摘要： A separation method of zirconium and hafnium is described which includes an extraction process of agitating an undiluted aqueous solution containing zirconium, hafnium, and sulfuric acid with a first stirring solution containing an acidic extractant to produce a first extract solution in which the hafnium is extracted by the acidic extractant; and a recovery process of agitating the first extract solution with a second stirring solution containing a citric acid solution to produce a citric acid solution after extraction in which zirconium is reverse-extracted from the first extract solution to the citric acid solution so as to recover zirconium contained in the first extract solution. The method may reduce the amount of extractant while greatly enhancing the separation effect of zirconium and hafnium, and increase zirconium recovery rate by more than 97% through an additional zirconium recovery process while reducing a hafnium content in zirconium by less than 50 ppm.

摘要： Disclosed is a carbon felt impregnated with inorganic particles. The impregnated carbon felt can be used together with sulfur in a cathode of a sodium-sulfur (Na—S) battery. Also disclosed is a method for producing the impregnated carbon felt. According to exemplary embodiments, the problem of the prior art can be solved in which inorganic particles such as alumina particles are not directly adhered to carbon felts, thus necessitating complicated processes. In addition, a slurry including an inorganic binder and alumina particles can be used to directly coat the alumina particles on the surface of a carbon felt, making the production procedure very simple. Furthermore, the use of the carbon felt surface coated with the alumina particles in a Na—S battery increases the wicking of sodium polysulfides, suppresses the accumulation of sulfur as an insulator on the surface of beta-alumina as an electrolyte, and inhibits non-uniform aggregation of sulfur or sodium polysulfides on the carbon felt, so that the concentration polarization of charges can be reduced without a significant increase in the internal resistance of the battery, achieving high utilization efficiency of sulfur as a reactant.
摘要翻译：公开了用无机颗粒浸渍的碳毡。浸渍的碳毡可以与硫磺一起在钠 - 硫（Na-S）电池的阴极中使用。还公开了一种生产浸渍碳毡的方法。根据示例性实施例，可以解决现有技术的问题，其中诸如氧化铝颗粒的无机颗粒不直接粘附到碳毡上，因此需要复杂的工艺。此外，可以使用包含无机粘合剂和氧化铝颗粒的浆料直接涂覆在碳毡表面上的氧化铝颗粒，使得生产过程非常简单。此外，使用在Na-S电池中涂覆有氧化铝颗粒的碳毡表面增加多硫化钠的芯吸，抑制作为电解质的β-氧化铝表面上作为绝缘体的硫的积聚，在碳毡上均匀聚集硫或多硫化钠，从而可以降低电荷的浓度极化，而不会显着提高电池内阻，实现硫作为反应物的高利用率。
