Color-deepening finishing agent for dyed polyester textiles

The invention relates to a color-deepening finishing agent for dyed polyester textiles. Nano-titanium dioxide particles serving as solids and an amino modified polyorganosiloxane microemulsion serving as a film-forming material are compounded to form the color-deepening finishing agent for the polyester textiles. Due to the small grain size effect and the large specific surface area of the nanoparticles, the contact of the nanoparticles with fibers is increased and a relatively high adsorption rate can be formed; due to the flexibility and the film-forming property of the organic silicon junction fragment of the film-forming material covering the nanoparticles, the color-deepening finishing agent is capable of forming an uneven thin film capable of generating scattering reflection on the surface of the treated fabric, and consequently, the absorptive amount of the fabric to the incident light can be greatly increased, the reflected light can be reduced and the effect of enhancing the color depth of the fabric can be achieved. The dyed polyester textiles treated by use of the color-deepening finishing agent are deepened in color under the circumstance that the inherent characteristics of the dyed fiber products are not damaged; besides, the treated dyed polyester textiles have good color fastness and also have antibacterial property.

Treatment method of thallium-containing wastewater

The invention discloses a treatment method of thallium-containing wastewater. The method comprises the following steps: A) respectively preparing magnetic adsorbents rGO-Fe3O4@TiO2 and PS; B) obtaining a thallium-containing wastewater sample, and measuring the concentration and pH value of thallium in the sample; C) calculating and verifying the optimal adding amount of the rGO-Fe3O4@TiO2 and PS; D) adding rGO-Fe3O4-coated TiO2 and PS into the wastewater according to the optimal adding amount. The rGO-Fe3O4@TiO2 material effectively activates PS to generate SO4 free radicals through -COOH groups of the rGO-Fe3O4@TiO2 material and Fe (II) in magnetic particles, Tl (I) is quickly adsorbed and oxidized into Tl (III), the Tl (III) is precipitated, and the Tl (I) in wastewater is efficiently removed. According to the invention, a novel magnetic adsorbent is adopted, and is a composite structure rGO-Fe3O4@TiO2 formed by taking Fe3O4 as a core, coating core-shell solid particles with TiO2 nanoparticles on the surface, taking an rGO nanosheet with mesopores as a carrier and combining the core-shell solid particles and the carrier with the nanosheet. According to the thallium-containing wastewater treatment method provided by the invention, the adopted adsorbents are few in variety and total amount, high in thallium adsorption capacity, large in capacity, high in efficiency, low in cost and easy to popularize.
