常見問題
什么是氨氮總磷總氮?
[2018-04-27]
氨氮是指水中以游離氨(NH3)和銨離子(NH4+)形式存在的氮。
什么是水質(zhì)COD
[2018-04-23]
什么是水質(zhì)COD?是化學(xué)需氧量。所謂化學(xué)需氧量,是在一定的條件下,采用一定的強氧化劑處理水樣時,所消耗的氧化劑量。它是表示水中還原性物質(zhì)多少的一個指標(biāo)。
COD消減量是什么意思?
[2018-04-23]
有機污染物排放量一般以COD計算,就是說COD消減量可以理解成有機污染物消減量。
實驗室測定COD的儀器有哪些?
[2018-04-16]
實驗室的COD測定儀主要分為兩種類型,一是采用分光光度法,另一種是采用電化學(xué)法。
測量水中溶解氧時是否需要攪拌樣品?
[2018-04-16]
因為水中溶解氧測量過程是一個消耗氧氣的過程,所以在現(xiàn)場測量時,如果水樣有一定的流速,可以保持探頭不動。如果水樣是靜止的,則應(yīng)將探頭上下移動,以保證測量結(jié)果的準(zhǔn)確性。
可以稀釋樣品測定COD嗎?
[2018-04-13]
可以的。向瓶中加入合適的稀釋樣品量,將最終檢測結(jié)果乘以你的稀釋倍數(shù)。
如何驗證COD檢測結(jié)果的精確度?
[2018-04-13]
使用一個濃度落在你所使用的濃度范圍內(nèi)的COD標(biāo)準(zhǔn)溶液,將這個標(biāo)準(zhǔn)溶液當(dāng)作你的樣品一樣進(jìn)行檢測。
COD檢測誤差的主要因素是什么?
[2018-04-13]
氯是COD檢測中帶來影響最大的因素,在重鉻酸鉀法測定COD的實驗瓶中使用硫酸汞能夠去除氯的干擾。
雜散光對測量結(jié)果的影響?
[2018-04-11]
雜散光使得多余的散射光進(jìn)入樣品檢測儀器中,造成測量結(jié)果偏高。
濁度測量中那些因素會導(dǎo)致誤差?
[2018-04-11]
濁度測量中會導(dǎo)致誤差的主要因素有以下幾種:樣品池有污垢;樣品不匹配;樣品中有氣泡。
PH電極讀數(shù)不穩(wěn)定怎么辦?
[2018-04-11]
PH電極讀數(shù)不穩(wěn)定,一般采取活化處理、甩出氣泡、增加鹽酸溶液等;若果選型不對,則需要重新選型。
PH計無法校正,只顯示7
[2018-04-11]
校正和測量樣品時, pH計只顯示7。但校正時,它還顯示error 2或3 ,該怎么辦?
在進(jìn)行pH測試時,探頭與儀器設(shè)置應(yīng)注意哪些問題?
[2018-04-11]
PH內(nèi)置校準(zhǔn)程序有些是分組或者是分各國標(biāo)準(zhǔn)的,要根據(jù)需要自己調(diào)節(jié),一般有以下兩個關(guān)鍵設(shè)置應(yīng)特別加以注意:探頭與儀器接口方式設(shè)置,探頭自動識別的中性pH標(biāo)準(zhǔn)溶液的設(shè)置。
COD檢測限值的適用范圍是多少?
[2018-04-11]
一般較為精密的COD測量儀器是在350nm下校正為0-40mg/L范圍,420nm下0-150mg/L范圍,620nm下0-1500mg/L和0-15000mg/L范圍。
在滴定法測溶解氧時怎樣防止出現(xiàn)氣泡?
[2018-04-09]
當(dāng)按照溫克勒溶解氧滴定方法操作時,試著在瓶子上方2到3英寸的高度將塞子落下,或者快速地猛推塞子以避免空氣的進(jìn)入。
