Removal of Dimethylamine by Ozone Combined with Hydrogen Peroxide (O₃/H₂O₂)

International Conference on Energy and Environment Technology (2009)

Lei Yang Zhonglin Chen Xiaowei Liu Xu Zhai Jimin Shen

Ozonation of dimethylamine (DMA), the most direct and common precursor of high carcinogenic disinfection by-product N -nitrosodimethylamine (NDMA), in aqueous solutions and in the presence of H ₂ O ₂ was studied at ozone doses of 1.8mg/L. The removal ratio of DMA increases from 46.7% to 77.1% with the dosage of H ₂ O ₂ increasing from 0 to 1mM, and the removal rate can be improved by increasing pH. According to the results of H ₂ O ₂ addition time experiments, hydroxyl radicals might play important roles in the destruction of DMA during combined oxidation process. With the treatment of O ₃ /H ₂ O ₂ for 24h (containing 0.5mM DMA), the yield of NDMA formation was below our detection limit (0.1μ:g/L) and the yield of NDMA formation after chloramination (24h) of DMA containing water could be reduced by 90%.

Determination of Nitrobenzene in Sediment Using Ultrasonic Extraction and Gas Chromatograph Method

Zhonglin Chen Yue Ben

An ultrasonic extraction and gas chromatograph method were used to determine the nitrobenzene concentration in sediment.Affecting factors such as the proportion and dosage of the extractants,the ultrasonic extraction time and the dosage of salting-out agent were investigated.Using this method,the average recovery of nitrobenzene by dissolving sediment in distilled water and the Songhua River water are 91.6%-97.4% and 83.4%,respectively; and the relative standard deviations(RSD) are(1.9)%-4.4% and 7.1%,respectively.The method is simple and rapid in operation.It takes only 90 min for a whole detection process including sample pretreatment.

Selective Catalytic Reduction of NO with NH3 over Wire-Mesh Honeycomb Supported V2O5 -MoO3/TiO2/Al2O3 Catalyst

Xu Zhai Zhonglin Chen Jie Yao He Wang Junsheng Li

A novel V ₂ O ₅ -MoO ₃ /TiO ₂ /Al ₂ O ₃ metal wire-mesh-honeycomb catalyst prepared by electrophoretic deposition (EPD) was investigated for the selective catalytic reduction (SCR) of NO with NH ₃ . The effects of reaction temperature, space velocity and NH ₃ /NO ratio on the SCR activity were evaluated. The experimental results show that V ₂ O ₅ -MoO ₃ /TiO ₂ /Al ₂ O ₃ catalyst can achieve satisfied NO removal effect at 350degC; the increase of the space velocity will make NO conversion ratio reduce, except 400degC. NH ₃ /NO ratio has a little influence on NO removal efficiency, which raises slowly with the increasing NH ₃ /NO ratio. At the same time, body structure and surface character of catalyst prepared were characterized by XRD, SEM and XPS. Combining characterization with the results of activity test, the relation between catalyst structure and catalysis performance was analyzed. The results of characterization show that the active component is uniformly distributed on the catalyst carrier as a single layer and high SCR activity is attributed to the strong interaction between TiO ₂ and V ₂ O ₅ .

Continuous Flow Experimental Study on Ozonation of Ibuprofen Catalyzed by Silicate-Based Microfiltration Membrane

Water (2023)

Weiqiang Wang Zhonglin Chen Jimin Shen Pengwei Yan Wang Bingyuan

In the treatment of drinking water, the ibuprofen (IBP) disinfection by-products, toxicity, and its impact on drinking water safety have caused widespread attention in domestic and overseas research areas. We studied the removal efficiency of IBP under the following conditions: combination of good catalytic activity of a silicate-based microfiltration membrane with the strong oxidizing ability of ozone in the continuous flow experiment mode and various influencing factors. This research revealed that with the increase of pH and hydraulic retention time, the removal efficiency of IBP exhibited an increasing trend; with the increase of alkalinity and humic acid concentration in water, the removal efficiency of IBP was obviously inhibited. Free radical inhibitors and electron spin resonance (ESR) analysis demonstrated that hydroxyl radical (∙OH) is an important active species during the reaction of ozone-catalyzed IBP with the silicate-based microfiltration membrane.

THM and HAA Formation from Sequential Use Ozone and Monochloramine to Disinfection in the Presence of Tannic Acid

International Conference on Energy and Environment Technology (2009)

Shuqing Zhao Zhonglin Chen Lei Yang Xu Zhai An Li

Tannic acid, as a surroguate of natural organic matter (NOM), were used as model compound. A study was conducted to evaluate the main disinfection byproducts of sequential use ozone and monochloramine to disinfection in the presence of tannic acid. Results of Disinfection byproduct formation potential show that the main disinfection byproduct include TCM (trichloromethane) and DCAA(dichloroacetic acid). Smaller anounts of TCAA(trichloroacetic acid) were also found. The production of TCM and DCAA increase significantly with the increase of disinfectant dosage(ozone and monochloramine)and temperature. From pH 7-8, more disinfectant byproducts are produced.
