Veterinary Dermatology, Volume 34, Issue 4, Page 348-354, August 2023., 2023 Background – Glycerinated allergen extracts contain 50% glycerin, an excellent preservative. While glycerin is a recognised irritant in humans, the utility of glycerinated extracts for intradermal testing has not been validated in dogs. Hypothesis/Objective – To determine and compare the effects of glycerin on immediate cutaneous reactions to ...

Veterinary Dermatology, Volume 34, Issue 3, Page 222-234, June 2023., 2023 Background – Mycophenolate mofetil (MMF) is the prodrug of mycophenolic acid (MPA) which acts as an immunosuppressive agent. During the biotransformation of MMF to MPA, additional metabolites including MPA phenol glucuronide (MPAG), MPA acyl glucuronide (AcMPAG) and MPA phenol glucoside (MPG) are formed.

Gongye shui chuli, 2020 利用介质阻挡放电低温等离子体技术实现了废水中Cr（Ⅵ）和苯酚的同步去除。研究表明，低温等离子体对苯酚和Cr（Ⅵ）有较强的去除能力。其中·OH在苯酚氧化降解过程中起主要作用，而·OH的消耗能够明显促进Cr（Ⅵ）的还原。分析了苯酚和Cr（Ⅵ）共存条件下污染物的去除效果，发现去除过程中苯酚和Cr（Ⅵ）存在协同作用：苯酚能够与·OH发生反应，增加还原性·H含量，促进Cr（Ⅵ）的还原；Cr（Ⅵ）通过消耗还原性物质，间接增加了与苯酚反应的·OH含量，促进苯酚的降解。

Gongye shui chuli, 2020 对比了SBR与SBR-HASP系统对含苯酚废水的去除效果。由于腐殖活性污泥的作用，SBR-HASP系统对苯酚的去除效能要高于传统的SBR系统。对高浓度含苯酚废水处理工艺进行优化，与蛋白胨、苯酚作碳源相比，蛋白胨、甲醇和苯酚为碳源时对污泥有良好的驯化效果。

Gongye shui chuli, 2017 通过富集驯化获得具有高效降解苯酚能力的苯酚降解菌群PDBC-1，对菌群降解苯酚的性能及影响因素进行了分析。结果表明，红球菌属细菌是该菌群中的优势菌种。在初始苯酚质量浓度低于1 200mg/L 时，菌群能够在72 h 内完全降解苯酚，但在更高苯酚浓度下，苯酚对菌群生长造成明显抑制，苯酚降解能力显著下降。该菌群降解苯酚的适宜盐度为0~5%，温度为25~40℃，pH 为7.0~8.0。

Gongye shui chuli, 2015 采用介质阻挡放电等离子体/微曝气技术协同处理苯酚废水,考察放电电压、放电时间、溶液初始浓度及曝气量对苯酚处理效果的影响。研究结果表明:苯酚降解率随放电时间增加、苯酚初始浓度减小而提高;曝气量为150 mL/min时,苯酚降解率为51.8%。采用介质阻挡放电等离子体/微曝气协同工艺处理苯酚废水,与单独使用介质阻挡放电等离子体工艺相比,苯酚降解率提高了15%~20.4%。

Gongye shui chuli, 2007 苯酚厌氧降解微生物可分为产甲烷聚生体细菌、硫酸盐还原细菌、反硝化细菌及金属还原细菌。苯酚在常温厌氧条件下以苯甲酸为中间产物进行降解，但是苯酚向苯甲酸的转化过程以及高温条件下苯酚降解机理仍处于争论阶段。苯酚羧化是反应的限速环节。针对高浓度苯酚对微生物活性的抑制问题，目前采用的主要方法有改变温度、物理吸附、回流稀释以及投加共代谢基质。最后提出了厌氧降解含酚废水的发展前景和研究方向。

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Photocatalytic molecular oxygen (O2) activation provides a sustainable approach to produce singlet oxygen (1O2) for organic contaminants detoxification. However, the charge carriers‐involved pathway usually suffers from unsatisfactory 1O2 production efficiency owing to energy loss caused by photogenerated hole‐mediated superoxide species (•O2−

Gongye shui chuli, 2011 通过对粉煤灰进行改性，研究其对模拟含酚废水中苯酚去除效果。探讨了pH、吸附时间、投加量、吸附温度及水样中苯酚初始浓度对粉煤灰去除苯酚效果的影响。实验表明，选用碱改性的粉煤灰，投加15 g/L 处理苯酚质量浓度30.0 mg/L 的模拟含酚废水，当吸附时间为30 min，pH 为6~7 时，对苯酚去除率达98%，吸附等温线拟合结果表明，该吸附过程符合Freundlich 公式。改性粉煤灰可作为废水去除苯酚的吸附剂。
