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；有機物質(zhì),如:有機酸、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,溶解有機物,微粒子,以及微生物指標(biāo)等。</p><p

以下，pH為2-11的條件下長期連續(xù)使用。取用超純水時應(yīng)使用一些開口比較小的容器，這樣可以盡量減少空氣進入瓶內(nèi)，減少污染。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

MF )超純水處理、活性炭吸附超純水處理、反滲透(RO )超純水處理、離子交換(IX)超純水處理、紫外線(UV)超純水處理等。超純水處理I藝比較多,目前,超純水處理行業(yè)對于超純水處理也是比較成熟的階段。超純水的處理要根據(jù)用戶的需求來確定之后的超純水處理方案。超純水就是指化學(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。黃浦區(qū)超純水哪家好</p><p
