1河南省内四大流域边界提取与水系分析显示文摘【目的】为推动河南省境内流域生态环境保护和高质量发展,准确掌握河南省境内区县和水系在四大流域中的分布情况。【方法】基于数字高程模型(DEM)数据,利用ArcGIS扩展模块ArcHydro Tools提取流域的边界和水系,获得了长江、黄河、淮河、海河四大流域在河南省境内的边界线、5级河流和涉及区县分布图。【结果】河南省境内流域面积最大的是淮河流域(占全省面积的52.70%,涉及的区县最多),其次是黄河流域(21.62%)、长江流域(16.50%)、海河流域(9.18%)。其中,黄河流域涉及的区县,还包括流域外的区县:郑州市的荥阳市、惠济区和金水区,开封市的龙亭区、祥符区和兰考县,因为其位于黄河岸边,虽然根据流域性质它们属于淮河流域,但却是影响黄河和受黄河影响较大的区县;河网密度最大的是长江流域(0.36 km/km^(2)),依次是黄河流域(豫西)(0.30 km/km^(2))、淮河流域(0.27 km/km^(2))、海河流域(0.20 km/km^(2)),河网密度最小的是黄河流域(豫北)(0.15 km/km^(2)),高低顺序与流域水系分布特征完全吻合。【结论】利用ArcHydro Tools提取省级行政区境内流域的边界和水系切实可行,是行之有效的方法。徐海军 魏义长 许澍 LEGHARI Shah Jahan 王同朝 2021灌溉排水学报2021,40,6:2

3Competitive role of nitrogen functionalities of N doped GO and sensitizing effect of Bi_(2)O_(3)QDs on TiO_(2)for water remediation显示文摘The promising solar irradiated photocatalyst by pairing of bismuth oxide quantum dots(BQDs)doped TiO_(2)with nitrogen doped graphene oxide(NGO)nanocomposite(NGO/BQDs-TiO_(2))was fabricated.It was used for degradation of organic pollutants like 2,4-dichlorophenol(2,4-DCP)and stable dyes,i.e.Rhodamine B and Congo Red.X-ray diffraction(XRD)profile of NGO showed reduction in oxygenic functional groups and restoring of graphitic crystal structure.The characteristic diffraction peaks of TiO_(2)and its composites showed crystalline anatase TiO_(2).Morphological images represent spherical shaped TiO_(2)evenly covered with BQDs spread on NGO sheet.The surface linkages of NO-O-Ti,C-O-Ti,Bi-O-Ti and vibrational modes are observed by Fourier transform infrared spectroscopy(FTIR)and Raman studies.BQDs and NGO modified TiO_(2)results into red shifting in visible region as studied in diffused reflectance spectroscopy(DRS).NGO and BQDs in TiO_(2)are linked with defect centers which reduced the recombination of free charge carriers by quenching of photoluminescence(PL)intensities.X-ray photoelectron spectroscopy(XPS)shows that no peak related to C-O in NGO/BQDs-TiO_(2)is observed.This indicated that doping of nitrogen into GO has reduced some oxygen functional groups.Nitrogen functionalities in NGO and photosensitizing effect of BQDs in ternary composite have improved photocatalytic activity against organic pollutants.Intermediate byproducts during photo degradation process of 2,4-DCP were studied through high performance liquid chromatography(HPLC).Study of radical scavengers indicated that O_(2)^(·-) has significant role for degradation of 2,4-DCP.Our investigations propose that fabricated nanohybrid architecture has potential for degradation of environmental pollutions.Saima Noor Shamaila Sajjad Sajjad Ahmed Khan Leghari Cristina Flox Saeed Ahmad 2021Journal of Environmental Sciences2021,33,10:2
