Secondly, this paper describes the effect of presence of inorganic salts namely, sodium chloride, sodium sulphate, sodium nitrate, sodium dihydrogen phosphateand and sodium bicarbonate on decolouration of azoic dye effluents by the UV-Vis /Ferrioxalate/H2O2 process.

本课题可以得到以下结论：在偶氮染料光催化氧化脱色反应中，无机盐有抑制作用，并且依其种类不同，其抑制作用亦有差异；表面活性剂对于染料的脱色降解存在不同程度上的抑制作用。

The results from the study on the decoloring conditions of strain 3# showed that the pH range for decoloring reaction was 5～11 with 6 ～7 being the optimum, the temperature range was 10～30℃ with 30℃ being efficiency optimal. The decoloring efficiency was higher under the presence of oxygen than that lack of oxygen. Strain 3# could more strongly decolor malachite green under optimum conditions. The decoloring rate was above 50%, 70% and 90% in 4, 12 and 24 h treatment, respectively.

对3#菌株的脱色反应条件进行初步研究表明，3#细菌的脱色反应的pH为5～11，最佳范围pH 6～7；温度10～30℃，最佳温度30℃；有氧气情况下的脱色效果较缺氧情况下好；在最佳条件下该菌对孔雀绿染料的脱色作用较强，处理4、12、24 h后，色度去除率分别达到50%以上、70%以上和90%以上。

It was found that water hyacinths have the ability to decolor several kinds of dyes including cation, actived, direct, reduced and acid dyes and the decoloring rate of the plant for cation dyes was up to 97%.

经凤眼莲对染料色水的脱色作用静态试验表明，凤眼莲对阳离子、活性、直接、还原和酸性等染料有显著的脱色作用，其中对阳离子染料的脱色尤为有效，脱色率最高可达98％。

Chemical decolorizer can be used to simulate vitiligo animal pathological pattern.

用化学脱色法处理的动物有模拟白癜风的作用。

The results show that when molar ratio of epichlorohydrin and dimethylamine is set as 1.5:1 and the amount of 1,2-diaminoethane is 3%, polyamine flocculants get the best viscosity and cationic degree and have excellent decoloration efficiency through the adsorption and subsequent formation of particle-polymer-particle bridges.

结果表明，环氧氯丙烷和二甲胺的摩尔比为1.5：1，乙二胺加入量为3%时，聚合物的粘度和阳离子度最大，具有较强的吸附架桥和电中和作用，对染料废水有较好的脱色效果。

In addition, ultrafiltration contributed to the decolouring of pectin extract.

同时，超滤对果胶液的脱色有良好作用。

UV and SMPE-GC-MS results confirmed that radical-oxidation and hightemperature pyrogenation controlled the sonochemical-oxidation of toluene, and mainmiddle-products included benzaldehyde, bibenzyl, dibutyl phthalate, et al., final products werecarbon dioxide and water. The reactive violet K-3R was chosen as a model compound to study the effect ofsonoelectrochemical degradation of nonvolatile pollutant.

以超声与电化学作用处理活性紫K-3R水样，二者协同效应明显，5V槽电压时60min K-3R脱色效率要比纯电场作用时高57.8％，纯超声场对活性紫基本无显著的降解作用，初始浓度、pH对超声电化学协同降解影响较大，实验建立了活性紫降解的动力学模型，经超声电化学处理后，K-3R共轭发色体系已基本被破坏，但溶液中仍有苯环等产物。

Through a variety of resin filter, adsorption and elution conditions for the optimization, as well as decolorization, crystallization methods of research, this article eventually determine the strong acid cation resin HZ-001 which is at pH 3, 3BV / h, having the largest adsorption to the tryptophan; the fermentation broth were centrifuged to remove sediment,then treated with activated carbon to be decolored and then treated with strong acid cation resin HZ-001. After that,2mol/l amino acid were passed through the HZ-001 ion exchanging column,kept almost constants when the flow rate stayed 6 BV / h. At 60℃,it was condensed into the saturated state and then added Ethanol until its percentage reaching 30%. At 4 ℃ under 100rpm placed in the shaker 20h, the collection of L-tryptophan was dried up in vacuo.

本文通过对种树脂的筛选、吸附和洗脱条件的优化，以及对脱色、结晶方法的研究与摸索，最终确定强酸型阳离子树脂HZ-001在pH=3，3倍床体积流速，温度室温，对色氨酸有最大的吸附作用；将发酵液离心去沉淀并用活性炭脱色后通过HZ-001强酸型阳离子交换树脂柱，再用2mol/L的氨水6倍床体积流速在室温下进行洗脱，收集洗脱液，60℃浓缩为过饱和状态后加入30%无水乙醇，4℃下100rpm摇起晶20h，过滤搜集结晶并真空干燥得白色粉片状L-色氨酸晶体。
