style="text-indent:25px">我們知道水的導(dǎo)電性能，與水的電阻值大小有關(guān)，電阻值大，導(dǎo)電性能差，電阻值小，導(dǎo)電性能就良好。根據(jù)歐姆定律，在水溫一定的情況下，水的電阻值R大小與電極的垂直截面積F成反比，與電極之間的距離L成正比： R=ρ＆#183;L/F 式中ρ為電阻率，或稱比電阻。電阻的單位為歐姆（歐，代號Ω），或用微歐（μΩ），1Ω等于106μΩ電阻率的國際制（SI）單位為歐米（Ω＆#183;M）。如果電極的截面積F做成1CM2，那么電阻值就等于電阻率。水的電阻率的大小，與水中含鹽量的多少，水中離子濃度、離子的電荷數(shù)以及離子的運動速度有關(guān)。因此，超純水電率很大，超純水電阻率就更大,也就說水越純，電阻率越大。連云港超純水價格哪家便宜食品加工行業(yè)用水是離不開超純水的。</p><div

style="text-indent:25px">在原子光譜、高效液相色譜、超純物質(zhì)分析、痕量物質(zhì)等的某些實驗中，需要用超純水，超純水的制備如下：（1）加入少量高錳酸鉀的水源，用玻璃蒸餾裝置進行二次蒸餾，再以全石英蒸餾器進行蒸餾，收集于石英容器中，可得超純水。（2）使用強酸型陽離子和強堿型陰離子交換樹脂柱的混合床或串聯(lián)柱?？沙浞殖ニ械年枴㈥庪x子，其電阻率達10 Q?cm的水，俗稱去離子水，再用全石英蒸餾器進行蒸餾，收集可得超純水。超純水的使用效果還是非常不錯的。</p><p style="text-indent:25px">在超純水的生產(chǎn)過程中，水中的陰、陽離子可用電滲析法、反滲透法及離子交換樹脂技術(shù)等去除；水中的顆粒一般可用超過濾、膜過濾等技術(shù)去除；水中的細菌，目前國內(nèi)多采用加藥或紫外燈照射或臭氧殺菌的方法去除；水中的TOC則一般用活性炭、反滲透處理。在超純水應(yīng)用的領(lǐng)域中，水的純度直接關(guān)系到器件的性能、可靠性、閾值電壓，導(dǎo)致低擊穿，產(chǎn)生缺陷，還影響材料的少子壽命，因此超純水要求具有相當(dāng)高的純度和精度。在超純水的生產(chǎn)過程中，還必需去除一些氣體。為了有效的去除雜質(zhì)，在生產(chǎn)超純水的過程中，加入了一些化學(xué)殺菌劑，如甲醛、雙氧水、次氯酸鈉等。超純水可以完全能夠盡量完全地除去各種殘渣。</p><div
