Gongye shui chuli, 2010 就粉末活性炭和大孔树脂对苯酐酸水的脱色效果进行了研究。首先考察了活性炭种类、脱色时间、活性炭用量等因素对脱色效果的影响,结果表明在优化后的条件下其对苯酐酸水的脱色率仍难以达到90%。此后通过试验筛选了4种脱色用大孔树脂,发现SXD-11树脂具有较好的脱色效果。在实验条件下,流出液体积为5 BV时的酸水脱色率在95%以上,10 BV时的脱色率<85%。针对工业应用,最后在活性炭脱色基础上构建了与树脂脱色相联合的分步脱色法。该分步脱色法不仅保证了流出液体积20 BV时总的脱色率保持在91%以上 ...

Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT The design of nanoparticles confined in hollow N‐doped carbon structures is crucial for improving the oxygen reduction reaction (ORR) kinetics, yet achieving this remains a significant challenge. In this work, hollow porous nitrogen‐doped carbon encapsulated FeP/Fe2P (H‐FeP/Fe2P) were successfully constructed via a templating method combined ...

Gongye shui chuli, 2006 用还原脱色剂对水溶性偶氮染料进行光还原脱色降解，重点考察了还原脱色剂、辐射光以及染料浓度等对还原脱色反应的影响，并将脱色后的染色废水回用于棉织物染色中。结果表明，以适当比例的引发剂和促进剂组成的还原脱色剂具有较强的脱色降解能力，辐射光对染料的还原脱色反应具有明显的促进作用，染料浓度的提高不利于染料的脱色降解反应。脱色废水可以回用于棉织物的活性染料染色中，通过降低染色过程中氯化钠和碳酸钠的添加量，可使染色试样与自来水染色试样的总色差（DE*）<1.0。

Evaluating protected areas’ coverage of threats to terrestrial biodiversity
Conservation Biology, Volume 39, Issue 6, December 2025.Abstract Protected areas (PAs) are vital for biodiversity conservation and have expanded globally. However, increasing pressures on biodiversity make it difficult to achieve conservation goals. Using threat probability maps based on the International Union for Conservation of Nature Red List and the World Database of Protected Areas, we analyzed the ...

包埋固定化CK3脱色菌对偶氮染料Reactive Red 180的脱色特性 [PDF]
, 2009 采用改进的PVA-硼酸包埋法固定化CK3脱色菌,以偶氮染料CIReactive Red180为处理对象,采用批式工艺在缺氧条件下,系统考察了原水pH、外加碳源、盐度等因子对固定化CK3脱色菌脱色特性的影响,同时通过试验现象分析了不同进水条件下固定化凝胶小球强度的变化。结果表明,进水pH为碱性时脱色效果最好,但小球强度较差,向水中引入了大量有机物质,使废水中COD显著增大,进水pH为酸性时,有利于保持凝胶小球的强度,但脱色效果不如碱性条件;固定化CK3脱色菌对以葡萄糖为外加碳源的染料废水的脱色效果较好 ...

四川大学学报. 自然科学版, 2009 已分离鉴定的无色杆菌属（Achromobacter sp.）菌株MGT3对孔雀绿染料具有强脱色作用,对其产酶脱色能力进行初步研究表明,该菌株不需要孔雀绿作为底物即可产脱色酶,即脱色酶的产生不需要底物的诱导;其胞内和胞外都存在脱色能力强的脱色酶.产胞外脱色酶的条件优化结果显示培养基的组成对该菌株产胞外酶的能力有很大影响.采用单因素结合正交试验优化产酶培养基结果表明,培养基的最佳组成成分为0.5%蔗糖、2.5%尿素、0.0025%KH2PO4;该菌株在培养基初始pH为9、温度为35℃时产脱色酶效率高 ...
