Nitrate removal using supported liquid membranes: transport mechanism
A new method is developed for the removal of nitrate ions from water. Nitrate ions can be removed from water almost completely, with a mobile carrier, by counter-transport of chloride ions through a supported liquid membrane. The transport characteristics of this process, in which the water phases are flowing parallel to flat membranes, are described. The results show that depending on the expe...
متن کاملSupported liquid membranes : instability effects
The instability behaviour of several supported liquid membranes (SLMs) has been studied for a system in which nitrate ions are removed from an aqueous feed phase and concentrated in a stripping phase. The composition of the aqueous phases and of the membrane liquid has been determined after the aqueous phases had flowed parallel to the membranes for a period of six days. From the experimental d...

متن کاملReview on Mechanism of Facilitated Transport on Liquid Membranes
Membrane processes are used in various felds such as the environment, agriculture and different industrial sectors. These clean techniques are often adopted for directed processes such as treatment, recovery, valorization and separation. In this review article, the theoretical principles and the different classifcations of liquid membranes, such as supported liquid membra...
متن کاملSelective Mass Transport of CO2 Containing Mixtures through Zeolite Membranes
In this work, the main aspects regarding the permeation of mixtures containing CO2 and permanent gases such as H2 , N2 and CH4 through zeolite membranes have been investigated, focusing on the description of the mass transport mechanisms taking place inside the pores. First, a brief overview about the performance of the main zeolite membranes used in gas separation (e.g. DDR, CHA, AEI, FAU, etc...
