处理后选矿废水中残余的聚丙烯酰胺(PAM)影响回水水质及其回用,本文为建立一种低检出限的低浓度PAM快速检测方法,在190~300 nm波长范围内建立了4种类型及分子量不同PAM的紫外吸收光谱,研究了不同浓度K^(+)和Ca^(2+)对PAM浓度检测的影响,并通过原子力显微镜(AFM)分析了PAM分子构象的变化.结果表明,4种类型的PAM峰值吸光度均在波长194 nm处测得,PAM浓度与吸光度之间具有强线性关系(R^(2)>0.98),检出限均低于0.1 mg·L^(-1),但PAM类型影响其浓度与吸光度的线性关系.随着K^(+)和Ca^(2+)浓度的增加,PAM溶液吸光度特征峰的强度逐渐降低并降速减缓,最大吸收波长不断红移,分别沉积在二氧化硅和金基底的APAM-3与CPAM-12的表面形貌粗糙度分别随K^(+)和Ca^(2+)浓度的增加而增大,说明PAM分子链在溶液中的构象逐渐变卷曲,使紫外光谱特征吸收峰的峰值降低,10、100 mmol·L^(-1) K^(+)与1、10 mmol·L^(-1) Ca^(2+)对PAM构象变化的影响程度基本相同.本研究实现聚丙烯酰胺的快速定量检测,对开展选矿水处理中聚丙烯酰胺的迁移规律研究具有重要意义.

Polycrystalline BiFeO3 and rare earth substituted ***3 （BRFO, R=Y, Ho and Er） compounds were prepared by rapid solid state sintering technique. Structural phase analysis indicated that all the compounds stabilized in rhombohedral structure （R3c space group） and a small orthorhombic phase fraction was observed in BRFO compounds. From the Raman spectra results, the changes in the phonon frequencies （A1） and line widths suggested lattice distortion in the BRFO compounds as was evidenced in the XRD analysis. Compared to the linear variation of magnetization with magnetic field （M-H） shown by BFO, an obvious M-H loop was observed in BRFO compounds which could be due to the suppression of space modulated spin structure and was explained on the basis of weak ferromagnetism and field induced spin reorientation. UV-Vis spectroscopy evidenced a change in local FeO6 envi- ronment due to shift in the 6Alg→4t2g energy transition band. BRFO compounds with improved remnant magnetization and coercive field are applicable for magnetoelectric devices.

研究了玄武岩纤维棒(BFB)的纤维增强指数I_(R)对玄武岩纤维棒聚合物混凝土(BFB-PC)韧性指标t_((2(n-1)))(n)的影响,通过分形理论探究了t_((2(n-1)))(n)与裂缝形貌的关系,并建立了弯曲韧性计算模型.结果表明:当IR=90.0时,BFB对BFB-PC的增韧效果最优,此时BFB-PC的弯曲韧性比未掺BFB时提升了8.39倍;BFB的增韧阈值为IR=37.5和IR=90.0;当IR相同时,与未掺聚合物的混凝土相比,聚灰比为0.06的BFB-PC t_((2(n-1)))(n)更高;IR越大裂缝形貌越复杂,t(2(n-1))(n)与裂缝分形维数呈二次函数关系;本文提出的弯曲韧性计算模型准确描述了BFB对PC梁的增韧作用,其试验值与理论值的相对误差小于15.00%.

the badland topography of Basanputti Village, Ganjam District, Odisha, possesses red sediments. the typical red sediment deposit, on average, consists of 71.8% total heavy minerals （tHM）, out of which 62.1% are ilmenite. the other heavy minerals sillimanite, zircon, garnet, monazite, and pyriboles are in the order of abundance identified. In this present study, Mozley mineral separator has been used to recover tHM from red sediment. Mineral separator results indicate that a product ob- tained contains 72.2% by weight with 94.4% tHM and 95% recovery. the ilmenite concentrate recov- ered using dry low-intensity magnetic separator from the tHM concentrate can be used in pigment in- dustries after suitable pyrometallurgical/chemical processing methods.
