A novel functional fiber(PAN-CDs) loaded with carbon dots(CDs) with excellent photoreduction and adsorption properties for Cr(VI) was prepared via an amidization reaction between the CDs’ carboxyl groups and amine groups on polyacrylonitrile(PAN)-based ion exchange fibers, which could completely preserve the fluorescence properties of the CDs. The photoluminescence(PL), photocatalysis and adsorption properties of PAN-CDs were characterized and analyzed. The PAN-CDs possess high adsorption capacity(297.6 mg/g) and excellent kinetic behavior(attaining adsorption equilibrium in 30 min)for Cr(VI) adsorption. Furthermore, the residual Cr(VI)(approximately 3 mg/L) after adsorption could be removed completely by subsequent photoreduction by the *** Cr-saturated PAN-CDs could be easily separated by filtering and regenerated, with no observable decay of removal efficiency after five regeneration cycles. In addition, due to the PL quenching action of Cr(VI), the PAN-CDs can also be used as sensor for quantitative detection of trace Cr(VI) in aqueous solution.

Pyogenic liver abscesses usually occur in association with a variety of diseases. Rarely, liver abscess has been reported as the presenting manifestation of colonic tubulovillous adenoma. We report two cases of pyogenic liver abscess without hepatobiliary disease or other obvious etiologies except that one had a history of diabetes mellitus （DM）. The pathogen in the patient with DM was Klebsiella pneumonia （KP）. In both of the patients, Ueus developed about two to three weeks after the diagnosis of liver abscess. Colonoscopy revealed large polypoid tumors with pathological findings of tubulovillous adenoma in both cases. Two lessons were learned from these two cases：（1） an underlying cause should be aggressively investigated in patients with cryptogenic liver abscess; （2） DM could be one of the etiologies but not necessarily the only cause of KP liver abscess.

三维共价有机框架(3D COFs)是一种由有机构筑基元通过共价键连接而成的三维网状晶态有机多孔材料,具有高比表面积、复杂孔道结构和大量开放功能位点,在气体吸附与分离及催化等领域展现出了独特的应用前景.由功能基团构筑3D COFs可赋予其特征的性质及功能,然而普遍采用的直接构筑法可能存在合成困难、功能基团不兼容及结构解析难度大等问题.作为一种迂回的构筑策略,后合成修饰法可有效避免3D COFs直接构筑过程中存在的上述问题,从而引起了科研工作者的关注.本文综述了3D COFs共价后修饰及配位后修饰的研究进展,并对其未来发展前景进行了讨论.

CO2/H2S是油气田采集、运输、处理过程中主要的腐蚀介质,由其引起的管道设备的腐蚀问题变得越来越严重,腐蚀和防腐已经成为研究热点。分别对近年来国内外开展的有关CO2和H2S共存腐蚀及缓蚀技术的研究进行综述。CO2/H2S共存腐蚀研究主要依靠试验手段,但目前的研究结果有很大的离散性,根据不同的试验条件会产生不同的研究结果。分压比是国内外大多数学者研究CO2/H2S腐蚀规律的切入点,但关于两者主导腐蚀的分压比界限划分现有研究存有争议。缓蚀技术研究讨论了缓蚀剂作用机理,评述了抑制CO2/H2S共存腐蚀常用的酰胺类、咪唑啉衍生物类、季铵盐类和Schiff碱类缓性剂在国内外的研究与应用现状,展望了这一领域的研究前景及发展方向。

近年来云南省能源消耗不断上升,对环境的负面影响越发显著。库兹涅茨曲线分析表明经济是能源消耗的驱动因素,且近阶段云南省不存在U型线的拐点,能源消耗将随着经济发展而逐年增加。故本文选取人口、人均GDP、工业GDP比率、城市化率、能源消耗强度五个因素作为自变量,以云南省2000~2013年能源消费总量为样本结合主成分分析法和多元线性回归,构建STIRPAT模型。研究结果显示：人口和城市化率是影响云南省能源消耗的关键因素,人均GDP和工业GDP比率对于能源消耗有驱动作用,而能源消耗强度对于能源消耗有抑制作用。针对目前现状,为云南省＂十三五＂期间的节能减排,提出相应建议和对策。

目的在以含油污泥为阳极底泥的沉积型微生物燃料电池(SMFC)体系中,通过改变产电微生物种类和分布方式,探究产电微生物对SMFC产电及降解性能的影响。方法通过采集输出电压、功率密度、表观内阻来检测石油去除率,比较了不同单菌-SMFC、不同混合菌-SMFC的产电性能和降解性能,考查了菌种分布对SMFC性能的影响。结果在单菌-SMFC中,弗氏柠檬酸杆菌-SMFC的产电及降解性能均优于其他5种单菌构筑的SMFC;混合菌-SMFC的产电及降解性能较单菌-SMFC有较大提升,且其中蜡样芽孢杆菌+中间苍白杆菌-SMFC的产电及降解性能最优,输出电压可达到515.30 mV;菌种分布在阳极材料中和阳极底泥中都可以降解含油污泥中的有机物,但是菌种分布在阳极材料中更有利于SMFC产电性能及降解性能的发挥。结论混合菌相对于单菌能够显著提升SMFC的产电及降解性能,而且菌种分布在阳极材料中更有益于SMFC产电性能及降解性能的发挥。

目的以长庆油田某区块钻井污水为例,解决钻井污水产量大、组分复杂和Ca^(2+)等多价离子含量高,且经常规工艺处理后污水仍难以满足压裂液回配性能要求的问题。方法基于以上难解工艺特征,提出多官能团壳聚糖改性螯合Ca^(2+)新型除钙工艺,并对其除钙效果、除钙机理、适用条件(温度、pH)、环境影响(产泥量)及回配性能进行了评价。结果以高脱乙酰度壳聚糖为原料,过硫酸钾作引发剂接枝丙烯酸,在温度为70℃,m(壳聚糖)∶m(过硫酸钾)∶m(丙烯酸)=1.0∶1.2∶25.0的条件下反应2 h可制得高水溶性多官能团SZ-1螯合剂,采用质量浓度为600 mg/L的SZ-1可将Ca^(2+)质量浓度螯合去除至500 mg/L以下;SZ-1在10~40℃、pH为6~14条件下均适用,产泥量低(0.016 g/L),回配压裂液基液黏度较优(30.9~31.2 mPa·s),满足SY/T 7627—2021《水基压裂液技术要求》的基液黏度范围要求(10~40 mPa∙s)。结论该药剂绿色清洁、性能优异、制备简单,有望为油气田高含钙钻井污水处理提供新方法。
