Abstract

The invention discloses an oil body-polypyrrole solar energy absorbing material, which is prepared by the following method: 1) adding vegetable oil body into a pyrrole solution, uniformly stirring the solution, and centrifuging the solution; 2) adding the oil body obtained in the step 1) into a ferric chloride solution, stirring for reaction, and centrifuging the solution to obtain an oil body-polypyrrole solar energy absorbing material; and 3) freeze-drying the material. By utilizing the method, the recovery rate is high; the synthesized oil body-polypyrrole solar absorbing material is stable in state and more in cycle index; the results show that the collected fresh water does not contain bacteria and is effectively purified, and the water quality is good; meanwhile, the conductivity is low, and the impurity content is low. According to the invention, the characteristic that the oil body is used as a light carrier is utilized, pyrrole molecules are subjected to in-situ polymerization to form the oil body-polypyrrole solar energy absorbing material, and undrinkable water such as domestic sewage, river water, seawater and the like can be effectively converted into high-quality fresh water resources under the irradiation of solar energy, so that the low-cost and high-efficiency fresh water resource regeneration can be realized.

Description

technical field [0001] The invention belongs to the technical field of solar energy and water treatment, and in particular relates to an oil body-polypyrrole solar absorbing material and a photothermal evaporation water purifier. Background technique [0002] At present, the shortage of fresh water resources has become a global problem, coupled with the serious water pollution caused by industry, agriculture, domestic wastewater, etc., making the problem of fresh water resource shortage even more serious. According to statistics, more than one billion people in the world are suffering from water shortage. Although more than 70% of the earth's surface is covered by water, fresh water resources only account for about 3%, and there are only a handful of fresh water resources that can be directly used by humans. Therefore, it is imminent to convert various water sources that cannot be directly used into fresh water resources that can be directly used. Traditional water desalin...
