The combined effects of mixed electrolyte species and glucose on oxygen transfer were studied in a bubble column with aqueous solutions. Of particular interest was the presence of electrolytes containing ions which are prone to present solute–solute interactions or to crystallize. Without and at low concentration of glucose (≤ 5 g/L), the increasing concentration of electrolytes (nominal ionic strength: 0–0.43 M), up to a critical value, enhanced the volumetric mass transfer coefficient (k_La) and the availability of specific interfacial area (a), due to the inhibition of bubble coalescence. As the glucose concentration increased (10–40 g/L), the enhancing effects of electrolytes were gradually lost. The glucose interacted with electrolytes, reducing their ability to inhibit coalescence and to enhance the k_La. Salt crystallization occurred independently of the addition of glucose; however, it did not have significant effect on mass transfer. Finally, the changes in physicochemical properties were highly collinear with composition variables.

在含水溶液的气泡柱中研究了混合电解质物质和葡萄糖对氧转移的综合影响。特别令人感兴趣的是含有离子的电解质的存在，这些离子易于呈现溶质-溶质相互作用或结晶。在没有和低浓度葡萄糖 (≤ 5 g/L) 的情况下，电解质浓度的增加（标称离子强度：0-0.43 M），达到临界值，提高了体积传质系数 ( k _L a ) 和特定界面区域的可用性（a)，由于气泡聚结的抑制。随着葡萄糖浓度的增加（10-40 g/L），电解质的增强作用逐渐消失。葡萄糖与电解质相互作用，降低了它们抑制聚结和提高k _L a 的能力。盐结晶的发生与葡萄糖的加入无关；然而，它对传质没有显着影响。最后，物理化学性质的变化与成分变量高度共线。
