固定数码相机拍摄设置，在同样光强度但投射方向不同下拍摄同一色标，比教色标上同样点的色度值，检测色度值是否发生变化及其规律。

The fact that wastewater has higher chromaticity removal efficiency in acid medium than in basic medium indicates that H+ ions play an important role in chromaticity removal ,possibly by a mechanism of deoxidation in which H+ ionsreact with the organic compound of pollutants in wastewater and cause the chain rupture of chromophoric or anxochromic groups from the organic compound molecules.

事实已经废水色度去除效率高，比在酸性介质中显示基本氢离子色度去除起到了重要作用，可能的机制脱氧其中氢离子的反应有机化合物废水和污染物链条断裂造成anxochromic色或团体从有机化合物分子。

After the combined treatment performed at pH=4.0, using 2.5 of TiO2 for 8 min of adsorption and 20 mg/L of ClO2 for 2 min of oxidation, the treated sample was dischargeable under the existing discharge limits for dyeing wastewater; the starting COD was reduced from 750 mg/L to〈100 mg/L and that the wastewater color was reduced from 250 dilutions to 40 dilutions.

结果表明，对于COD为750mg／L、色度为250倍、SS为100mg／L的1000mL印染废水，当溶液pH为4.0、ClO2用量20mg／L、TiO2复合吸附剂用量2.5g、反应时间和吸附时间分别为2、8min时，处理后的废水COD＜100mg／L、色度〈40倍、SS＜70mg／L，达到了《纺织染整工业水污染物排放标准》（GB4287—92）排放要求。

The results show that the particles in the two phosphor samples are overall spherical-shaped with a mean size of ~300 nm, and their main emission peaks under 147 nm VUV excitation are located at 619 nm. In comparison with Y0.95Eu0.05PO4 phosphor, Y095Eu0.05 (P0.2V0.8)O4 phosphor is a more promising candidate for red-emitting PDP phosphor application due to its higher homochromy and its chromaticity coordinates closer to flammulated chromaticity coordinates (0.67, 0.33) regulated by National Television Standard Committee.

结果表明，制得的Y0.95Eu0.05P(下标 1-xVO4(x：0，0.8)荧光粉的粒径约为300nm，在147nm真空紫外激发下，发射光谱的主峰位于619nm；与Y0.95Eu0.05PO4荧光粉相比，Y0.95Eu0.05(P0.2V0.8)O4具有更好的色纯度，它的色度坐标更接近国际电视标准委员会规定的红色色度坐标(0.67， 0.33)，是具有很好应用前景的PDP红色荧光粉。
