Rhodium refining and reusing

DEAR SIR,

How can I make GPC SALT of 68.2%2? What is the Degussa PRODUCT FOR RHODIUM solution refining and DEGUSSA AURUNA WETTING AGENT? How can I use this product?

Please search the site and you will find detailed instructions for making GPC. The two references to Degussa are apparently the names of products to be purchased from Degussa. I'm confident there is a distributor in India but that's for you to determine.
