Abstract

The invention discloses a method for degrading musk ketone under natural light by utilizing titanium dioxide/charcoal hybrid aerogel. The method comprises the following steps: with titanium tetrachloride as a precursor, absolute ethyl alcohol as a solvent, resorcinol and furfural as precursors of an organic phase, propylene epoxide as an inducer of network gel and ethyl acetoacetate as a complexing agent, preparing a titanium dioxide/charcoal hybrid aerogel material by a one-step sol-gel method; adding the dioxide/charcoal hybrid aerogel into wastewater containing musk ketone to have degradation reactions under the condition of natural light, wherein a dark reaction is carried out firstly for 15 minutes, and the following light reaction lasts for 60-90 minutes under the condition of natural light. The method for degrading musk ketone under the natural light by utilizing titanium dioxide/charcoal hybrid aerogel is convenient to operate; compared with a traditional degradation method, the method disclosed by the invention has the advantages that the degradation time is short, degradation can be performed under natural light, and the degradation rate is high.

Description

technical field [0001] The invention belongs to the field of waste water treatment, in particular to a method for degrading musk ketone by using titanium dioxide / carbon hybrid airgel under natural light. Background technique [0002] Pharmaceutical and Personal Care Products (PPCPs for short). As a new pollutant, PPCPs have been paid more and more attention. Many PPCPs components have strong biological activity, optical rotation and polarity, and most of them exist in the environment in trace concentrations. The use of veterinary medicine, agricultural medicine, human medicine and cosmetics is the main way it is introduced into the environment. Urban sewage is an important resource, and its treatment will directly affect the health of the human body and the water quality of the receiving water body. Most of the PPCPs are discharged into the sewage in the original or transformed form along with the sewage entering the sewage treatment plant. Both Europe and North America ...
