Abstract

1283389 Recovery of platinum group metal salts ATLANTIC RICHFIELD CO 22 Oct 1969 51860/69 Heading C1A Platinum group metal (Ru, Rh, Pd, Os, Ir and Pt) double salts are recovered from contaminated platinum group metal catalysts by dissolving the metal in a solution containing an oxidant which supplies peroxidic oxygen, an acid supplying an anion, and a cation, at up to 100‹ C., separating any undissolved solids and precipitating the double salt by cooling. Starting material may include silica, which is insoluble in the recovery solution. Specified oxidants are H 2 O 2 , persulphates, organic peroxides and hydroperoxides; specified acids are HCl, HBr, H 2 SO 4 , HNO 3 , H 3 PO 4 , HClO 3 , HClO 4 and fluoboric acids and acetic, mono- and trichloracetic acids; specified salts are nitrates, sulphates and halides of Li, Na, K, Rb and Cs; and specified solvents are water and acetic acid. After the first crystallization and separation of the double salt, the solution may be evaporated and another crop obtained. The crystals may be washed with aqueous acetone, methanol, ethanol, dioxane, tetrahydrofurane t-butyl alcohol, dimethyl formamide or dimethyl sulphoxide. Specified double salts which may be formed are lithium or potassium palladous chloride, sodium palladous iodide, lithium platinum chloride and nitrate and potassium platinum chlorate or fluoborate.
