什麼是卡爾費歇爾法?
如下面化學反應公式(1)所示,卡爾‧費歇爾法使用卡爾‧費歇爾試劑測定水分含量,該試劑定量地、有選擇性地與水發生反應。卡爾‧費歇爾試劑的組成成分是碘、二氧化硫、鹽基和醇類等溶劑。
I2 + SO2 + 3 Base + ROH + H2O → 2 Base‧HI + Base‧HSO4R…….(1)
如下所述,這種方法可以用於容量及庫倫滴定系統。
圖1:
庫倫測定庫倫滴定
用庫倫滴定法滴定。將試樣加入電解液中,其主要成分是碘化物離子、二氧化硫、鹽基以及醇類等溶劑。如公式(2)所示,通過電解氧化作月產生碘,直接與卡爾‧費歇爾試劑發生反應。
2I--2e→I2…….(2)
按照法拉第定律,碘的產生與電量成正比。這就意味著,含水量可以從電解氧化所需庫倫數直接得出來。
1mg的水=10.71庫倫
如圖1所示,需要兩種類型的庫倫試劑:一種是陽極電解液,置電解槽的陽極室中,另外一種是陰極電解液,置於電解槽的陰極室中。庫倫試劑不需要標定。另一個優點是可以反複使用。
容積滴定容量滴定
在一個燒中放入適合於試樣的脫水溶劑。用滴定劑從該溶劑中轉移所有的水分。然後,加入試樣。用滴定劑進行滴定,滴定量(mgH2O/mL)是事先生確定的。試樣的水分含量由滴定容量(mL)確定的。使用恒定電流極化電壓法檢測終點。圖2顯示了典型的在市場上銷售的自動容積滴定系統的各個組成部分。

CA-200《Dual Channel Measurement & Dual Channel Display》 |
The dual channel Karl Fischer Moisture System has further development to complete the system. One unit of system perfectly cover the function of two systems by using Color LCD display. And more over the foot print is much smaller than two units.
Dual Channel Simultaneous Measurement (Patent Pending)
Simply adding a titration unit to the CA-200/KF-200 single channel system makes it possible to configure a dual channel system. The 5.7-inch color LCD clearly show the status of both channels.
