Optimization of parameters on photocatalytic degradation of chloramphenicol using TiO_2 as photocatalyist by response surface methodology

引用

Journal of Environmental Sciences 2010年第8期22卷 1281-1289页

作者： Junwei Zhang Dafang Fu Yunda Xu Cuiyun Liu department of Municipal engineering Southeast University Nanjing 210096 China Nanjing engineering Research centre for Water Treatment and ecological Restoration Nanjing 210013 China

The experimental design methodology was applied for modeling and optimizing the operation parameters on photocatalytic degradation of chloramphenicol （CAP） using TiO 2 as photocatalyst in a photoreactor. Three experimental parameters （including pH, TiO 2 concentration and CAP initial concentration） were adopted to obtain the preliminary information. The multivariate experimental design was employed to establish a quadratic model as a functional relationship between the degradation rate of CAP and three experimental parameters. The interaction effects and optimal parameters were obtained by using Design Expert software. The optimal values of the operation parameters under the related constraint conditions were found at pH 6.4, TiO 2 concentration of 0.94 g/L and CAP initial concentration of 19.97 mg/L, respectively. The degradation rate of CAP approached 85.97% under optimal conditions. The regression analysis with R 2 value of 0.9519 had a good agreement between the experimental results and the predictive values. In addition, pH and TiO 2 concentration had a significant influence on the degradation rate of CAP.

Estimation of carbon sequestration in reclaimed coalmine degraded land dominated by Albizia lebbeck, Dalbergia sissoo and Bambusa arundinacea plantation： a case study from Jharia Coalfields, India

引用

international Journal of Coal Science & Technology 2016年第2期3卷 246-266页

作者： Rimi Das Subodh Kumar Maiti ecological Restoration Laboratory Department of Environmental Science and Engineering (Centre of Mining Environment) Indian School of Mines Dhanbad Jharkhand 826 004 India

Reclaimed mined lands provide an excellent opportunity to sequester carbon and combat global warming. Carbon sequestration on reclaimed sites depend on age of reclamation, composition of species, geomining conditions （soil characteristics） and prevailing climate. The aims of the present study were to calculate carbon （C）--stock of biomass of 4 years old plantation （dominated by Albizia lebbeck, Dalbergia sissoo and Bambusa arundinacea）, understorey vegetation and litter, soil organic carbon in reclaimed minesoil （RMS） and compare with reference forest site. Allometric equation was used for the estimation of biomass C stock and found 13.0 Mg C ha i （A lebbeck 7.8 Mg C ha-I, D sissoo 3.5 Mg C ha-l and B. arundincea 1.2 Mg C ha-l）, while stock of understorey vegetation was 0.98 Mg C ha-~. In RMS, C stock was 16.3 Mg C ha-1, out of which inorganic C contributed 1.7 g kg-l （8 % of total soil C）, Coal C 8.7 g kg^-1 （43 % of total soil C） and biogenic C 9.8 g kg^-1 （49 % of total soil C）. Total C stock in reclaimed site was calculated as 30.3 Mg C ha^-1（equivalent to 111 Mg CO2 ha-b. The study concluded that （i） coal C is responsible for overestimation of C stock in RMS （ii） Maximun C stock stored in aboveground biomass component and （iii） reclaimed mined lands will take approximately 17 years to reach the level of C stock of reference forest site in dry tropical climate.

Effect of manganese sulfide on the precipitation behavior of tin in steel

引用

international Journal of Minerals,Metallurgy and Materials 2014年第7期21卷 654-659页

作者： Gui-lin Sun Bo Song Ling-zhi Yang Su-fen Tao Yong Yang State Key Laboratory of Advanced Metallurgy University of Science and Technology Beijing School of Metallurgical and ecological engineering University of Science and Technology Beijing department of Metallurgical Technology

Tramp elements such as tin are considered harmful to steel because of hot brittleness they induce at high temperatures. Because tramp elements retained in steel scrap will be enriched in new steel due to the difficultly of their removal, studies on the precipitation behavior of tin are essential. In this study, the effects of different inclusions on the precipitation behavior of tin in steel were studied. The results show that the tin-rich phase precipitates at austenite grain boundaries in an Fe-5%Sn alloy without MnS precipitates, whereas Sn precipitates at the boundaries of MnS inclusions in steel that contains MnS precipitates. MnS is more effective than silicon dioxide or aluminum oxide as a nucleation site for the precipitation of the tin phase, which is consistent with the disregistry between the lattice parameters of the tin phase and those of the inclusions.

Effect of humic acid and metal ions on the debromination of BDE209 by nZVM prepared from steel pickling waste liquor

引用

Frontiers of Environmental Science & engineering 2015年第5期9卷 879-887页

作者： Yuling CAI School of Chemistry and Environment South China Normal University Guangzhou 510006 China Guangdong Technology Research centre for ecological Management and Remediation of Urban Water System Guangzhou 510006 China department of Science and Environmental studies Hong Kong Institute of Education Hong Kong 00852 China

As a promising in situ remediation technology, nanoscale zero-valent iron （nZVI） can remove polybromi- nated diphenyl ethers such as decabromodiphenyl ether （BDE209） effectively, However its use is limited by its high production cost. Using steel pickling waste liquor as a raw material to prepare nanoscale zero-valent metal （nZVM） can overcome this deficiency. It has been shown that humic acid and metal ions have the greatest influence on remediation. The results showed that nZVM and nZVI both can effectively remove BDE209 with little difference in their removal efficiencies, and humic acid inhibited the removal efficiency, whereas metal ions promoted it. The promoting effects followed the order Ni2＋〉 Cu2＋〉 Co2＋ and the cumulative effect of the two factors was a combination of the promoting and inhibitory individual effects. The major difference between nZVM and nZVI lies in their crystal form, as nZVI was found to be amorphous while that of nZVM was crystal. However, it was found that both nZVM and nZVI removed BDE209 with similar removal efficiencies. The effects and cumu- lative effects of humic acid and metal ions on nZVM and nZVI were very similar in terms of the efficiency of the BDE209 removal.
