查询词典 dyes

The blue crosslinking polymeric dyes were synthesized with use of leucoquinizarin and polyvinylamine prepared from the Hofmann degradation of polyacrylamide. The maximum wave length was 597nm. The effects of temperature, the concentration of amino group, the pH value and the mole ratio of leucoquinizarin to amino group on the yield of red crosslinking polymeric dye were discussed.

筛选出甲基蓝、藏红和刚果红作为芒果、番石榴和夏橙的最适染色剂，各种染色剂在浓度为0.5%时染色效果较佳，同时对持续冷藏保存后的水果上的产卵孔仍然具有较高的染色率。

Mechanistically, the photocatalytic processes are based on the electron transfer from a excited dyes to the conduction band of TiO〓 semiconductor and subsequent some reactions such as the further reaction of injected electrons with adsorbed oxygen and complicated decomposition processes of dye cationic radicals to lead to dye degradation or mineralization, which offers a feasibility of utilizing inexpensive visible light or most part of solar spectra to treat dye pollutants.

其光催化过程的机理为：染料在可见光下被激发，电子从激发态染料传输到TiO〓半导体的导带，随后发生一系列的反应，如注入的电子与吸附的氧反应以及染料正碳自由基复杂的分解反应导致了染料的降解和矿化，这就为利用廉价的可见光或太阳光中的大部分可见光谱来处理染料污染物提供了可能。

The results indicated that the decoloration of three orcein dyes on EPI-DMA/Bt were much better than on Na-Bentonites. The relationship between adsorptive capacity and equilibrium concentration fitted the isothermal adsorption equations of Langmuir and Freundlich. The adsorption dynamics followed the law of Langmuir equation.

Because of this property, water is preferentially adsorbed by these surfaces, and large organic compounds cannot compete with strongly held water for adsorption sites on the clay surfaces. Thus, Na-clays are ine_ective sorbents for small organic molecules. However, it is possible to modify the surface properties of clays greatly by neutralizing the anionic framework of layer silicates by using positively charged organic species such as alkylammonim ions. In the modi_ed form (HDTMA-bentonite), the clay surface may become organophilic and interact strongly with organic compounds. Textile dyes represent a relatively large group of organic chemicals. In an HDTMA-bentonite-dye system it is possible that adsorption may be enhanced by the hydrophobic interaction between the adsorbed dye molecule and HDTMA-bentonite.
