分離和提純常用的化學(xué)方法 </p> <p> 1.加熱法： </p> <p> 當(dāng)混合物中混有熱穩(wěn)定性差的物質(zhì)時(shí)，可直接加熱，使熱穩(wěn)定性差的物質(zhì)分解而分離出去。如，NaCl中混有NH4Cl，重慶除砷絮凝劑公司，Na2CO3中混有NaHCO3等均可直接加熱除去雜質(zhì)。 </p> <p> 2.沉淀法： </p> <p> 在混合物中加入某種試劑，使其中一種以沉淀的形式分離出去的方法。使用該方法一定要注意不能引入新的雜質(zhì)。若使用多種試劑將溶液中不同微粒逐步沉淀時(shí)，應(yīng)注意后加試劑的過(guò)量部分除去，加的試劑不引入新的雜質(zhì)。如，加適量的BaCl2溶液可除去NaCl中混有的Na2SO4。 </p> <p> 3.酸堿法： </p> <p> 被提純的物質(zhì)不與酸堿反應(yīng)，而雜質(zhì)可與酸堿反應(yīng)，用酸堿作除雜試劑。如用鹽酸除去SiO2中的CaCO3，用氫氧化鈉溶液除去鐵粉中的鋁粉等。 </p> <p> <br />

style="text-indent:25px">砷是一種對(duì)人體危害極大的污染物,在自然水體中主要以三價(jià)的亞砷酸鹽和五價(jià)的砷酸鹽兩種形態(tài)存在。在去除砷的眾多方法中,納米零價(jià)鐵去除是一種比較常用的方法,這主要由于納米零價(jià)鐵具有高比表面積、高活性等特點(diǎn)。但是,納米零價(jià)鐵尺寸小、活性高,難以保存,很難用常規(guī)方法回收,從而造成二次污染。在眾多除砷方法中，吸附法以方便、安全、不產(chǎn)生二次污染、不添加大量化學(xué)試劑被普遍應(yīng)用，因此制備價(jià)格低廉，吸附再生效果好，能應(yīng)用于實(shí)際含砷廢水處理的吸附材料尤為重要。一般的納米金屬材料極易溶于水，不易于二次分離和重復(fù)再利用，因此通過(guò)負(fù)載合適的載體來(lái)改善此問(wèn)題。</p><p
