由于没有公开发表的不使用放射性同位素的定量分析方法，因此尚未对水环境中羟甲基阿特拉津降解产物（HADPs）的命运进行广泛研究。本文提出了一种新的方法，已开发的分析这些降解产物在水中。使用SCX（丙基苯磺酸）阳离子交换固相萃取柱，从加标（1或5 ppb）的实验室水和溪流水样品（0.25 L）中提取、浓缩和纯化三种HADP，羟基阿特拉津（HA）、去乙基氢阿特拉津（DEHA）和去异丙基氢阿特拉津（DIHA
The fate of hydrowylated atrazine degradation products (HADPs) has not been studied extensively in aquatic environments because there are no published quantitative analytical methods that do not use radioisotopes. This paper presents a new method that has been developed to analyze these degradation products in water. Three HADPs, hydroxyatrazine (HA), deethylhydroryatrazine (DEHA), and deisopropylhydroryatrazine (DIHA), were extracted, concentrated, and purified from spiked (1 or 5 ppb) laboratory water and stream water samples (0.25 L) using SCX (propylbenzenesulfonic acid) cation-erchange, solid-phase extraction columns
