Abstract
The invention belongs to the technical field of sewage treatment, and particularly relates to a preparation method and application of modified pyrite powder with photocatalytic performance. The method comprises the steps of bonding pyrite powder on the bonding surface of an adhesive tape, placing the adhesive tape in silane hydrolysate for reaction, taking out, cleaning, drying and removing the adhesive tape to obtain silane-treated pyrite; and reacting the silane-treated pyrite with an anthraquinone compound, filtering out solids, cleaning and drying to obtain the modified pyrite powder with photocatalytic performance. The modified pyrite with photocatalytic performance can effectively degrade heavy metal ions and promote the degradation rate of microorganisms on nitrate, azo dyes and the like, and has a good application prospect.
Description
Technical Field
The invention belongs to the technical field of sewage treatment, and relates to a preparation method and application of modified pyrite with photocatalytic performance.
Background
Sewage, including industrial wastewater, domestic sewage, etc., has become one of the important pollutants that destroy the environment and affect human health. Pyrite, because of its photocatalytic activity, has been used in the treatment of some effluents to remove some organic pollutants or heavy metal ions.
Anthraquinone compounds have been reported to be used for the microbial degradation of sewage containing nitrate, azo dyes and the like, and can promote and increase the degradation rate of the nitrate and the azo dyes by the microorganisms.
Further increasing the degradation rate of nitrates, azo dyes, etc. remains the direction of industry efforts.

The invention has the beneficial effects that: according to the invention, the pyrite powder is firstly bonded by the adhesive tape, so that when the pyrite powder reacts in the silane hydrolysate, the part of the surface which is not bonded by the adhesive tape reacts, and the part of the surface which is bonded by the adhesive tape does not react, therefore, the surface of the pyrite powder is half-coated by the silane. The part of the pyrite surface which is semi-coated by the silane continuously reacts with the anthraquinone compound, and the part which is not coated cannot react with the anthraquinone compound, so that a semi-coating structure of the anthraquinone compound on the pyrite powder is formed. The uncoated part of the pyrite powder body with the semi-coating structure can absorb ultraviolet light to generate photocatalytic activity, and the coated part can prevent the pyrite from absorbing the ultraviolet light due to the existence of the coating, so the modified pyrite powder body has photocatalytic performance, can generate degradation effect on heavy metal ions under the irradiation of the ultraviolet light, has obvious effect, and can promote the improvement of the microbial degradation rate of nitrate, azo dyes and the like under the irradiation of the ultraviolet light. Therefore, the modified pyrite with photocatalytic performance has better effects on the reduction treatment of heavy metals and the degradation of nitrate and azo dyes.
