    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, it absorbs the resonance line at 283.3 nm. Within a certain concentration range, the absorbance is proportional to the lead content. Quantitative determination is performed by comparison with a standard […]<\/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-3995","post","type-post","status-publish","format-standard","hentry","category-applications","category-food-and-drugs"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.pgeneral.com\/ko\/wp-json\/wp\/v2\/posts\/3995","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.pgeneral.com\/ko\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.pgeneral.com\/ko\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.pgeneral.com\/ko\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.pgeneral.com\/ko\/wp-json\/wp\/v2\/comments?post=3995"}],"version-history":[{"count":0,"href":"https:\/\/www.pgeneral.com\/ko\/wp-json\/wp\/v2\/posts\/3995\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.pgeneral.com\/ko\/wp-json\/wp\/v2\/media?parent=3995"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.pgeneral.com\/ko\/wp-json\/wp\/v2\/categories?post=3995"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.pgeneral.com\/ko\/wp-json\/wp\/v2\/tags?post=3995"}],"curies":[{"name":"WP","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
