Abstract

The invention discloses one kind to have absorption antibiotic catalyst method, while having recyclability.Specifically include following steps：Graphene, sodium molybdate, L-cysteine are dissolved in water, the Fe prepared in advance is added after stirring and dissolving into mixed solution3O4Mixed system is finally transferred in water heating kettle and reacts by powder, ultrasonic disperse, and after reaction, resulting product is roasted at high temperature after washing and drying and obtain flower pattern MoS by product centrifuge separation2/Fe3O4/ rGO composite catalyst.Compared with prior art, the method for the present invention, equipment are simple, low in cost, non-environmental-pollution.Resulting magnetic composite shows excellent absorption property and solves the problems, such as that catalyst recycling is difficult, can be widely applied to organic wastewater processing, with good application prospect.

Description

A kind of preparation method for adsorbing antibiotic catalyst
Technical field
The invention belongs to the preparation methods of catalyst material, belong to environmental catalysis and water pollution processing technology field.
Background technique
Since antibiotic is found so far, antibiotic is just liked by our mankind.It cures the disease as civilized society good Medicine.But as we depend on antibiotic unduly, cause all very can easily detect in rivers,lakes and seas all over the world The residual of antibiotic.This to we can the health of the mankind there are also ecological environments all to cause imprint.Tolerance Increasing significantly to pathogenic bacteria and drug resistant gene the antibiotic being simply due in water can be in water environment, thus the ecological balance Threat is received with human health.So the antibiotic in water removal how to be gone to have become for a horse back problem to be solved.Its Middle absorption method is due to various advantages such as easy to operate, inexpensive, high efficiency, the risk generated without highly toxic by-product It is widely paid close attention to, so the research and development with high-efficiency and economic adsorbent as adsorption technology key just seem and its again It wants.
Summary of the invention
It is compound it is an object of the invention to prepare the MoS2/Fe3O4/rGO of the monodisperse flower type structure with recuperability Material.
Technical scheme is as follows：
Firstly, spare with the graphene of 30ml ultrapure water ultrasound 0.25mg/ml.The amount that wherein graphene is added shares 6 kinds, point For：Graphene plus 0.5ml plus 1ml plus 2ml plus 3ml plus 4ml is not added.Then, with 10ml ultrapure water stirring and dissolving 0.121g L-cysteine [HSCH2CH (NH2) CO2H analysis pure] be denoted as " (1) ", with the two of 10ml ultrapure water stirring and dissolving 0.121g Water sodium molybdate（Na2Mo4·2H2O）" (2) " are denoted as, 2) will be added in (1) gradually, continue stirring 30 minutes.By first step ultrasound The graphene of 0.25mg/ml be added in the mixed solution of (1) and (2), ultrasonic 30 minutes.Solution after above-mentioned ultrasonic disperse The Fe3O4 of 2mL (10mg/L) is added.Continue ultrasound 30 minutes.Finally, it is dry to be put into air blast for prepared solution reaction cartridge kettle Dry case, temperature 180oC, the time is for 24 hours.It carries out centrifugal water after taking-up to wash, alcohol, which is washed respectively alternately to clean to be dissolved in dehydrated alcohol three times, to dry in the air It is dry, it is spare to be packed into drug bottle.
Detailed description of the invention：

Fig. 2 .MoS2/Fe3O4/rGO adsorbs antibiotic properties figure
Specific embodiment：Technical solution of the present invention and effect are further described below with reference to embodiment.But made Specific method, formula and explanation are not limitation of the present invention.
The L-cysteine [HSCH2CH (NH2) CO2H analysis pure] of 0.121g, which is denoted as " (1) " and is dissolved in 10mL water, to be stirred It mixes；Simultaneously by the Sodium Molybdate Dihydrate of 0.121g（Na2Mo4·2H2O）Stirring in 10mL water is dissolved in be denoted as " (2) ", it will（2）Add Enter in (1), continues stirring 30 minutes.The graphene of the 0.25mg/ml of first step ultrasound is added to the mixed solution of (1) and (2) In, ultrasound 30 minutes.The Fe3O4 of 2mL (10mg/L) is added in solution after above-mentioned ultrasonic disperse.Continue ultrasound 30 minutes.Most Afterwards, by prepared solution reaction cartridge kettle, it is put into air dry oven, temperature 180oC, the time is for 24 hours.Centrifugal water is carried out after taking-up It washes, alcohol, which is washed respectively alternately to clean to be dissolved in dehydrated alcohol three times, to be dried, and it is spare to be packed into drug bottle.
Case study on implementation 2：
RGO additional amount in case study on implementation 1 is increased into 4ml from 0, other experiment conditions reach maximal absorptive capacity with embodiment 1 The rGO being added is 2ml（0.25mg/L）.
