Shenyang Research Institute of Chemical Industry, Shenyang 110021, China Abstract: Spectrophotometric analysis showed that the peak absorbance for food dye of Allura Red and biological dye of Ponceau-G occurred at 501 and 510 nm. In sunlight after 2, 4, 6, 8, 10 hours, the decomposition rates of Allura Red and Ponceau G were between 2.4 to 5.8% and 3.4 to 10.8%, so they are stable in sunlight. The recovery rates on cottons and glasses were very high, so they are easily recoveried from targets. Further studies showed that the recovery rates of two dyes on the leaves of wheat, cabbage, cucumber and tomato were different, so it need previously determine the recovery rate of tracer on the target crop to adjust the result. Field experiment showed it was easy to measure the pesticide spray distribution of high volume spay and low volume spray to use Allura Red and Ponceau-G as tracers.

沈阳化工研究院，沈阳 110021 摘要：光谱分析表明，食品染色剂诱惑红和生物染色剂丽春红-G的最大吸收波长分别为501 nm和510 nm ；在连续2、4、6、8、10 h阳光照射下，分解率分别在2.4%~5.8%和3.4%~10.8%之间，见光稳定性良好；两种染色剂在棉花叶片和玻璃片上的洗脱回收率都很高，说明易于从靶标上洗脱下来；进一步测定表明，两种染色剂在小麦、甘蓝、黄瓜、番茄叶片上的洗脱回收率各不相同，所以对准备进行测试的作物应先做一次洗脱回收率试验，用以校正测试结果；田间应用表明，用两种染色剂做示踪剂，可以方便地测定常量喷雾和低容量喷雾过程中农药在麦田的沉积分布情况。

Another remarkable characteristic of printing and dye the waste water is that the colour is high, is it adopt biological carbon pool is it is it deal with to decolour to go on to it , for activated carbon absorbent spent to design originally, active charcoal adsorption method to utilize porous active charcoal material make one or many kinds of material of waste water it absorbs to be that surface get rid of in active charcoal.

Femtosecond time-resolved studies using fluorescence depletion spectroscopy were performed on the vibrational relaxation; orientational relaxation and the intermolecular energy transfer of dye molecules in solutions under different conditions. The correlation of such ultrafast process with the system temperature and property of solvents is analyzed, which is useful for the further study about the ultrafast process of DNA, protein and other biological molecules, such as intra- and intermolecular electron, proton and energy transfer and photoisomerization.

The Fe^0 concentration and pH had optimal values during the decolorization of X-BR in Fe^0-anaerobic biological system. When Fe0 dose, initial pH value and X-BR concentration were 400 mg/L, 7 and 100 mg/L respectively, the decolorization rate of X-BR in the integrated system could reach up to 90% after 68 h reaction. Compared with pure Fe^0 and pure microorganism treatment systems, it could be improved about 40% under the same experimental conditions. In addition, the analysis result of UV-vis spectrogram indicated that Fe^0 could promote effectively biodegrading of anthraquinone dye X-BR and its intermediate products.

结果表明，在Fe^0-厌氧微生物体系中，Fe^0投加量和pH值均存在最适宜值，当两者分别控制在400mg/L和7，染料初始浓度和反应时间分别为100mg/L和68h时，该体系脱色率可达到90%以上；与相同反应条件下的纯Fe^0、纯厌氧微生物体系相比，该体系的脱色率提高近40%根据紫外可见光谱分析，Fe^0可有效促进厌氧微生物对X-BR及其中间产物的降解，实现完全脱色。
