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
To precipitate platinum (Pt) and palladium (Pd) from an aqua regia solution, reducing agents like ammonium chloride or sodium borohydride are often used. These agents help convert dissolved metals into their solid form, allowing them to be filtered and recovered.
