Dose Response and FWHM Properties of Dyed Poly Vinyl Alcohol-Irradiated with Gamma-Rays

Open Journal of Polymer Chemistry 2013年第2期3卷 39-42页

The effects of gamma irradiation on absorption properties of Carbol Fuchsin (CF) with crystal violet dyed Poly Vinyl Alcohol (PVA) blended for possible use in dosimetry and measurement of radiation dose in gamma rays have been studied using UV-Visible spectrophotometer method. The films were irradiated to accumulated doses from (10 to 70) Gy using Co60 gamma ray source at a constant dose rate. The absorption spectra were measured using UV-Visible spectrophotometer in the wave length range (200 to 900) nm, resulting in a decrease of the absorbance at 560 nm band peak with increasing dose. Regarding to the IR transmittance it’s appearing that for the samples with crystal violet the band at 1716 divided two small bands which become obvious for the irradiated one which indicate also the effect of gamma doses. In this study, the less Full Width at Half Maximum (FWHM), the better is the dosimeter. The FWHM due to sharpness in the band peak and this is useful for determine the fine dosimeter.

Microfluidic Behavior of Ternary Mixed Carrier Solvents Based on the Tube Radial Distribution in Triple-Branched Microchannels in a Microchip

Journal of Analytical Sciences, Methods and Instrumentation 2012年第2期2卷 49-53页

作者： Naoya Jinno Masahiko Hashimoto Kazuhiko Tsukagoshi Department of Chemical Engineering and Materials Science Faculty of Science and Engineering Doshisha University Kyotanabe Japan Department of Chemical Engineering and Materials Science Faculty of Science and Engineering Doshisha University Kyotanabe Japan.

Microfluidic behavior of ternary mixed carrier solvents of water-acetonitrile-ethyl acetate (2:3:1 volume ratio) was examined by use of a microchip incorporating microchannels in which one wide channel was separated into three narrow channels, i.e., triple-branched microchannels. When the ternary carrier solution containing the fluorescent dyes, hydrophobic perylene (blue) and relatively hydrophilic Eosin Y (green), was fed into the wide channel under laminar flow conditions, the carrier solvent molecules or fluorescence dyes were radially distributed in the channel, forming inner (organic solvent-rich major;blue) and outer (water-rich minor;green) phases in the wide channel. And then, in the narrow channels, perylene molecules mostly appeared to flow through the center narrow channel and Eosin Y, which is distributed in the outer phases in the wide channel, flowed through the both side narrow channels. A metal ion, Cu(II) as a model, dissolved in the ternary mixed carrier solution was also examined. The Cu(II) showed fluidic behavior, transferring from the homogeneous carrier solution to the water-rich solution in the side narrow channels through the triple-branched microchannels.

Advanced Oxidation Processes for Treatment of Textile and Dye Wastewater: A Review

International Conference on Environmental Science and Development（ICESD 2011）

作者： Shashank Singh Kalra Satyam Mohan Alok Sinha Gurdeep Singh Department of Environmental Science and Engineering Indian School of Mines Dhanbad India

Textile wastewater containing dyes are difficult to treat by conventional biological processes as most of the dyes are non-biodegradable and are toxic to the microorganisms. These dyes can be easily treated if the conventional treatment methods are incorporated with the advanced oxidation process which can break the complex structure of the dye and make it more amenable to bio-degradation. This paper reviews different Advanced Oxidation Processes （AOPs） like ozonation, hydrogen peroxide, UV radiation and their combination for comparison of treatment efficiencies for remediation of textile wastewater. The paper reveals that the treatment efficiencies of various options depends on the characteristics of the wastewater to be treated.

针对进出口贸易类企业在多厂家、多品种检测中遇到的需要快速鉴定纺织品面料中是否含有禁用偶氮染料的问题,开发了一种定性筛选纺织面料的测试方法,并对直接、酸性、活性、靛蓝、硫化、还原6类染料染色后的纺织面料进行禁用偶氮染料的24种芳香胺检测,纺织面料为纯棉和尼龙材质。此方法大大减少了对色谱仪器的依赖,所用试剂少,检测时间少,检测效率高,检测成本低。

关键词：禁用偶氮染料芳香胺纺织品 Banned Azo dyes Aromatic Amines Textiles
