style="text-indent:25px">原子吸收分光光度計(jì)中常用的定量辦法：規(guī)范曲線法。規(guī)范曲線法是用規(guī)范物質(zhì)制造一系列已知濃度的規(guī)范試樣，在規(guī)范條件下，測得每一濃度對應(yīng)的吸光度值，以吸光度對濃度作圖，制作規(guī)范曲線。在相同條件下測定樣品吸光度，從規(guī)范曲線上讀取樣品濃度。長處：適用范圍廣，快速簡便，合適大批量樣品的測定。缺乏：試驗(yàn)準(zhǔn)確度受基體干擾嚴(yán)重。規(guī)范參加法：規(guī)范參加法是在數(shù)個(gè)等分的試樣平分別參加呈比例的規(guī)范試樣，然后稀釋到一定體積。根據(jù)測定的吸光度值，制作吸光度A-c（濃度）曲線。用外推法求得稀釋后試樣中待測物的濃度。元素原子吸收分光光度計(jì)差價(jià)原子吸收分光光度計(jì)應(yīng)用不普遍。</p><div
