液膜乳状液稳定性的研究

Study on Stabilities of Emulsion Liquid Membrane

本文实验研究了各种载体以及浓度对液膜溶胀和破裂的影响。结果表明,随着载体浓度的增加,液膜的破碎率和溶胀率都将增大,含有酸性络合萃取剂的液膜最易破碎,离子缔合萃取剂次之,而中性络合萃取剂最低。合理选择载体及用量,有助于提高液膜的稳定性。

The effects of carries and their concerntrations on breakage and swelling of liquid membrane emulsion have been examined experimentally. The results show that the breakage and swelling rate will increase as the concentration of carrier in membrane phase increases. The liquid membarne containing acid complex extractant is the easiest one to break. Next is the membrane containing ion association extractant. The breakage of membrane containing neutral complex extractant is the smallest. Resonable selection of carrier and its concerntration in membrane is helpful to improve the stabilities of liquid membrane emulsion.
