DIN 38409-7-2005 水、废水和淤泥检验的德国标准方法.效应和物质的参数特性(H组).第7部分:酸碱度的测定(H7)
German standard methods for the examination of water, waste water and sludge - Parameters characterizing effects and substances (group H) - Part 7: Determination of acid and base-neutralizing capacities (H 7)
This standard specifies six methods for determination of acid and base capacity in water. It describes the methods for determination of acid capacity to pH 8,2 and pH 4,3 and base capacity to pH 4,3 and pH 8,2 by titration with and without addition of masking agent tartrate citrate solution as well as by back titration.
