Embodiment 1

[0025] Embodiment 1: by figure 2 It can be seen that in CaWO 4 Under the presence and ultrasonic conditions, the degradation rate of ciprofloxacin hydrochloride gradually increased with the addition of 0.5 to 1, and then gradually decreased with the addition of 1 to 2, indicating that CaWO 4 Catalyzed ultrasonic degradation of ciprofloxacin hydrochloride and catalyst is the best when the ratio is 1:1.

Embodiment 2

[0026] Example 2: Change the ultrasonic power to study the effect of degrading ciprofloxacin hydrochloride, in the experiment, CaWO 4 The addition amount of ciprofloxacin hydrochloride was 1.0 g / L, the ultrasonic irradiation time was 120 min, the pH of the dye solution was 6, the concentration of ciprofloxacin hydrochloride was 10 mg / L, and the output power of the ultrasonic device was set in the range of 80-200 W . Depend on image 3 It can be seen that when the ultrasonic power gradually increased, the degradation rate of ciprofloxacin hydrochloride also increased significantly.

Embodiment 3

[0027] Example 3: CaWO 4 The experiment on the degradation rate of ciprofloxacin hydrochloride is carried out at the addition of 1 g / L, the ultrasonic irradiation time is 120min, the concentration of ciprofloxacin hydrochloride is 10mg / L, the pH of the solution is 6, the power of the ultrasonic device for 200W. Take 80 mL of 10 mg / L ciprofloxacin hydrochloride solution, add an accurately weighed certain amount of 1 g / L nano-CaWO 4 powder, stirred magnetically for 30 min in the dark. After the suspension was irradiated by ultrasound for 2 hours, the sample was centrifuged and the supernatant was taken. The degradation rate of ciprofloxacin hydrochloride was 70.75%.

Abstract

The invention discloses a method for degrading antibiotic ciprofloxacin hydrochloride, and relates to a method for degrading antibiotics. By use of a hydro-thermal synthesis method, a tungstate semiconductor material CaWO4 is prepared and is cooperated with an ultrasonic technology for catalyzing medicine preparation waste water simulated by the ultrasonic degradation ciprofloxacin hydrochloride.The ultrasonic degradation is an efficient processing method, which is newly developed at the beginning of 1990, for degrading organic pollutants, and the principle of the processing method is that organic matters are degraded and mineralized by a cavitation effect generated by ultrasound in solution media. Therefore, the cavitation effect of the ultrasonic wave and physical and chemical changes initiated by the cavitation are the root cause of organic matter ultrasonic degradation. The cavitation effect of the ultrasonic wave and physical and chemical changes initiated by the cavitation are combined to degrade the antibiotic ciprofloxacin hydrochloride, and the feasibility of the technology is provided by researches. An experiment proves that the technology has a good effect on the aspectof the ultrasonic degradation of antibiotic wastewater.

Description

technical field [0001] The invention relates to a method for degrading antibiotics, in particular to a method for degrading antibiotic ciprofloxacin hydrochloride. Background technique [0002] With the rapid development of modern industry, how to effectively treat pharmaceutical wastewater has become an important problem to be solved urgently. In particular, antibiotic wastewater is a great threat to humans and the environment. Therefore, this paper intends to study the effect of calcium tungstate as a catalyst on it and under what conditions it can treat antibiotic wastewater more efficiently. Nano-semiconductor materials catalyze ultrasonic degradation of wastewater is a new type of water treatment technology that can completely degrade organic pollutants into CO 2 、H 2 O and other inorganic salts. The use of this technology to solve pollution problems will become an important direction for the development of water pollution control in the future. Its development and a...
