Synthesis of sodium magnesium iron sulfate rod-likes as NASICON using the precipitation method

Sodium magnesium iron sulfate rod-likes were synthesized using the tailing by the precipitation method. The density of the tailing sample was determined as 3.45 g/cm³ and 85% of the particle sizes are < 300 μm. In the course of synthesis, the tailing dissolved in the sulfuric acid. The solution was participated using sodium hydroxide. The precipitate was calcinated at 500 °C in the furnace without special atmosphere. X-ray diffraction (XRD) and scanning electron microscopy (SEM) were employed to characterize the prepared product. XRD results showed that sodium magnesium iron sulfate is the desired material. Also, the sample contains a small amount of sodium sulfate. The SEM image proved that the morphology of the sample is rod-like. It was observed that the diameter of the rod-likes was about 100-250 nm.     

尾粉土物理力学指标统计规律研究

采用数理统计及一元回归分析方法,对尾粉土各项物理力学指标进行统计分析,对物理指标间的相关性、物理指标与力学指标间的相关性进行回归分析,并建立了用于指标预测的经验公式。统计分析表明,尾粉土物理力学性质指标的变异性整体上变化不大,相关性较强,对细粒尾矿尾粉土的物理力学指标取值时,可以不考虑其变异性,近似地取其平均值作为设计参数。数据回归得到的回归方程可以估算细粒尾矿尾粉土的一些物理力学特性,为细粒尾矿坝的稳定性研究提供参考。

Canavalia ensiformis Tailing Starch: A Functional Source of Dietary Fiber

Physicochemical and functional characteristics of the tailing starch isolated from the legume Canavalia ensiformis were determined. Proximal composition was 2.86% protein, 4.05% fiber, 0.37% fat, 1.51% ash and 91.33% carbohydrates as nitrogen‐free extract. Total dietary fiber content was 21.3%, soluble fiber was 2.2%, and insoluble fiber was 19.1% as determined by the Prosky method. Amylose content as quantified by differential scanning calorimetry (DSC) was 39.35%. Gelatinization temperature range as determined by DSC was from 77.9 °C to 88.1 °C, with 81.6 °C being the peak temperature. Transition enthalpy was 10.1 J/g. Swelling power ranged from 4.36 g water/g starch at 60 °C to 11.87 g water/g starch at 90 °C. Water solubility, analyzed within the same temperature interval, ranged from 3.29% to 16.93%. Water absorption capacity was 4.22 g water/g starch at 60 °C and 10.33 g water/g starch at 90 °C. Syneresis in a 6% gel stored at 4 °C for 24 h was 25.66 mL water/50 mL gel. Clarity, expressed as transmittance, was 10.46%. Initial pasting temperature was 93 °C, breakdown was —22 Brabender Units (BU), consistency was ‐5 BU, and setback was 17 BU.
