Well-aligned carbon nanotubes coated with titania (TiO2) were prepared by atmospheric pressure chemical vapor deposition (APCVD),and the sequential experiments including carbon nano- tubes preparation,air-oxidation purification and tita- nia nanoparticles coating were performed at different temperatures in the same reactor. Scanning electron microscopy (SEM),transmission electron microscope (TEM),X-ray diffraction patterns (XRD),and energy- dispersive X-ray spectra (EDX) demonstrated the well-aligned nanotubes and TiO2 nanoparticles in close proximity and the average diameter of TiO2 nanoparticles was 11.5 nm.

Norfloxacin（NOR）, an ionizable antibiotic frequently used in the aquaculture industry, has aroused public concern due to its persistence, bacterial resistance, and environmental ***, we investigated the photolysis of different species of NOR and the impact of a ubiquitous component of natural water — dissolved organic matter（DOM）, which has a special photochemical activity and normally acts as a sensitizer or inhibiter in the photolysis of diverse organics; furthermore, scavenging experiments combined with electron paramagnetic resonance（EPR） were performed to evaluate the transformation of NOR in water. The results demonstated that NOR underwent direct photolysis and self-sensitized photolysis via hydroxyl radical（U OH） and singlet oxygen（1O2） based on the scavenging experiments. In addition, DOM was found to influence the photolysis of different NOR species, and its impact was related to the concentration of DOM and type of NOR species. Photolysis of cationic NOR was photosensitized by DOM at low concentration, while zwitterionic and anionic NOR were photoinhibited by DOM, where quenching of U OH predominated according to EPR experiments, accompanied by possible participation of excited triplet-state NOR and1O2. Photo-intermediate identification of different NOR species in solutions with/without DOM indicated that NOR underwent different photodegradation pathways including dechlorination, cleavage of the piperazine side chain and photooxidation, and DOM had little impact on the distribution but influenced the concentration evolution of photolysis intermediates. The results implied that for accurate ecological risk assessment of emerging ionizable pollutants, the impact of DOM on the environmental photochemical behavior of all dissociated species should not be ignored.

有机溴代苯酚类污染物在水体中普遍存在,尤其在海洋环境中,除人为污染源外,它还存在广泛的天然来源.以2,4,6-三溴苯酚为模型化合物,以氙灯(λ>290 nm)作为模拟太阳光源,研究了海水中溴代苯酚的光化学过程,并系统考察了溴代苯酚初始浓度、Cl^-、Fe(Ⅲ)和pH值等环境因素的影响.实验结果表明,在海水中,2,4,6-三溴苯酚能够快速发生光化学反应,通过产物分析发现其主要产物为通过光致脱溴氯代过程产生的2,4-二溴-6-氯苯酚,并且该产物随2,4,6-三溴苯酚初始浓度、Cl^-浓度、Fe(Ⅲ)浓度的增大及溶液pH值的降低而增加.以明亮发光杆菌为受试生物的毒理学实验表明,2,4,6-三溴苯酚在海水中光化学的前期,系统的毒性效应增强,而毒性的增加可能主要由光致氯代过程导致.

研究白洋淀表层水(白洋淀原水)、无机盐培养基、无机盐培养基强化的白洋淀原水中双酚A在白腐真菌作用下的生物降解规律,同时考察了细菌及pH等因素对降解率的影响。实验结果表明,白洋淀原水中双酚A在白腐真菌作用下的降解率很高,甚至高于最适营养条件(无机盐培养基)下双酚A的降解率,在6d达到完全降解,但是无机盐培养基强化的白洋淀原水抑制了白腐真菌对双酚A的降解;当细菌存在时,白腐真菌与细菌对碳源和能源等形成了竞争关系,抑制了白腐真菌的生长,不利于白腐真菌对双酚A的降解;无机盐培养基强化的白洋淀原水在初始pH=6.00时双酚A的降解率高于初始pH=7.00时双酚A的降解率。通过气相色谱/质谱(GC/MS)分析,白腐真菌降解双酚A的中间产物包括2-对羟苯基-2-酮基-1-乙醇、2-羟基苯乙酸和丙二酸等小分子酸。
