    • 摘要: 以重晶石单矿物为研究对象,捕收剂选用十二烷基磺酸钠、油酸钠、733及十二胺,通过pH值、捕收剂类型及用量条件试验发现,四种捕收剂中十二烷基磺酸钠对重晶石捕收能力最强,其次是油酸钠,733与十二胺对重晶石捕收能力相对较弱.通过Zeta电位测试、红外光谱检测试验及Materials Studio软件模拟发现,重晶石在溶液中解离时,沿(001)面完全解离.由于重晶石晶体结构中Ba—O键(键长0.2814 nm)相比S—O键(键长0.1448 nm)要长,因此其容易断裂,导致矿物表面主要暴露大量带正电的Ba2+离子和荷负电的O2-离子,带正电的钡离子Ba2+与十二烷基磺酸根离子(C12H25OSO3-)容易发生化学吸附而生成十二烷基磺酸钡,使矿物疏水上浮.

    • 摘要: 利用SDS(十二烷基磺酸钠)对壳聚糖进行改性,用于吸附水中的Cu(Ⅱ).阐述了p H、初始吸附浓度、吸附时间以及温度等对吸附的影响.结果表明,在p H=5.5时吸附效果最佳;对Cu(Ⅱ)的吸附过程在30 min达到平衡,最大吸附量为219.22 mg/g;温度对材料的吸附量的影响较小.此方法比用CS材料达到平衡时间缩短3.5 h,最大吸附量增加近1倍.表明通过此方法改性壳聚糖能有效的提高材料对Cu(Ⅱ)的吸附速率和吸附量.红外表征结果表明,SDS的磺酸根离子与CS中的羟基(-OH)进行了结合.%The chitosan was modified by SDS (sodium dodecyl sulfonate).The effects of pH, initial adsorption concentration, adsorption time and temperature on the adsorption process were described.The results show that the adsorption effect is the best when pH=5.5.The adsorption equilibrium achieved in30 min, maximum adsorption quantity of Cu (Ⅱ) is 219.22 mg/g;At the same time, the influence of temperature on the material of the adsorption is small.Compare with CS, this method shortens the balance time by 3.5 h and increases the maximum adsorption amount by nearly one time.It shows that this modification can greatly improve the adsorption rate and adsorption capacity of this material.The FTIR results showed that the sulfonate ions of SDS were combined with hydroxyl (-OH) in chitosan.

    • 摘要: 为了提升天然非金属矿物对Cd2+的吸附性能,采用MT(蒙脱石)和HP(海泡石)为前驱材料,依次通过酸纯化和SDS(十二烷基磺酸钠)改性后合成了有机非金属矿物材料,利用扫描电镜(SEM)、傅里叶变换红外光谱(FT-IR)、X射线荧光光谱分析(XRF)等手段对2种改性材料[SDS-MT(十二烷基磺酸钠改性蒙脱石)和SDS-HP(十二烷基磺酸钠改性海泡石)]吸附Cd2+的机制进行探究,并对吸附过程分别进行了动力学拟合和等温吸附方程拟合.结果表明:(1)SDS-MT和SDS-HP吸附模拟废水中Cd2+的效果分别比未改性的MT和HP平均提升约40%和19.5%.(2)改性过程没有改变2种前驱材料的基本结构,但引起其元素质量分数、阳离子交换量和比表面积的改变.(3)SDS-MT、SDS-HP对模拟废水中Cd2+的吸附量受溶液的p H影响较大,最大吸附量分别达16.54、9.24 mg/g,2种改性材料对模拟废水中Cd2+的吸附过程能较好地满足准二级动力学方程,并且其平衡传质时间较短.(4)SDS-MT对模拟废水Cd2+的吸附模型较满足于Freundlich吸附等温模型,推测SDS-MT是一种有限吸附位点的吸附剂,吸附过程为单分子层吸附,而SDS-HP则较好的满足Langmuir吸附等温模型.研究显示,对2种天然非金属矿物材料的有机改性能够有效提升材料对Cd2+的吸附容量,发挥材料的实际运用价值.%In order to enhance the removal of Cd from wastewater by natural non-metallic minerals, Montmorillonite (MT) and Sepiolite (HP) were used as precursors and were modified by acid purification and Sodium dodecyl sulphater (SDS).The mechanism of Cd2+adsorption by the two modified materials was analyzed by SEM, FT-IR and XRF.The adsorption properties of the two modified materials were fully characterized by adsorption kinetics and adsorption isotherms.The results showed that: (1) The percentages of Cd adsorption by Sodium dodecyl sulfate modified montmorillonite (SDS-MT) and Sodium dodecyl sulfate modified sepiolite (SDS-HP) were about 40%and 19.5%, which are higher than those of the untreated minerals. (2) During the modification process, the basic structures of the two precursors were not changed, while elemental mass fraction, cation exchange capacity, and specific surface area of both modified materials were changed. (3) The sorption of Cd2+by SDS-MT/SDS-HP was strongly p H dependent and the maximum adsorption capacities were 16.54and 9.24 mg/g.The kinetic process of Cd2+adsorption on the SDS-MT/SDS-HP was well fitted by the pseudo-second-order kinetic model and the adsorption equilibrium time of the two materials was shorter.The Cd2+adsorption on the SDS-MT could be better described by the Freundlich model, suggesting SDS-MT is a monolayer adsorption process with limited adsorption sites, whereas the sorption on SDS-HP could be better described with the Langmuir model.Therefore, the organic modification of two natural mineral montmorillonite and sepiolite can effectively improve the adsorption capacity of Cd2+and exert the maximum use value of the materials.

    • 摘要: Objective:To compare the effects of ionic detergent SDS with sodium deoxycholate so as to find a suitable method to obtain lung scaffolds which simulate natural differentiated extracellular matrix that promote cellular adhesion and differentiation.Methods:Sixty SD rats were randomly divided into normal group,SDS group and sodium deoxycholate group with 20 rats in each group.The heart-lung association was taken in each group.In both acellular groups,the rats were acellulared via the right ventricle and the pulmonary artery catheter was placed.In group A,perfusion was made with heparin,Triton X-100 and SDS solution followed by deionized water.Perfusion in group B was made with heparin,Triton X100,sodium deoxycholate solution and deionized water.Each scaffold was observed with scanning electron microscope.H-E staining and Masson trichrome staining were used to detect the residual cells and the nuclear component.Immunofluorescence staining was used to detect the residual quantity of laminin and fibronectin,and the DNA content was measured.Results:Scanning electron microscopy showed that the alveolar structure of SDS group scaffolds were more complete than sodium deoxycholate group.H-E staining showed no obvious cell and nuclear component remained after decellularization of SDS group.Residual nuclear component was found in sodium deoxycholate group.Masson staining showed that SDS group scaffolds had more elastic fibers than sodium deoxycholate group scaffolds.Immunofluorescence showed SDS group scaffolds kept more laminin and fibronectin protein than sodium deoxycholate group.The content of DNA of SDS group (35.28±8.20 ng/mg) was much lower than that in sodium deoxycholate group (52.33 ± 7.67 ng/mg) and the difference was statistically significant.Conclusion:Both the two kinds of reagents can eliminate the nuclear component in the lungs while maintaining extracellular matrix,but SDS perfusion is proved to be better than sodium deoxycholate perfusion.%目的:比较离子型洗涤剂十二烷基磺酸钠(SDS)与脱氧胆酸钠针对肺去细胞支架制备的性能,寻找一种合适的肺去细胞方法以得到模拟可以促进细胞附着和分化天然细胞外基质的肺功能架构.方法:SD大鼠随机分成正常对照组、去细胞SDS组、去细胞脱氧胆酸钠组,分别取心、肺联合体,两组去细胞组均经右心室置入留置针至肺主动脉.去细胞SDS组使用肝素、Triton X-100、SDS溶液和去离子水依次灌注;去细胞脱氧胆酸钠组使用肝素、Triton X-100、脱氧胆酸钠溶液和去离子水依次灌注.各组分别采用扫描电镜观察支架结构;H-E染色、Masson三色染色观察残留细胞、细胞核成分;免疫荧光染色观察肺组织层黏连蛋白、纤维连接蛋白保留情况,并进行DNA含量测定.结果:扫描电镜显示去细胞SDS组支架肺泡结构较去细胞脱氧胆酸钠组完整;H-E染色显示去细胞SDS组肺支架未见明显细胞及细胞核成分残留,去细胞脱氧胆酸钠组可见少量细胞核成分残留;Masson染色显示去细胞SDS组弹性纤维保留优于去细胞脱氧胆酸钠组;免疫荧光显示去细胞SDS组层黏连蛋白和纤维连接蛋白结构较去细胞脱氧胆酸钠组完整,保留度较高;去细胞SDS组DNA含量为(35.28±8.20) ng/mg,明显低于去细胞脱氧胆酸钠组(52.33±7.67) ng/mg,差异有统计学意义.结论:两种去污剂均可有效清除肺内细胞成分,较好地保留细胞外基质,其中SDS溶液灌注法优于脱氧胆酸钠溶液灌注法.

    • 摘要: CTMAB/SDS/Graphene combined modified bentonite(CSGMB) was prepared by using hexadecyl trimethyl ammonium bromide(CTMAB), sodium dodecyl sulfonate(SDS) and graphene as modifier together. The modifying process was conducted by microwave irradiation. The adsorption of the combined modified bentonite on phenol was investigated and the structure was characterized by XRD, SEM, N2adsorption-desorption. The results showed that, the removal rate of CSGMB on phenol could reach 79.1%, when the initial phenol mass concentration was 50 mg/L, the pH value was 3, the adsorption time was 120 min, and the dosage was 2 g/L. The combined modified bentonite could effectively be recycled four times by using 1.5 mol/L NaOH solution, the removal rate after regeneration were 53.88%. Graphene and organobentonite composite uniformly and the pore structure was better than that of bentonite. The basal spacing had increased from 1.287 nm to 1.578 nm and the surface area had increased to 32.998 m2/g.%在微波条件下,采用十六烷基三甲基溴化铵(CTMAB)、十二烷基磺酸钠(SDS)、石墨烯为改性剂,制备CTMAB/SDS/石墨烯复合改性膨润土(CSGMB),研究了改性膨润土对苯酚废水的吸附效果,并通过XRD、SEM、N2吸附-脱附等手段进行了表征.结果表明,苯酚模拟废水初始质量浓度50 mg/L,pH值为3,吸附剂用量2 g/L,吸附时间120 min时,溶液中苯酚的去除率可达79.1%;利用1.5 mol/L NaOH溶液对复合改性膨润土解吸再生,4次再生后对苯酚的去除率为53.88%.复合改性膨润土孔隙结构优于原土,层间距由1.287 nm增大至1.578 nm,比表面积增大至32.998 m2/g.
