摘要

重金属的去除是各行业面临的重要问题。液液萃取是回收这些元素的一种实用方法。在本研究中,评价了圆盘-甜甜圈柱萃取镉离子的中试性能。不同尺寸分布的液滴对描述萃取器从水相或有机相中去除底物的性能和特性具有重要的影响。在稳定条件下,液滴的大小分布与界面面积有关。为了匹配液滴的大小分布,在反应和非反应条件下进行了实验。在脉冲强度(Af)、进口有机相流速和水相流速(Vc、Vd)分别为3.3 cm/s、2.22 mm/s和2.22 mm/s的乳化条件下,在优化条件下,镉的回收率为99.7%。结果表明,威布尔分布在各操作模式下的拟合效果最好,而反高斯分布的拟合效果最差。通过一系列的统计分析表明,脉动强度对液滴粒径的影响较大,两相的表面流速对液滴粒径分布的预测能力较弱。

Feasibility of pilot-scale disc-donut column for continuous cadmium extraction with the perspective of droplet size distribution
ABSTRACT Heavy metal removal is a significant problem in various industries. Liquid-liquid extraction is a practical process in recovering these elements. In this study, the behavior of pilot-scale disc-donut column in the extraction of cadmium ions was evaluated. The effects of droplets with the variation size distributions are significant in describing performance and characteristics of an extractor for removing the substrate from aqueous or organic phases. The size distribution of droplets is relative to the interfacial area under steady conditions. To match the size distribution of droplets, the experiments are carried out in reaction and non-reaction conditions. In emulsion regime (pulsing intensity (Af), inlet organic and aqueous phase flow rate (Vc, Vd) equal to 3.3 cm/s, 2.22 mm/s, and 2.22 mm/s, respectively) and under the optimized conditions, 99.7% of the cadmium can be recovered from the aqueous solution. It was found that Weibull distribution gives the best fit at each operation mode while inverse Gaussian distribution gives the most inferior fit. According to a series of statistical analyses, it is shown that the pulsation intensity imposed more influence on drop sizes, and superficial flow rates of both phases are less able to the successful prediction of size distribution of droplets.
