Micromorphology and physicochemical properties of hydrophobic blasting dust in iron mines

The micromorphology and physicochemical properties of hydrophobic blasting dust(HBD)from an iron mine were comprehensively analyzed by laser particle size analysis(LPSA),scanning electron microscopy(SEM),X-ray diffraction(XRD),and X-ray photoelectron spectroscopy(XPS).The results show that the HBD particles can be classified into three types based on their particle size(PS):larger particles(PS>10μm),medium particles(1μm≤PS≤10μm),and nanoparticles(PS<1μm).The cumulative volume of respirable dust(PS≤10μm)was 84.45%.In addition,three shapes of HBD were observed by SEM:prism,flake,and bulk.In particular,the small particles were mostly flaky,with a greater possibility of being inhaled.Furthermore,the body and surface chemical compounds of HBD were determined by XRD and XPS,respectively.Ammonium adipate(C6H16N2O4)was the only organic compound in the body of HBD,but its mass fraction was only 13.4%.However,the content of organic C on the surface of HBD was 85.35%.This study demonstrated that the small-particle size and large amount of organic matter on the surface of HBD are the main reasons for its hydrophobicity,which can provide important guidance for controlling respirable dust in iron mines.     

Equilibrium,Kinetics and Thermodynamics of the Adsorption of Methylene Blue onto a Metal-Organic Frameworks Material,Copper Coordination Polymer with Dithiooxamide

The equilibrium, kinetics and thermodynamics of the adsorption of methylene blue （MB） from aqueous solution onto copper coordination polymer with dithiooxamide （H2dtoaCu） , one of the metal-organic frameworks （MOFs）, were investigated in a batch adsorption system as a function of initial pH, adsorbent concentration, contact time, initial dye concentration, and temperature. The Langmnir, Freundlich, and Dubinin- Radushkevich （D-R） isotherm models were used for modeling the adsorption equilibrium. It was found that Langmuir model yielded a much better fit than the Freundlich model under different temperatures. The maximum monolayer adsorption capacities of MB were 192.98, 229.86, and 297.38 mg/g at 298, 308, and 318 K, respectively. The calculated mean adsorption energy （8.26- 11.04 kJ/mol） using D-R model indicated that the adsorption process might take place by chemical adsorption mechanism. Otherwise, the kinetic studies revealed that the adsorption process could be well explained by pseudo-second-order rate kinetics and intraparticle diffusion was not the rate-limiting step. Thermodynamic studies indicated that this system was feasible, spontaneous, and endothermic process. Based on these studies, H2dtoaCu can be considered as a potential adsorbent for the removal of MB from aqueous solution.     

苏北地区城镇化历程、问题及对策研究

改革开放以来,苏北地区城镇化经历了波动徘徊—缓慢发展—快速发展—稳步发展等主要阶段。当前总体上正进入城镇化中期的快速扩展阶段,但存在城镇化与工业化较大脱节、城镇化质量不高、大城市蔓延和低密度扩散趋势加剧、城乡生态环境亟待改善等突出问题。顺应城镇化发展的新特点及新趋势,应当坚持以科学规划为引领,充分发挥城乡规划在城市建设和区域发展中的龙头作用;坚持以农业产业化为基础、工业化为先导的产业支撑型城镇化发展理念;坚持以基础设施建设为重点,完善城镇功能,增强中心城市辐射带动能力;坚持大中城市和小城镇分工协调、城镇聚合轴和都市圈有机结合的战略布局,优化城镇化发展格局;坚持优先发展特色镇、重点中心镇的“小城镇、大战略”,以科学分类考核推动城镇化科学发展。
