ASTM UOP303-07<\/h3>\n

Historical Standard: Impurities in Catalysts by ICP-OES<\/h4>\n
\n

ASTM UOP303<\/h4>\n

Scope<\/strong><\/p>\n

This method is for determining trace metal elements in fresh, regenerated and spent alumina-, silica- or silica\/alumina-based catalysts by Inductively Coupled Plasma-Atomic Emission Spectroscopy (ICP-AES). Fe, Ni, V, Ca, Mg, Mn, Cr, Sn, Cu, Zn, Ti, Pb, Na, Mo, Co and Si are determined quantitatively on catalysts. Si is not determined when it is a component of the catalyst base. Other elements can be added if required, however, Ba and Hg cannot be determined. In addition, As and P are determined on regenerated or spent alumina-based catalyst. The majority of the specified elements can be determined within the concentration range of 0.005 to 2.0 mass-%. Specific concentration ranges for the elements determined are listed in Table 1.<\/p>\n

This method is not applicable to noble metals and modifiers on catalysts. Those elements can be determined by UOP Method 873.<\/p>\n

This method cannot be used for determining impurities in alpha-alumina catalyst.<\/p>\n
