specific Embodiment approach 1

[0063] Embodiment one: the method for detecting antibiotics in drinking water in this embodiment is carried out according to the following steps:

[0064] 1. Preparation of H 3 dcpcpt rare earth complexes:

[0065]①. Add 3-(3,5-dicarboxyphenyl)-5-(4-carboxyphenyl)-1-hydrogen-1,2,4-triazole to N,N'-dimethylformaldehyde amide, and then add a solution of europium salt with a concentration of 0.01mol / L to 1mol / L, under the condition of a temperature of 140°C to 160°C, conduct a solvothermal reaction for 2h to 96h, filter after the reaction, and wash with water and methanol respectively, Vacuum drying at a temperature of 55°C to 65°C yields H 3 dcpcpt europium complex;

[0066] The mass of 3-(3,5-dicarboxyphenyl)-5-(4-carboxyphenyl)-1-hydrogen-1,2,4-triazole and N,N' -The volume ratio of dimethylformamide is 1g:(150~250)mL; the concentration described in step ① is the europium salt solution of 0.01mol / L~1mol / L and N,N'-dimethylformamide The volume ratio of amides is 1:(60~100)...

specific Embodiment approach 2

[0094] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that in step ①, 3-(3,5-dicarboxyphenyl)-5-(4-carboxyphenyl)-1-hydrogen-1, Add 2,4-triazole to N,N'-dimethylformamide, then add europium salt solution with a concentration of 0.01mol / L to 0.5mol / L, at a temperature of 150°C to 160°C , solvothermal reaction for 2h to 72h, filtered after the reaction, washed with water and methanol respectively, and dried under vacuum at a temperature of 60°C to 65°C to obtain H 3 dcpcpt europium complex;

[0095] The mass of 3-(3,5-dicarboxyphenyl)-5-(4-carboxyphenyl)-1-hydrogen-1,2,4-triazole and N,N' -The volume ratio of dimethylformamide is 1g:(150~200)mL; the concentration described in step 1. is the europium salt solution of 0.01mol / L~0.5mol / L and N,N'-dimethyl The volume ratio of formamide is 1:(60-80). Others are the same as in the first embodiment.

specific Embodiment approach 3

[0096]Specific embodiment three: the difference between this embodiment and specific embodiment one or two is: in step one ②, 3-(3,5-dicarboxyphenyl)-5-(4-carboxyphenyl)-1 -Hydrogen-1,2,4-triazole is added to N,N'-dimethylformamide, and then gadolinium salt solution with a concentration of 0.01mol / L~0.5mol / L is added, and the temperature is 150℃~ Under the condition of 160°C, solvothermal reaction for 2h to 72h, after the reaction, filter, wash with water and methanol respectively, and dry under vacuum at a temperature of 60°C to 65°C to obtain H 3 dcpcpt gadolinium complex;

[0097] The mass of 3-(3,5-dicarboxyphenyl)-5-(4-carboxyphenyl)-1-hydrogen-1,2,4-triazole and N,N' -The volume ratio of dimethylformamide is 1g:(150~200)mL; the concentration described in step 1② is the gadolinium salt solution of 0.01mol / L~0.5mol / L and N,N'-dimethyl The volume ratio of formamide is 1:(60-80). Others are the same as those in the first or second embodiment.

Abstract

The invention provides a method for detecting antibiotics in drinking water to solve the problem that the existing fluorescent detecting article cannot achieve detection of a plurality of targets. Themethod includes the first step of preparing an H3dcpcpt rare earth complex; the second step of preparing an H3dcpcpt rare earth complex solution; the third step of conducting H3dcpcpt rare earth complex fluorescence detection; the fourth step of conducting drinking water fluorescence detection; the fifth step of calculating. The method is used for detecting the antibiotics in the drinking water.

Description

technical field [0001] The invention relates to a method for detecting antibiotics in water. Background technique [0002] Antibiotics are mainly secondary metabolites or synthetic analogs produced by bacteria, molds or other microorganisms. After the 1990s, scientists expanded the scope of antibiotics, collectively referred to as biopharmaceuticals. It is mainly used to treat various bacterial infections or diseases caused by pathogenic microorganisms. Generally, it will not cause serious side effects to the host. Due to the mass production of antibiotics and illegal sewage discharge, antibiotics in drinking water in our country often exceed the standard and cause a series of health problems. [0003] At present, the common method for detecting antibiotics is spectroscopic detection based on chromatography technology. However, these technologies all require expensive instruments, professional personnel and long test time, making it difficult to detect in real time and on...
