| 4. | Photooxidation process of volatile organic compounds and gas / particle partitioning process of their photooxidation products are very important on formation of secondary organic aerosols 摘要挥发性有机化合物的光氧化过程和光氧化产物的气态粒子态均分过程是二次有机气溶胶形成的重要原因。 |
| 5. | Photooxidation was one of the main degradation approaches of pesticides in environment . photo - stability had a direct influence on the effectiveness and persistent of pesticides . so the photooxidative degradation of triazophos in water was studied in this paper 光氧化降解是农药施用后在环境中的主要降解途径,农药光稳定性对农药的药效持久性及在环境中的残留消失动态具有直接影响。 |
| 6. | Chemical mechanism on formation of secondary organic aerosols involves in photooxidation process of volatile organic compounds and subsequent chemical reaction , which directly lead to increase of ozone concentration and to formation of secondary organic aerosol in troposphere 二次有机气溶胶形成的化学机理主要涉及到挥发性有机化合物的光氧化过程及其一系列的后续反应,它们导致了对流层中臭氧浓度的增加和二次有机气溶胶的形成。 |
| 7. | ( 6 ) the treatment of wastewater containing triazophos using uv , uv - h2o2 , uv - fenton ( fe2 + ) , uv - fenton ( fe3 + ) were tested under the conditions with and without aerating air . the result showed that photooxidation can improve the biodegradability of this type of water ; the removal rate of cod improved markedly by aerating air . both uv - fenton ( fe2 + ) and uv - fenton ( fe3 + ) the removal rate of cod was reached above 80 % after treating 120 minutes , distinctly higher than uvand uv / h2o2 ( 6 )在直接光氧化和向水体充入空气的光氧化条件下进行了uv 、 uv - h _ 2o _ 2 、 uv - fenton 、 uv -类fenton四种工艺处理含三唑磷废水的实验研究,结果表明:光氧化处理改善了含三唑磷水样的可生化性;曝气使处理效果显著提高; uv - fenton 、 uv -类fenton两种工艺的处理效果较好,处理效果达到80左右,远高于另外两种工艺的处理效果。 |
| 8. | Factors effecting the degradation rate , including types of light sources , photooxidation catalyzers and sensitizers , the ph value of water and the component of humus were investigated in the experiment , and the treatment of wastewater containing triazophos using uv - fenton was also studied in this paper 为此本文进行了三唑磷在水体中光降解的实验研究,考察了光源、光催化剂及光敏剂、水体ph值、腐殖质成分等因素对三唑磷光降解的影响,并对uv - fenton处理三唑磷废水进行了研究。 |
| 9. | Carotenoids can make chla return from excited state to ground state by direct or un - direct quenching , in order to prevent algae from photooxidation . on the other hand , it was indicated that polysaccharides have functions in resisting uv . spirulina plalensis can accumulate both cellular and extracellular polysaccharides during uv treatment , it showed highest uv resistant ability ; nanochloropsis sp also can accumulate cellular polysaccharides , while extracellular polysaccharides reduced ; the cellular polysaccharides content of phaeocystis globosa scherffel decreased and extracellular polysaccharides content did not increased markedly , showing lowest uv resistant ability 钝顶螺旋藻和微绿球藻中在较低的uv辐射强度下类胡萝卜素含量升高,而叶绿素a保持相对稳定,说明类胡萝卜素可能对藻类起到一定保护作用,可能通过直接的或间接的方式猝灭激发态的叶绿素,来保障光合作用的进行;本实验发现多糖的累积和分泌与藻体的抗uv能力有相关,钝顶螺旋藻的细胞内和细胞外多糖分泌旺盛,其抗uv能力最强;微绿球藻体内能积累多糖,而胞外多糖分泌减少;球形棕囊藻的胞内多糖含量减少,胞外多糖含量增加也不明显,其抗uv能力最弱。 |
