为了研究胺唑草酮的光解规律及其对环境的影响,笔者采用液液分配-高效液相色谱法,通过室内模拟试验研究胺唑草酮在不同自然水体、不同p H缓冲溶液、不同表面活性剂、不同浓度腐殖酸中的光解动态。研究结果表明:胺唑草酮在碱性条件下光解最快,中性条件次之,半衰期分别为2.9 h和6.4 h。在酸性条件下最缓慢,半衰期为7.6 h。胺唑草酮在4种不同类型水体中的光解速率顺序为:河水>稻田水>湖水>蒸馏水。胺唑草酮在不同浓度腐殖酸中的光解半衰期分别为1.3、3.5和5.8 h。在不同表面活性剂试验中,胺唑草酮在Span 60中的光解最快,十二烷基苯磺酸钠次之,在Tween 80存在的条件下降解最慢,其半衰期分别为2.1、2.5、10.2 h。可得出结论,胺唑草酮在碱性和中性环境中不稳定;在河水中能较快光解;低浓度腐殖酸对胺唑草酮的光解有促进作用;在Span 60存在的条件下最不稳定。
In order to study the law of photolysis of oxaliplatin and its impact on the environment, the author used liquid-liquid partitioning-high performance liquid chromatography to study the effects of oxacarbone in different natural waters and different p H buffer solutions by laboratory simulation Surfactant, photolysis dynamics in different concentrations of humic acid. The results showed that: under the alkaline conditions, ecotoxins photodegradation fastest, followed by neutral conditions, half-life of 2.9 h and 6.4 h. Under acidic conditions, the slowest, half-life of 7.6 h. The order of photodegradation rates of amikacin in four different types of water was river water> paddy water> lake water> distilled water. The photolysis half-lives of oxamizole in different concentrations of humic acid were 1.3, 3.5 and 5.8 h, respectively. In different surfactant tests, the photodegradation of amikacin was the fastest in Span 60, followed by sodium dodecylbenzenesulfonate, the slowest degradation in the presence of Tween 80, the half-lives were 2.1, 2.5, 10.2 h. It can be concluded that, in the alkaline and neutral amoxicillin instability in the environment; faster photolysis in the river; low concentrations of humic acid on the photolysis of the eczema has a role in promoting the presence of Span 60 The most unstable conditions.
