摘要： 为掌握竹原纤维制备过程各阶段试样的形态结构和理化性能,更好地开发利用竹原纤维,采用扫描电镜法、红外光谱分析法、X射线衍射法、热重分析法和X射线光电子能谱(XPS)对竹原纤维加工成形各阶段样品进行了纵向测试分析。指出:竹单纤维呈圆形截面,中腔有微小的溶胀趋势,纵向有胶质黏连;竹原纤维制备过程并未改变天然竹纤维的结晶结构与属性,但结晶度呈递增趋势;竹原纤维制备过程各试样主要官能团结构无明显变化;试剂的使用改变了纤维表面的化学变化,C-C相对其他的碳含量降为73.33%,木质素降解、部分结构变化。

摘要： 土壤修复是“十四五”期间国家重点支持的环保领域,是实现社会可持续发展的重要保障。与其他方法相比,植物修复技术整体优势突出,对于土壤重金属的去除净化更为有效。原生质体是植物细胞代谢活动的重要场所,相对于细胞壁而言,原生质体对重金属胁迫的生理响应同样强烈。现阶段,同类植物修复机制研究多从分子生物学层面切入;本研究则从谱学角度展开,初步探究植物原生质体对土壤重金属的反馈信号。以代表性的菊科植物金盏菊为研究对象,通过Pb/Cd胁迫盆栽实验获取金盏菊样本,差速冷冻离心法得到金盏菊原生质体。引入Tessier连续提取-原子吸收光谱法(AAS)揭示胁迫强度与Pb/Cd赋存形态的内在关联,结合X射线衍射光谱(XRD)、傅里叶变换红外光谱(FTIR)、二维相关红外光谱(2D-IR)和X射线光电子能谱(XPS)识别金盏菊原生质体对Pb/Cd响应的谱学表现。结果表明:金盏菊原生质体可交换态Pb/Cd比例不高,胁迫强度对不同形态Cd含量影响很小。XRD图谱最强信号出现在31.7°(NaCl晶体),同时检测出Pb盐[Pb_(5)(PO_(4))_(3)Cl]和Cd盐(CdS)特征峰。FTIR图谱的3510 cm^(-1)附近强吸收带源于—OH伸缩振动,胁迫过程导致峰形杂乱、峰位偏移;2D-IR结果说明Pb/Cd优先与金盏菊原生质体—OH和C O结合。从XPS图谱可以看出,反应前后原生质体C,O元素结合能有异。C(1 s)结合能略有增加,说明C原子参与了配位反应;O(1 s)峰位有所偏转,暗示含O基团对Pb/Cd的结合包含多种途径。新出现的Pb(4 f)峰源于π电子-Pb的交互作用;胁迫浓度增加导致Cd(3 d)结合能升高,表明Cd具有明显失电子倾向。相关结果可以与前期获得的Pb/Cd/金盏菊细胞壁结合特性互为补充,对于完善同领域的深度和广度、构建植物修复理论和技术体系意义重大。

摘要： 基于SEM-EDS,XPS,获得常温常压下SCR废催化剂二段式浸出新工艺,采用Box-Behnken试验设计(BBD)方法分段研究了各因素及其交互作用对钒和钨浸出影响,得到了最佳工艺参数,并分析了浸出机理.结果表明,采用二段式浸出工艺,各因素影响顺序为:第一阶段提钒,反应温度>浸出时间>浸出剂浓度;第二阶段提钨,反应温度>浸出剂浓度>浸出时间.第一段当NaOH浓度0.5 mol·L^(-1),60°C下反应10 min时,钒浸出率为(61.40±0.24)%;第二段当NaOH浓度2.5 mol·L^(-1),90°C下反应50 min时,钨浸出率为(55.73±0.22)%.废催化剂中钒以V_(2)O_(3),VOSO_(4)和V_(2)O_(5)形式存在,与NaOH反应生成可溶性钒酸盐,少部分V_(2)O_(3)和V_(2)O_(5)在反应过程中生成VOSO_(4)后溶解.

摘要： 针对在XPS样品制备过程中可能遇到的污染问题,通过XPS测定表面元素分布情况,研究了几种潜在污染源表面的化学组成,及其在特定条件下的污染转移对样品测试数据的影响。实验结果表明,手指、手套对样品的污染会引入C、Na、Si等元素,一次性培养皿对样品的污染会引入Zn元素。污染源对样品的定性、定量分析均造成严重干扰。深入理解制样要求,进行正确规范的操作可有效杜绝污染对测试结果的影响。

摘要： 以硅胶为核,马来海松酸丙烯酸乙二醇酯和甲基丙烯酸为功能单体,采用涂覆悬浮聚合法合成了核壳型SiO_(2)@松香基阳离子交换树脂(SiO_(2)@RCER),研究了其对水中微量Cd^(2+)的静态吸附性能。结果表明,在Cd^(2+)溶液浓度为0.5 mg·L^(-1),pH=6.0,温度为303 K,吸附剂用量为10 g·L^(-1)时,Cd^(2+)去除率可达到100%;SiO_(2)@RCER对Cd^(2+)的吸附符合准二级动力学方程以及Langmuir吸附等温线,表明吸附过程为单分子层化学吸附。吸附前后材料的XPS图谱表明:SiO_(2)@RCER对Cd^(2+)吸附主要涉及Na^(+)以及溶液中的Cd^(2+)的阳离子交换。该吸附剂在对Cd^(2+)、Pb^(2+)浓度超标的矿区废水吸附处理后,高毒重金属浓度均达到国家生活饮用水水源水质一级标准(CJ3020-93),其他离子浓度也有所降低。

摘要： 以山西柳湾和两渡的炼焦精煤为研究对象,利用热重分析(TG-DTG)、X射线光电子能谱(XPS)和红外光谱(FTIR)等测试技术,研究了室温环境下溴水脱硫对煤自燃特征温度与煤活性基团的影响。结果表明:随着脱硫次数增加,煤进入氧化增重阶段的起始温度向高温区偏移,煤进入快速燃烧阶段与达到最大失重速率的温度点均向低温区偏移,即煤的氧化自燃进程加快。煤的发热量呈下降趋势,但最多仅降低原煤发热量的3.4%。煤表面C元素、N元素和S元素含量随着脱硫次数的增加而规律性地减少,而O元素含量呈增加趋势,煤中硫醇、硫醚、噻吩、芳碳、碳氢键碳与质子化吡啶等官能团相对含量逐渐降低,砜、亚砜、羧基、羰基、吡啶、吡咯与氮氧化物等含氧官能团相对含量逐渐增加,说明脱硫后煤中各元素以更高的价态存在,溴水脱硫是一个氧化过程。IR光谱显示芳香族官能团和脂肪烃官能团中的C—H键伸缩振动锋均变弱,含氧官能团中的C=O双键和酚羟基中的C—O—H键伸缩振动峰均变强,说明煤中C—H键含量减少,C=O双键和C—O—H键含量增大,这与TG-DTG和XPS的分析结果相一致,说明脱硫后煤中的C元素、S元素和N等元素被氧化,煤的氧化程度变高。

摘要： 认识煤中主要元素的赋存特征,是构建煤大分子结构的基础。本文采用工业分析、元素分析以及X射线电子能谱解析山西阳煤二矿无烟煤碳、氢、氧、氮和硫的赋存特征。结果表明:山西阳煤二矿无烟煤中碳的主要赋存形式为芳香碳和脂肪碳,碳碳单键的含量最高占82.34%,碳氧键的含量次之,占11.01%,碳氢键占6.17%,说明无烟煤存在一定的烷基侧链,羧基含量最低仅占0.48%。醚基氧和羟基氧占氧元素的82.51%,羰基占13.67%,羧基占3.82%。氮元素主要以吡咯氮和吡啶氮等有机氮形式存在,其中大部分存在于煤分子边缘,吡咯氮由于其芳香共轭体系的稳定性含量最多,占氮元素的41.28%,吡啶氮含量次之占25.24%,质子化吡啶含量占17.36%,主要镶嵌于芳香结构的内部,氮氧化物含量最少,占16.12%;硫元素存在形式以有机硫为主,无机硫为辅,分别占硫元素的74.03%和25.97%。有机硫中噻吩类硫含量最多占硫元素总量的35.34%,砜和亚砜占32.30%,无机硫占25.97%,硫醇和硫醚占6.39%。

摘要： 为了研究煤中赋存的硫生成二氧化硫与加热温度之间的定量关系,采用X射线光电子能谱仪(XPS)、热重分析-傅立叶变换红外光谱联用仪(TGA-FTIR)、智能库仑测硫仪研究了煤炭中各形态硫的赋存状态、煤的热重曲线、二氧化硫的红外光谱图等,进行了煤在不同加热温度下逸出二氧化硫的测试试验。试验结果表明二氧化硫逸出量与温度之间存在可定量的关系,二氧化硫逸出温度与硫在煤中的赋存形态相关:当温度低于400°C时,逸出的二氧化硫与有机硫相对应;当温度在400~900°C之间时,逸出的二氧化硫与硫铁矿硫相对应;当温度高于900°C时,逸出的二氧化硫与硫酸盐硫相对应。该研究成果对煤炭硫脱和煤中各形态硫检测结果的快速审查核验有重要意义。

摘要： 为探究玻璃纤维网对XPS材料火灾危险性的影响,利用热重仪测得材料XPS的热解特性参数,通过锥型量热仪获得XPS与常见3种孔径的玻纤网复合层的燃烧特性参数,采用层次分析法计算出与不同孔径玻纤网复合的保温层的火灾危险程度。实验结果表明:XPS材料从280°C开始热解,在425°C时达到最大热解速率;增加玻璃纤维网会促进XPS的燃烧反应,XPS复合的玻璃纤维网孔径越小,燃烧释放的热量与烟气量越高,火灾危险性越大。说明玻璃纤维网会加剧XPS保温材料的火灾危险,并且在建筑外墙保温设计时应减少或避免使用小孔径的玻璃纤维网。

摘要： 用磁控溅射成功制备出V掺杂ZnO压电薄膜。在不同温度对样品进行退火处理,采用扫描电子显微镜(SEM)、X射线衍射(XRD)和X射线光电子能谱仪(XPS)对薄膜的表面形貌、晶体结构和表面化学状态进行表征,并测量了不同退火温度下薄膜样品的电流密度(J)-电压(V)曲线。结果表明,高温退火后V向ZnO晶格内部迁移,引起晶格畸变,形成表面氧空位。随着退火温度的升高,非线性系数先增大后减小,薄膜的压敏电压逐渐增大,漏电流密度先减小后增大。800°C退火后样品表面氧空位浓度最高,薄膜具有较为理想的综合电性能,其非线性系数为15.19,压敏电压为5.13 V,漏电流密度为0.42μA·mm^(-2)。

摘要： Iron oxides are usually preloaded within nanoporous supports of large particle size to improvetheir feasibility for practical environmental remediation including arsenic and heavy metals removal, andeffect of co-ions on the performance of the resulting composites has been well investigated. However, noattempt has been made to investigate their adsorption behavior of heavy metals in the presence ofcounter-ions, such as sulfate. In this study, two hybrid sorbents (denoted as HFO-PS-and HFO-PS0respectively) were prepared by loading hydrous ferric oxide (HFO) nanoparticles onto different porouspolystyrene hosts, PS-, negatively charged with sulfonic acid groups, and PS0, covalently bonded neutralchloromethyl groups. Experimental results showed clear differences between HFO-PS-and HFO-PS0in theirCu uptake capabilities in the presence of sulfate. The amount of Cu adsorbed on HFO-PS0was markedlypromoted by introducing sulfate, being consistent with bulky HFO particles. As for HFO-PS-, withmonovalent cation as background (Na), it exhibited an apparent decrease in Cu adsorption as a result of thecompeting effect of Na cations and the solution complexation between Cu and sulfate ions. Contrarily, theadsorbed Cu was increased by introducing sulfate in the divalent cation background (Ca), because sulfateions were allowed to access to the loaded HFO nanoparticles due to the screening of the sulfonic acid groupscaused by Ca ions. XPS spectroscopy further demonstrated that the formation of Cu-SO4ternary complexesaccounted for the enhanced Cu sorption both on bulky HFO and hybrid HFO sorbents in the presence ofsulfate. These results indicated that effect of sulfate ligand on metal adsorption to hybrid iron oxides waslargely dependent on the surface properties of the host materials, as well as the loaded HFO.
