style="text-indent:25px">實(shí)驗(yàn)室超純水的質(zhì)量要求：外觀與等級(jí)；實(shí)驗(yàn)室超純水應(yīng)為無色透明的液體，其中不得有肉眼可辨的顏色及纖絮雜質(zhì)。通常將實(shí)驗(yàn)室超純水分三個(gè)等級(jí)。① 一級(jí)水；不含有溶解雜質(zhì)或膠態(tài)質(zhì)有機(jī)物，用于制備標(biāo)準(zhǔn)水樣或超痕量物質(zhì)的分析?？赏ㄟ^將二級(jí)水經(jīng)過再蒸餾、離子交換混合床、0.2μm濾膜過濾等方法處理，或用石英蒸餾裝置作進(jìn)一步蒸餾進(jìn)行制備。② 二級(jí)水；常含有微量的無機(jī)、有機(jī)或膠態(tài)雜質(zhì)，用于精確分析和研究工作。可通過經(jīng)蒸餾、電滲析或離子交換法制備的超純水進(jìn)行再蒸餾的方法制備。③ 三級(jí)水；適用于一般實(shí)驗(yàn)工作?？捎谜麴s、電滲析或離子交換等方法制備。</p><p style="text-indent:25px">活性炭吸附超純水處理：活性炭吸附是利用活性炭的多孔性質(zhì)，使水中一種或多種有害物質(zhì)被吸附在固體表面而去除的方法。活性炭吸附對于去除水中有機(jī)物、膠體、微生物、余氯、嗅味等具有良好的效果。同時(shí)由于活性炭具有一定的還原作用，因此對于水中的氧化劑也具有良好的去除作用。由于活性炭的吸附功能具有一飽和值，當(dāng)達(dá)到飽和吸附容量時(shí)，活性炭濾池的吸附功能將有效降低，因此需要注意分析活性炭的吸附能力，及時(shí)更換活性炭或通過高壓蒸汽進(jìn)行消毒恢復(fù)。但同時(shí)活性炭表面吸附的有機(jī)物有可能成為細(xì)菌繁殖的營養(yǎng)源或溫床，因此活性炭濾池內(nèi)微生物的繁殖問題也值得引起注意。定期的消毒對于控制細(xì)菌繁殖是有必要的。超純水的電子級(jí)水分為五個(gè)級(jí)別，一級(jí)、二級(jí)、三級(jí)、四級(jí)和五級(jí)。</p><div

style="text-indent:25px">蒸餾水、去離子水、超純水、超純水各有什么區(qū)別：天然水中通常含有五種雜質(zhì):電解質(zhì),包括帶電粒子,常見的陽離子有H+、Na+、K+、NH4+、Mg2+、Ca2+、Fe3+、Cu2+、Mn2+、Al3+等；陰離子有F-、Cl-、NO3-、HCO3-、SO42-、PO43-、H2PO4-、HSiO3-等；有機(jī)物質(zhì),如:有機(jī)酸、農(nóng)藥、烴類、醇類和酯類等；顆粒物；微生物；溶解氣體,包括：N2、O2、Cl2、H2S、CO、CO2、CH4等。所謂水的純化,就是要去掉這些雜質(zhì).雜質(zhì)去的越徹底,水質(zhì)也就越純凈1.蒸餾水：就是將水蒸餾、冷凝的水。2.去離子水就是將水通過陽離子交換樹脂（常用的為苯乙烯型強(qiáng)酸性陽離子交換樹脂）,則水中的陽離子被樹脂所吸收,樹脂上的陽離子H+被置換到水中,并和水中的陽離子組成相應(yīng)的無機(jī)酸；3.超純水,是指化學(xué)純度極高的水,其主要應(yīng)用在生物、化學(xué)化工、冶金、宇航、電力等領(lǐng)域,4.、超純水,水的電阻率大于18MΩ*cm（沒有明顯界線）,則稱為超純水.關(guān)鍵是看你用水的純度及各項(xiàng)征性指標(biāo),如電導(dǎo)率或電阻率,PH值,鈉,重金屬,二氧化硅,溶解有機(jī)物,微粒子,以及微生物指標(biāo)等。通過比較不同預(yù)處理手段的供水對超純水系統(tǒng)效能的影響，可以很容易的確證這種作用。云浮超純水代理收費(fèi)標(biāo)準(zhǔn)</p><p
