Restoration of the red colour of photo-bleached carthamine in calcium-alginate gel membranes

The restoration of the red colour of carthamine (photo-bleached in polymeric heterosaccharide gels) was investigated using sodium salts, potassium salts, and alkali. Ca-alginate gel was stained with carthamine, and the red-dish membranes were exposed to fluorescent light for 2·5, 4·0 and 20 h (at 28°C). The resulting orange-yellow gel membranes were treated with Na- or K-citrate solution and the restoration of the red colouration was followed spectrophoto-metrically. The results indicate that the red colour of carthamine can be retained within the gel membranes, while yellow-coloured compounds were removed and/or transformed by the alkaline salt solutions.

烧结法赤泥-沥青粉固化剂稳定粉土的路用性能研究

为解决黄河冲积平原地区粉土粘聚力低、水稳定性差等工程应用问题,采用烧结法赤泥和基质沥青为主材制备粉土固化剂(RAC)对粉土进行综合稳定。按5%水泥优选掺量并附加0,2,4,6,8% RAC成型稳定粉土试件,经过标准养护、浸水软化、循环加热、低温冻融、高温自愈等特定试验条件后,进行3d、7d和28d龄期的抗压强度与压缩模量试验,对比分析不同掺量RAC稳定粉土路用性能的变化规律。采用扫描电镜(SEM)分别观察粉土、水泥稳定粉土和RAC稳定粉土的微观结构形貌和孔隙特征,进而探讨固化稳定机理。结合实体工程的应用实践对RAC稳定粉土的路用性能进行测试分析与验证。结果表明：与单掺水泥相比,RAC稳定粉土具有良好的力学性能,2,4,6,8%RAC稳定粉土标准养护3d强度分别提高110%,146%,156%,161%,28d龄期浸水强度损失率均小于20%;当RAC掺量高于4%时,循环加热5次以上可使稳定粉土的强度增长超过140%,低温冻融强度损失率小于15%;试件加载至90%极限荷载,循环加热5次后,2,4,6,8%RAC稳定粉土强度变化率分别是-8.3%,-2.3%,+8.0%,+12.9%。SEM图像显示RAC稳定使粉土形成密实的胶结凝聚体和均匀分布的孔径小于1μm非连通微孔结构,有利于稳定粉土水稳定性和抗冻性的提高;高温条件下沥青组分发生湿润粘结包裹粉土颗粒及水化产物,同时加速扩散填充内部孔隙和微裂缝,实现土体的损伤修复和结构补强。实体工程中RAC稳定粉土结构层取芯测试抗压强度为1.7MPa,压缩模量为1360MPa,路面弯沉为18~23(0.01mm),未出现裂缝、坑槽、松散等损坏现象。     

A new application of Hydroxyapatite extracted from dromedary bone: Adsorptive removal of Congo red from aqueous solution

The aim of this paper is to evaluate the efficiency of the natural hydroxyapatite powder for anionic dye (Congo red) elimination from water and optimization of adsorption process parameters that are contact time (0-360 min), solution pH (4-9), initial dye concentration (400-2400 mg/l), and adsorbent dosage (0.4-20 g/l). Natural hydroxyapatite with high surface area was prepared from animal agriculture waste dromedary bone. X-ray diffraction, transmission electron microscopy, transform infrared spectroscopy, and elemental analysis characterizations of the powder prepared show a hexagonal structure, the irregular form of hydroxyapatite and presence of other elements as trace element. The results of adsorption tests demonstrated the high efficiency of natural hydroxyapatite for removal of Congo red from water solution whose maximum experimental capacity adsorption of Congo red by natural hydroxyapatite is 900 mg/g at pH 4.5, equilibrium time 240 min and adsorbent dosage 2 g/l. According to the correlation coefficient value, the pseudo-second order kinetic model identified the sorption mechanism of pollutant used on natural hydroxyapatite. The Freundlich isotherm is the best representative theoretical model of the dye molecules’ adsorption on the natural hydroxyapatite support.

Decolorization of reactive brilliant red X-3B by heterogeneous photo-Fenton reaction using an Fe–Ce bimetal catalyst

Decolorization of reactive brilliant red X-3B was studied by using an Fe–Ce oxide hydrate as the heterogeneous catalyst in the presence of H₂O₂ and UV. The decolorization rate was in the order of UV–Fe–Ce–H₂O₂ > UV–Fe³⁺–H₂O₂ > UV–H₂O₂ > UV–Fe–Ce ≥ Fe–Ce–H₂O₂ > Fe–Ce. Under the conditions of 34 mg l⁻¹ H₂O₂, 0.500 g l⁻¹ Fe–Ce, 36 W UV and pH 3.0, 100 mg l⁻¹ X-3B could be decolorized at efficiency of more than 99% within 30 min. The maximum dissolved Fe during the reaction was 1 mg l⁻¹. From the fact that the decolorization rate of the UV–Fe–Ce–H₂O₂ system was significantly higher than that of the UV–Fe³⁺–H₂O₂ system at Fe³⁺ = 1 mg l⁻¹, it is clear that the Fe–Ce functioned mainly as an efficient heterogeneous catalyst. UV–vis, its second derivative spectra, and ion chromatography (IC) were employed to investigate the degradation pathway. Fast degradation after adsorption of X-3B is the dominant mechanism in the heterogeneous catalytic oxidation system. The first degradation step is the breaking down of azo and CN bonds, resulting in the formation of the aniline- and phenol-like compounds. Then, the breaking down of the triazine structure occurred together with the transformation of naphthalene rings to multi-substituted benzene, and the cutting off of sulphonic groups from the naphthalene rings. The last step includes further decomposition of the aniline structure and partial mineralization of X-3B.
