Photo-degradation mechanism of Cationic Red X-GRL in the presence and absence of oxygen(氧在阳离子红染料光脱色中的作用机理研究)

Zhejiang Daxue xuebao. Lixue ban, 2003
以阳离子红X-GRL染料为模型污染物,研究了反应时间、气相氧气流量和水中是否存在溶解氧(DO)等条件对阳离子红X-GRL光降解脱色效果的影响.在缺氧条件下,阳离子红X-GRL染料的光降解脱色效果较差,脱色率仅为9.1%,染料的光降解脱色以光直接降解脱色为主,·OH脱色次之.在有氧条件下,阳离子红X-GRL染料的光降解脱色效果得到显著提高,脱色率由缺氧时的9.1%分别提高到氧气流量为40 L·h-1的27.6%和100L·h-1的38.8%.脱色率的提高主要归因于DO和气相氧气在184.9 ...

3种脱色剂应用于大豆油脱色的效果Decolorization effect of three decolorants on soybean oil WANG Hongping, SUN Rifei, HE Lijun, MA Li,

Zhongguo youzhi
旨在为大豆油精炼中脱色剂的应用提供参考，以大豆碱炼油和3种常用脱色剂活性白土、凹凸棒土、中性膨润土为原料，考察了3种脱色剂对大豆油的脱色、脱皂和脱磷脂能力。结果表明：活性白土、凹凸棒土、中性膨润土添加量超过2%后，脱色率上升速率变慢；脱色剂添加量为3%时，活性白土、凹凸棒土、中性膨润土脱色率分别为92.1%、86.9%、90.7%；大豆碱炼油在426、450、479、665 nm波长处有吸收峰，可通过油样在上述4个波长处吸光度的变化来考察脱色剂的脱色能力;脱色剂添加量为1%时，活性白土、凹凸棒土 ...

复合铝絮凝剂的制备及其脱色性能研究

Gongye shui chuli, 2007
以三氯化铝和有机高分子PGA为原料,制备了复合絮凝剂CPAC,并探讨了该种絮凝剂对模拟染料废水的脱色作用。研究表明,在同等铝盐投量的情况下,相对于PAC而言,CPAC脱色效率明显提高,且脱色率随PGA与铝盐的质量比(O/A)增高而上升。以活性艳红K-2BP染料为例,铝盐投加质量浓度6.8mg/L时,PAC脱色率75.5%,CPAC(O/A=0.05)脱色率为81%,CPAC(O/A=0.1)脱色率为86%。3种染料中,CPAC对分散黄G的脱色效果最好,铝盐投加质量浓度为3.3mg/L时脱色率达98%。
