酸性橙

PMN has a function of oxidation and adsorption under acidic conditions, such as Gentian Purple, Methylene Blue, Conga Red, Rhodamine B and Methyl Orange. PMN can oxidize diversiform dyes (pH＜4. 5). The increasing of concentration on Mn and wastewater UV-Vis spectra after contact can prove it.

PMN在酸性条件下（pH＜4.5）可氧化多种染料，如龙胆紫、亚甲基蓝、刚果红、罗丹明B和甲基橙等，通过测定体系Mn的生成量和模拟废水脱色后的紫外可见吸收曲线可有力证明上述观点。

The resultshows the extent to which the four dye fade due to be oxided from big to small is Acid OrangeⅡ＞Neutral Red＞Fuchsin Basic＞Acid OrangeⅡ.

The photocatalytic degradation property of ZnM2O4 (M=Cr, Mn, Fe) nanoparticles was investigated by using methyl orange, acid red B and reactive red K-2G as model pollutants under the irradiation of a mercury-vapor lamp (λ＞400 nm) or sunlight. The degradation rates of the above three dyes by ZnM2O4(M=Cr, Mn, Fe) are over 80％, 57％ and 39％, respectively within 2 h. It is found that ZnM2O4 (M=Cr, Mn, Fe)has a novel photocatalytic behavior for dyes under visible light irradiation.

The SERS of various concentration of Reactive Red, Acid Red, Acid Black, Direct sol orange and Calcon Carboxylic Acid adsorbed on silver colloid are studied by micro-Raman spectrometer. It has been found that the SERS intensity of absorbed molecules is mainly from the nearest molecule layer to the surface of silver colloid. That is, SERS has its single layer saturation effect. 2. The technique of direct deposition of silver colloid on a Kaolinite surface is first described.

以银溶胶作基底，利用显微拉曼光谱仪对不同浓度的活性艳红、酸性红、酸性黑、直接耐晒橙四种染料和钙羧酸指示剂的表面增强拉曼光谱进行了研究，结果表明，由于表面增强拉曼散射具有单分子层饱和效应和银溶胶系统对荧光的猝灭率很高，能吸附染料分子并增强拉曼散射的强度，且吸附分子的表面增强拉曼散射的强度，主要是由于最靠近银溶胶的一层分子的增强，而第一层以外的分子贡献很小。

The SERS of Reactive Red, Acid Red, Acid Black, Direct sol orange, chlorsulfuron, atrazine and carboxin adsorbed on Kaolinte then covered with silver colloid are studied by micro-Raman spectrometer.
