution. This causes the platinum and palladium to form insoluble chlorides, which can then be separated by filtration. The precipitate is usually in the form of platinum or palladium chloride, and further steps can be taken to recover the pure metals. While performing such processes, it's important to stay connected for research updates and queries. GB WhatsApp APK can be a great tool to communicate with colleagues and share information.
