    摘要： The invention relates to methods and apparatus for drying [18F]fluoride which comprises (i) passing a [18F]fluoride solution comprising water, a solvent, [18F]fluoride, and a cationic counterion through a narrow bore vessel at elevated temperature such that the water and solvent are vaporised forming a vaporised component, and (ii) collecting the resulting vaporised component by condensing into a collection vessel.

    摘要： The disclosure provides an electrolyte supplement system in an aluminium electrolysis process, which includes low-molecular-ratio cryolite, wherein the low-molecular-ratio cryolite is selected from mKF·AlF 3 , nNaF·AlF 3 or mixture thereof, where m=1∼1.5 and n=1∼1.5. When the electrolyte supplement system provided by the disclosure is applied to the aluminium electrolytic industry, electrolytic temperature can be reduced obviously in the aluminium electrolysis process without changing the existing electrolytic process; thus, power consumption is reduced, volatilization loss of fluoride is reduced and the comprehensive cost of production is reduced.

    摘要翻译： 本发明提供一种铝电解工艺中的电解质补充体系，其包括低分子比冰晶石，其中低分子比冰晶石选自mKF·AlF 3，nNaF·AlF 3或其混合物，其中m = 1/1 0.5和n = 1 / 1.5。 当本公开提供的电解质补充体系应用于铝电解工业时，铝电解过程中的电解温度可以明显降低，而不改变现有的电解过程; 因此，功耗降低，氟化物的挥发损失降低，综合生产成本降低。
