Abstract: 研究了活性艳蓝X-BR上染白枫单板的影响因素和最佳染色工艺,采用7因素4水平正交染色试验,考察了染色温度、染液质量分数、促染剂用量、染色时间、固色剂用量、固色时间、体积比7个因素对上染率和表面色差的影响。采用直观分析和方差分析得出了影响上染率和表面色差的主要因素,并采用扫描电镜(SEM)观察染料分子在木材内的分布情况,以及X射线能谱分析(EDXA)染料分子的特征元素在木材中的含量。研究结果表明:染料质量分数和染色温度对上染率和表面色差影响较大。上染率最佳工艺方案为:温度60~65 ℃,质量分数0.5%,促染剂用量50 g/L,染色时间3.0 h,固色剂用量15 g/L,固色时间75 min,体积比1:15。表面色差最佳工艺方案为:温度50~55 ℃,质量分数3%,促染剂用量40 g/L,染色时间3.0 h,固色剂用量15 g/L,固色时间75 min,体积比1:40。SEM和EDXA结果表明染料分子团聚在木射线周围和分散在导管内,且染料分子的特征元素含量增加。
There are many advantages of dichlorotriazine reactive dye, such as strong reactivity, bright hues, and large number of active groups. The rapid forming radicals of dichlorotriazine reactive dye accelerate the nucleophilic reaction. Dyeing with dichlorotriazine reactive dye could save the time and reduce the temperature of dyeing and fixation, resulting in low processing cost and low energy consumption. In short, the processing efficiency is excellent. In order to enrich the color of interior and exterior dyeing, and expand the range of its application on wood, more effectively take advantage of the dichlorotriazine reactive dye was studied. In this work, the optimal dyeing process and its influencing factors of dyeing maple veneer with reactive brilliant blue X-BR was explored by means of orthogonal test. Research by visual and variance analysis, the dye-uptake and color difference in the surface were affected by several main factors, including dyeing temperature and dye concentration, dosage of dyeing agent, dyeing assistant, dyeing time, dosage of dye-fixing agent, fixation time, and volume ratio. The distribution and characteristics elements of the dye molecules in the wood were observed with SEM and analyzed through EDXA respectively. The results showed that the dye concentration and dyeing temperature have great impacts on dye-uptake and color difference in the surface. The optimal process of dye-uptake was:temperature 60-65 ℃, dye mass fraction 0.5%, dyeing agent 50 g/L, dyeing time 3.0 h, fixing agent 15 g/L, fixing time 75 min, ratio 1:15. The optimal process of color difference was:temperature 50-55 ℃, dye mass fraction 3.0%, dyeing agent 40 g/L, dyeing time 3.0 h, fixing agent 15 g/L, fixing time 75 min, ratio 1:40. SEM and EDXA results showed that the dye molecules aggregated around the wood rays and dispersed in the vessels, and the content of characteristic elements of the dye molecules were increased

环境工程学报 , 2011,
Abstract: 研究了废布料活性炭从水溶液中吸附2种典型染料(酸性蓝62和活性艳蓝KN-R)的吸附特性,从动力学角度探讨了吸附机理。结果表明,废布料活性炭对2种染料的平衡吸附量(qe)均随着初始浓度的增加而升高,相同条件下,qe的大小顺序为酸性蓝62>活性艳蓝KN-R。吸附过程符合准二级动力学模型,对于酸性蓝62,粒子内扩散过程是该吸附速率的控制步骤,但不是唯一的速率控制步骤,吸附速率同时还受粒子外部扩散过程的控制,而对于活性艳蓝KN-R,粒子内部扩散过程不是吸附速率的控制步骤。
论宋词中的“侧艳体”  [PDF]
岳珍?
天府新论 , 2003,
Abstract: “侧艳体”是宋词创作中的一种体式。“侧艳体”具有不同于一般爱情词、甚至一般的青楼楚馆词的特点。“侧艳体”的审美风格猥琐轻薄,因此,宋人在编集时习惯对这类作品另作处理。大概由于同样的原因,“侧艳体”仅见载于王灼的《碧鸡漫志》。“侧艳”本是音乐概念,由于王灼的误解,遂变为词的体式的概念,远离了本来的含义。

Abstract: A promising electrochemical sensor based on PANI/AgCl hybrid material has been developed. The organic/inorganic hybrid material has exhibited good electrocatalytic properties by cyclic voltammetry measurement and differential pulse voltammetry. The oxidation overpotential of dopamine decreased dramatically, and the oxidation peak current increased significantly at PANI/AgCl/GCE compared to those obtained at PANI/GCE, AgCl/GCE and bare GCE, corresponding to the synergistic effect between PANI and inorganic particle AgCl. Under the optimized conditions, the linear response in the concentration range of 0.7 to 6.0 μM for the selective determination dopamine on the PANI/AgCl/GCE is obtained with a detection limit of 5.4 × 10–8 M (S/N = 3) using differential pulse voltammetry. The results indicated that the modified electrode can be used to determine dopamine without the interference from ascorbic acid and ensure high sensitivity and good selectivity.

Abstract: A Ag/AgCl solid reference electrode was studied, which was characterised by simple structure, stable electrode potential and low temperature coefficient. A probe based on the solid reference electrode was also prepared. The suitability of the probe was investigated in 5% NaCl solution and vapour environment. The results showed that the solid reference electrode could fit the electrochemical measurements in both high resistance and low resistance media.
