Schollenberger and simon 就是指他俩在1945年发表的一个检测土壤阳离子交换容量的方法,简称Schollenberger‘s method。具体内容可以参考他们的这篇文章。Determination of exchange capacity and exchangeable bases in soil—ammonium acetate method.网上不容易找到。这个方法的大致意思如下:
Schollenberger’s method has been most commonly used in the measurement of CATION-EXCHANGE CAPACITY(CEC) of soils. This method involves three steps: the first is saturation of sample with NH,+ by washing with IN NH,OAc solution; the second is removal of the excess NH,OAc solution by washing with alcohol; and the third is distillation of retained NH,+ and titration of NH,+ in the distilate. |
