style="text-indent:25px">一異丙醇胺(MIPA)及其衍生物在化學(xué)分析中有多種用途，普遍用作金屬離子的萃取劑、沉淀劑及熒光分析試劑。由于一異丙醇胺(MIPA)能與金屬離子形成難溶于水的配合物,這些沉淀物經(jīng)干燥后，可以直接稱量(重量法)，也可以通過用溴量法測(cè)定一異丙醇胺(MIPA)鹽(滴定法),還可以用三氯甲烷或苯來萃取一異丙醇胺(MIPA)鹽后再用分光光度法(萃取-分光光度法)來測(cè)定金屬離子含量。通過控制反應(yīng)的條件,或選擇特殊結(jié)構(gòu)的一異丙醇胺(MIPA)衍生物作為分析試劑，可以提高反應(yīng)的選擇性和金屬離子檢測(cè)的靈敏度。長(zhǎng)期以來有關(guān)此領(lǐng)域的研究備受人們的關(guān)注。</p><p style="text-indent:25px">一異丙醇胺(MIPA)貯存：一異丙醇胺(MIPA)在化學(xué)制品檢驗(yàn)中具有十分重要的地位。隨著儀器分析的普遍使用，必將越來越多地使用化學(xué)制品標(biāo)準(zhǔn)物質(zhì)。只有嚴(yán)格按照化學(xué)一異丙醇胺(MIPA)說明書要求使用和貯存一異丙醇胺(MIPA)，才可以提高化學(xué)制品檢驗(yàn)結(jié)果的準(zhǔn)確性。一異丙醇胺(MIPA)應(yīng)按說明書規(guī)定的條件妥善保存，一般置干燥陰涼處保存，某些一異丙醇胺(MIPA)如維生素E等需避光低溫保存。要注意一異丙醇胺(MIPA)的使用期限，過期、變質(zhì)的一異丙醇胺(MIPA)不宜再使用。開瓶后建議短期內(nèi)用完，避免開瓶后長(zhǎng)期不用，同時(shí)，在重復(fù)使用過程中應(yīng)盡量避免一異丙醇胺(MIPA)的分解、污染或吸潮。一異丙醇胺(MIPA)作為一種特殊的物質(zhì)，需要有特殊的保存方式。</p><div
