<p>氨氮測(cè)定儀適可以快速、準(zhǔn)確測(cè)定廢水中氨氮的濃度。冷光源、窄帶干涉、光源壽命達(dá)10萬(wàn)小時(shí)；同時(shí)支持比色皿和比色管兩種比色方式；氨氮測(cè)定儀采用大屏液晶顯示、濃度直讀，中文顯示界面、全中文鍵盤(pán)；支持歷史數(shù)據(jù)存儲(chǔ)，用于大、中、小型水廠、工礦企業(yè)、生活用水、工業(yè)用水的氨氮濃度檢測(cè)，以便控制水的氨氮達(dá)到規(guī)定的水質(zhì)標(biāo)準(zhǔn)。</p><p> 氨氮測(cè)定儀測(cè)定中應(yīng)留意這些事：</p><p> 1、對(duì)于污染嚴(yán)重的水樣，特別是工業(yè)污染源的水樣，可選取所需體積的1/10的試料和1/10的試劑，放入10×150mm的硬質(zhì)玻璃試管中，用酒精燈加熱至沸數(shù)分鐘，觀察溶液是否變?yōu)樗{(lán)綠色，若呈現(xiàn)藍(lán)綠色的話，應(yīng)再適當(dāng)?shù)纳偃≡嚵?，重?fù)以上實(shí)驗(yàn)，直至溶液不再變藍(lán)綠色為止。以此確定待測(cè)水樣合理的稀釋倍數(shù)。稀釋時(shí)，所取廢水樣量不得少于5mL，如果化學(xué)需氧量很高（如工廠車(chē)間廢水），則廢水樣應(yīng)多次稀釋。</p><p> 2、水樣的氧化回流應(yīng)該在通風(fēng)櫥內(nèi)進(jìn)行，以防Cl?之類(lèi)的有害氣體妨礙操作人員的健康。</p><p> 3、在標(biāo)準(zhǔn)方法中，回流溫度為145～148℃，冷卻水的流量應(yīng)控制在用手觸摸冷凝管外壁不能有溫感，否則水樣中的低沸點(diǎn)有機(jī)物也會(huì)揮發(fā)損失，使測(cè)定結(jié)果偏低。水樣回流消解結(jié)束后，加入蒸餾水或去離子水應(yīng)從冷凝管上方緩慢加入，以便將附著在管內(nèi)壁的揮發(fā)性有機(jī)物沖到試液中。在使用閉管催化-氧化法快速處理水樣時(shí)，也應(yīng)在加熱完畢后，趁熱顛倒管內(nèi)水樣，使得氣相中的有機(jī)物參與氧化反應(yīng)。</p><p><br/></p><p><br/></p><p>想要了解有關(guān)水質(zhì)測(cè)定儀請(qǐng)聯(lián)系我們：河南綏凈環(huán)?？萍加邢薰?/p>
