【摘要】：目的建立室内箱式模型,考察水葫芦、水芹、金鱼藻和苞叶芋4种水生植物对模拟水样中环丙沙星、恩诺沙星、呋喃唑酮、氯霉素和孔雀石绿等5种禁用渔药的清除能力。方法分别于第0、1、2、4和6天取培养水样,水样经过滤后,用Cleanert PEP-2固相萃取柱对目标物进行富集、净化,用高效液相色谱仪进行定量分析,流动相为乙腈和体积分数为0.1%的磷酸水溶液(三乙胺调pH为3.0)。结果水葫芦、水芹对环丙沙星、恩诺沙星、孔雀石绿均有一定的清除能力,而对呋喃唑酮和氯霉素清除能力较弱;金鱼藻和苞叶芋对环丙沙星和孔雀石绿清除能力较强,对其他3种药物则清除能力弱。药物对于水葫芦、水芹和金鱼藻的生长有抑制作用,但是对苞叶芋则无明显抑制作用。结论研究所选取的四种植物均对抗生素具有去除能力,且可以耐受药物环境,能够应用于残留药物具有修复作用。
[Abstract]:Objective to establish an indoor box model to study the scavenging ability of four aquatic plants, such as water hyacinth, water celery, goldfish and taro bracts, to five kinds of forbidden fish drugs, such as ciprofloxacin, enrofloxacin, furazolidone, chloramphenicol and malachite green. Methods the cultured water samples were collected on the 0th day and 6th day respectively. After filtration, the samples were enriched and purified by the Cleanert PEP-2 solid-phase extraction column, and the quantitative analysis was carried out by high performance liquid chromatography (HPLC). The mobile phase consisted of acetonitrile and 0.1% phosphoric acid aqueous solution (triethylamine adjusted pH 3.0). Results Water hyacinth, water celery had a certain scavenging ability to ciprofloxacin, enrofloxacin, malachite green, but to furazolidone and chloramphenicol, the scavenging ability of goldfish and taro bracts was stronger to ciprofloxacin and malachite green, but to furazolidone and chloramphenicol. For the other three drugs, the clearance ability was weak. The drug inhibited the growth of water hyacinth, water celery and goldfish alga, but had no obvious inhibitory effect on the bract taro. Conclusion the four plants selected in the study have the ability to remove antibiotics and can tolerate the drug environment and can be used to repair the residual drugs.
