All these elements except silicon can also be determined in fresh silica-alumina supported catalysts. The method is sufficiently flexible to permit the determination of other metals at trace levels if they can be brought into solution using the sample preparation procedure described. Concentration ranges covered are listed in Table 1. Catalysts containing alpha- or theta-alumina phases cannot be analyzed by this method.<\/p>\n<p><strong>Keywords<\/strong><\/p>\n<p><strong>ICS Code<\/strong><\/p>\n<p>ICS Number Code<\/p>\n<p><strong>DOI:<\/strong><\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p><b>UOP927-92 Trace Metallic Impurities in Fresh Catalysts by ICP-AES<\/b><\/p>\n<table class=\"shortdes-table\" style=\"width: 100%\" border=\"0\" cellspacing=\"0\" cellpadding=\"0\">\n<tbody>\n<tr>\n<td>Published By<\/td>\n<td>Publication Date<\/td>\n<td>Number of Pages<\/td>\n<\/tr>\n<tr>\n<td><a href=\"https:\/\/pdfstandards.shop\/product-category\/publishers\/astm\/\"><b>ASTM<\/b><\/a><\/td>\n<td>1992<\/td>\n<td>7<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"featured_media":299946,"template":"","meta":{"rank_math_lock_modified_date":false,"ep_exclude_from_search":false},"product_cat":[2637],"product_tag":[],"class_list":{"0":"post-299941","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-astm","8":"first","9":"instock","10":"sold-individually","11":"shipping-taxable","12":"purchasable","13":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product\/299941","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media\/299946"}],"wp:attachment":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media?parent=299941"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_cat?post=299941"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_tag?post=299941"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
