草甘膦是一种非选择性、广谱、应急后除草剂，受《安全饮用水法案》监管。根据Sprankle等人的测定，草甘膦是两性离子，其pKa值小于2.0、2.6、5.6和10.6。与天然物种的络合是一个重要课题，因为合成的物种可能表现出与未结合污染物不同的处理特性。本文试图测试各种处理工艺对草甘膦的有效性，并探讨络合现象是否可能影响结果。

Glyphosate is a non-selective, broad-spectrum, post emergent herbicide that is to be regulated by the Safe Drinking Water Act. Glyphosate is zwitterionic with pKa values of less than 2.0, 2.6, 5.6, and 10.6 as determined by Sprankle et al. Complexation with natural species is an important topic because of the resultant species may exhibit different treatment characteristics than the unbound contaminant. This paper attempts to test the effectiveness of various treatment processes on glyphosate, and looks into whether the complexation phenomena may be affecting the results.
