</p> <p> <br /> </p><p> <span style="font-size:16px;">光譜分析法的基本原理，眾所周知，物質(zhì)是由原子構(gòu)成的。原子的主要結(jié)構(gòu)包括位于**的原子核和其外時(shí)刻在運(yùn)動(dòng)著的核外電子兩部分。由能量比較低原理，通常情況下原子處于能量都比較低的穩(wěn)定狀態(tài)，也稱(chēng)其為基態(tài)。但當(dāng)原子受到外界能量( 如熱能、電能等) 的作用時(shí)，原子由于與高速運(yùn)動(dòng)的氣態(tài)粒子和電子相互碰撞而獲得了能量，使原子中外層的電子從基態(tài)躍遷到更高的能級(jí)上，處在這種狀態(tài)的原子稱(chēng)激發(fā)態(tài)。如果原子中的核外電子由基態(tài)到激發(fā)態(tài)躍遷所需的能量是由光能提供的，且提供的能量數(shù)值上與某一能級(jí)能量與比較低能基態(tài)的差相等時(shí)，原子就可以恰好將提供能量的光吸收。這樣原來(lái)提供能量的光經(jīng)</span><span style="font-size:16px;">分光后譜線中便缺少了一些特征光譜線，從而產(chǎn)生原子吸收光譜。吸收光譜原理是對(duì)樣品進(jìn)行檢測(cè)時(shí) 先讓其變成蒸汽，明確要對(duì)哪種元素進(jìn)行檢測(cè)后進(jìn) 行操作，使蒸汽吸收預(yù)檢測(cè)元素的特征光譜，通過(guò)剩下的強(qiáng)度計(jì)算被吸收的量，從而確定元素含量。</span> </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"
