一般描述
助留机理:反相
样品基质相容性:含水溶液(饮用水、地下水、废水)
样品基质相容性:含水溶液(饮用水、地下水、废水)
- 多点键合,十八烷基 (17%C)(封端)
- 非常适用于从含水环境样品中净化、萃取和浓缩污染物
- 更高的 17%C 含量可得到更大的键合能力以及更高的回收率
- 更高的碳含量也可提供更好的耐极端 pH 条件的性能
- 用于从废物中提取除草剂、杀真菌剂和杀虫剂
固相萃取装置使用玻璃瓶或管进行样品收集和浓缩。在这种情况下使用SPE管时,一些吸附剂需要比小型SPE柱更大的解吸体积。
应用
Supelclean™ ENVI™-18 SPE管可在SPE中使用,以纯化沿海沉积物样品。它还可用于鉴定阿特拉津的降解产物。

The present study investigates the degradation of atrazine (2-chloro-4-(ethyl amino)-6-isopropyl amino-s-triazine) in aqueous solution by a developed new method, namely by means of a microwave-assisted electrodeless discharge mercury lamp (MW-EDML). An experimental design was conducted to assess the influence of
