    UOP274

    1. Scope

    This method is for determining platinum in fresh gamma-alumina, theta-alumina or silica/gamma-alumina catalysts at concentrations from approximately 0.05 to 1.0 mass-% by spectrophotometry. Catalysts containing rhenium cannot be analyzed by this method, see UOP Method 823. Any other elements that produce colored ions in the dissolution or color-development steps constitute a positive interference. These include chromium, rhodium, cobalt and molybdenum, but other elements can also interfere. When such elements are present, determine platinum by UOP Method 896.
