氯酚

The significant induction of SOD and CAT suggested they might be used as potential biomarkers to indicate the stress of single compound and equitoxic binary mixtures of 2-chlorophenol and 2, 4-dichlorophenol in goldfish.

受试金鱼肝脏组织内抗氧化酶活性变化结果提示SOD和CAT较适于作为监测氯酚和二氯酚暴露金鱼体内应激性变化的有效生物标志物。

A sensitive spectrophotometric method for the determination of trace amounts of chlorine dioxide based on the fading reaction of chlorophenol red by chlorine dioxide has been developed in the alkaline solution.

在弱碱性条件下，二氧化氯(ClO2 )氧化氯酚红使其褪色，于 5 75nm波长处测定剩余氯酚红的吸光度，当用试剂空白参比时，吸光度的降低值与ClO2 的浓度呈直线关系，其它氧化剂在测定条件下无干扰，方法有较高的灵敏度和很好的选择性。

This complex reaction was phenolic electronic substitution reaction, so reaction rate was related with the positive electricity of pro-electronic reagent, as well as the form of aromatic hydrocarbons. Rates of chlorination of phenol and 2-monochlorophenol were faster in alkaline water than that in weak acid water, so 2,4-dichlorophenol and 2,4,6-trichlorophenol formation concentrations increased with the reaction time.

该复合反应属于酚类电子取代反应，反应速率与亲电子试剂的阳电性以及芳香烃的形式有关，碱性水环境中氯取代苯酚和2-一氯酚的速率要快于在弱酸性水环境；随着pH的升高，2，4-DCP和2，4，6-TCP的生成浓度也不断增加。

The experimental group(28 cases) was injected Tc-MDP 5mg/days by vein and received Diclofenac Diethylamine Emulgel drug .

对照组（26例）常规采用非甾体抗炎药物双氯酚酸治疗，治疗组（28例）在服用双氯酚酸的同时静注 Tc-MDP（5mg/d）。40d后获取两组静脉抗凝血（3ml），分离出红细胞与血浆。

The biodegrading effect of 2,4-Dichlorophenol from aqueous solution by immobilized Phanerochaete chrysosporium was studied and the feasibility of using immobilized Phanerochaete chrysosporium to treat the chlorophenols-contamination water was investigated.

研究固定化黄孢原毛平革菌对水溶液中2， 4-二氯酚(2， 4-DCP)的降解效果，探讨固定化黄孢原毛平革菌处理水溶液中氯酚类污染物的可行性。

Among the special nine pollutants, however, eight of them, including Hexachlorobenzene, N-Nitrosodi-N-propylamine, 3,3-dichlorobenzidine, 2,4,6-trichlorophenol, 2,3,4,5,6-pentachlorophenol, indeno (1,2,3-cd) pyrene, 4,4'-DDT and Heptachlor were in need of concern while another chemical: dibenzanthracene be of special concern. The sources of these chemicals were discussed and some control strategies were suggested based on the risk assessment.

结果表明，有18种有机污染物超过了USEPA的标准浓度要求，其中9种物质具有一定的生态风险，其中六氯苯、N-亚硝基二正丙胺、3，3'-二氯联苯胺、2，4，6-三氯酚、五氯酚、茚并(1，2，3-cd)芘、4，4'-滴滴涕、七氯在内的8种化合物具有一定的风险，而多环芳烃二苯并蒽需要引起更高警惕；在此基础上探讨了这些化合物的来源及作用，并提出了相应的防治建议。

TOC removal lags behind 4-chlorophenol removal in the ·OH-induced oxidative systems, indicating radiolytic technology alone is not efficient in terms of mineralization; the presence of O〓 and alkaline conditions facilitate the mineralization process.

羟基自由基氧化体系中TOC的去除滞后于4-氯酚的去除，说明单独使用辐射方法，氯酚的矿化率不高；氧气及碱性条件有利于体系中4-氯酚的矿化。

Pentachlorophenol is one of the most toxic organic pollutants and is difficult to be degraded among the chlorophenoxies.

五氯酚是氯酚族中最具毒性和最难降解的有机污染物，其废水的处理一直受人关注。

Pentachlorophenol is one of the most toxic organic pollutants that are difficult to degrade in chloropenoxies.

五氯酚是氯酚族中最具毒性和最难降解的有机污染物。

The effecting factors of the treatment of soil polluted by pentachlorophenol by Fenton reagent are determined by reading a large number of documentations.

通过查阅相关文献确定了Fenton试剂处理五氯酚的影响因子，并对各因子进行单因子分析，探讨了Fenton试剂的作用规律，确定了Fenton试剂法处理五氯酚的最佳处理条件。
