摘要： In the invention, a back titration and titer determination can be made using a back coulometric titration. When the iodine exists in a solution put in the titration flask with electrolytic electrodes, a back coulometric titration is performed to produce iodine ions from the iodine at the anode of the electrolytic electrodes. Where the solution is a dehydrated solvent including a Karl Fischer reagent for a volumetric titration, the titer can be determined by the back coulometric titration. Where the solution is anolyte in which the iodine remains after the coulometric titration in the coulometric titration method, the water content in the sample is found from the quantity of electricity consumed by the coulometric titration and the quantity of electricity consumed by the back coulometric titration. Where the solution is anolyte in which the iodine remains by adding Karl Fischer reagent in the volumetric titration method, the water in the sample put in the titration flask is found from the added amount of Karl Fischer reagent and the quantity of electricity consumed by the back coulometric titration.
摘要翻译：在本发明中，可以使用反向电量滴定法进行反滴定和滴定度测定。当放置在具有电解电极的滴定瓶中的溶液中存在碘时，进行背电量滴定以从电解电极的阳极处的碘产生碘离子。当溶液是包含用于体积滴定的卡尔费休试剂的脱水溶剂时，滴定度可以通过后面的库仑滴定测定。如果溶液是在库仑滴定法中在库仑滴定之后碘保留的阳极电解液，则样品中的水含量是从库仑滴定消耗的电量和由后面的库仑滴定消耗的电量中找到的。当溶液是通过在体积滴定法中加入卡尔费休试剂而残留碘的阳极液时，从卡尔费休试剂的加入量和背部消耗的电量中可以发现放入滴定瓶中的样品中的水库仑滴定。
