          Method Overview After the sample is dissolved in 2% nitric acid, it is injected into the graphite furnace of an atomic absorption spectrophotometer. After electrothermal atomization, it absorbs the resonance line at 247.6nm. Within a certain concentration range, the absorbance is proportional to the palladium content, and quantification is performed by comparison with the standard […]<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[36,77],"tags":[],"class_list":["post-4559","post","type-post","status-publish","format-standard","hentry","category-applications","category-bio-tech-and-life-sciences"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.pgeneral.com\/fr\/wp-json\/wp\/v2\/posts\/4559","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.pgeneral.com\/fr\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.pgeneral.com\/fr\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.pgeneral.com\/fr\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.pgeneral.com\/fr\/wp-json\/wp\/v2\/comments?post=4559"}],"version-history":[{"count":1,"href":"https:\/\/www.pgeneral.com\/fr\/wp-json\/wp\/v2\/posts\/4559\/revisions"}],"predecessor-version":[{"id":4560,"href":"https:\/\/www.pgeneral.com\/fr\/wp-json\/wp\/v2\/posts\/4559\/revisions\/4560"}],"wp:attachment":[{"href":"https:\/\/www.pgeneral.com\/fr\/wp-json\/wp\/v2\/media?parent=4559"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.pgeneral.com\/fr\/wp-json\/wp\/v2\/categories?post=4559"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.pgeneral.com\/fr\/wp-json\/wp\/v2\/tags?post=4559"}],"curies":[{"name":"WP","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
