          1. Method Overview After the sample is digested by microwave, it is injected into the graphite furnace of an atomic absorption spectrophotometer. After electrothermal atomization, the sample absorbs the resonance line at 283.3 nm. Within a certain concentration range, the absorbance value is proportional to the lead content, and quantification is performed by comparison with […]<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[36,73],"tags":[],"class_list":["post-3899","post","type-post","status-publish","format-standard","hentry","category-applications","category-food-and-drugs"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.pgeneral.com\/vi\/wp-json\/wp\/v2\/posts\/3899","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.pgeneral.com\/vi\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.pgeneral.com\/vi\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.pgeneral.com\/vi\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.pgeneral.com\/vi\/wp-json\/wp\/v2\/comments?post=3899"}],"version-history":[{"count":0,"href":"https:\/\/www.pgeneral.com\/vi\/wp-json\/wp\/v2\/posts\/3899\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.pgeneral.com\/vi\/wp-json\/wp\/v2\/media?parent=3899"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.pgeneral.com\/vi\/wp-json\/wp\/v2\/categories?post=3899"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.pgeneral.com\/vi\/wp-json\/wp\/v2\/tags?post=3899"}],"curies":[{"name":"WP","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
