Primary amine Primene JMT and TBP were used as extractants (carriers) in liquid membrane phase. Different experimental variables such as concentration of carbonate ion, carriers, alkali and hydrogen peroxide, stirring speed, etc have been investigated. Primary amine Primene JMT and TBP mixed carriers show the synergistic effect for the transport of carbonate ions through supported liquid membrane system. The stability of the supported liquid membrane system has been explored for 50 h. The pre-concentration of carbonate ions from dilute solutions were also demonstrated. The effect of different alkalis on the permeability coefficient of transport of carbonate ions through supported liquid membrane system has been investigated. The primary amine in combination with TBP shows more effective for the transport of carbonate ions through supported liquid membrane system in comparison with that of secondary and tertiary amines.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">11</style></issue><custom3><style face="normal" font="default" size="100%">Foreign</style></custom3><custom4><style face="normal" font="default" size="100%">1.015</style></custom4></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Gaikwad, Abaji G.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Studies on transport of carbonate ions through a supported liquid membrane</style></title><secondary-title><style face="normal" font="default" size="100%">Chemical and Biochemical Engineering Quarterly</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">alkali metal hydroxide</style></keyword><keyword><style  face="normal" font="default" size="100%">carbonate ions</style></keyword><keyword><style  face="normal" font="default" size="100%">liquid anion and cation exchangers</style></keyword><keyword><style  face="normal" font="default" size="100%">permeability coefficient</style></keyword><keyword><style  face="normal" font="default" size="100%">supported liquid membrane</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2009</style></year><pub-dates><date><style  face="normal" font="default" size="100%">SEP</style></date></pub-dates></dates><number><style face="normal" font="default" size="100%">3</style></number><publisher><style face="normal" font="default" size="100%">CROATIAN SOC CHEMICAL ENGINEERING TECHNOLOGY</style></publisher><pub-location><style face="normal" font="default" size="100%">BERISLAVICEVA 6, PO BOX 123, HR-10000 ZAGREB, CROATIA</style></pub-location><volume><style face="normal" font="default" size="100%">23</style></volume><pages><style face="normal" font="default" size="100%">267-275</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">&lt;p&gt;The transport of carbonate ions through a supported liquid membrane in the presence and absence of carriers has been explored. The liquid membrane used was the combined liquid cation and anion exchangers in toluene immobilized in the porous polypropylene support. The permeability coefficient (P) of carbonate ions transport from the source to receiving through membrane phase has been estimated. The different experimental variables such as the concentration of carbonate ions in source phase, the concentration of Aliquat-336 (tricapryl(methyl)ammonium carbonate) and PC-88A (2-ethyl-hexyl phosphonic acid mono-2-ethylhexyl ester) in membrane phase, alkali metal hydroxide concentration in receiving phase, and the stirring speed of the Source phase and receiving phase have been explored. The stability of liquid membrane phase during the transport of carbonate ions from source phase to receiving phase was tested for 50 h. The enrichment factor for carbonate ion transport from the source to receiving phase was found to be higher at lower concentrations of carbonate ions in comparison with that of at higher concentrations. A model has been developed for the effective transport of carbonate ions through the cross section area of liquid membrane phase from source to receiving phase.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue><custom3><style face="normal" font="default" size="100%">Foreign</style></custom3><custom4><style face="normal" font="default" size="100%">0.483</style></custom4></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Gaikwad, Abaji G.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Transport of carbonate ions through supported liquid membrane by using Alamine 336 and trioctylphosphine oxide as carriers</style></title><secondary-title><style face="normal" font="default" size="100%">Green Chemistry Letters and Reviews</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Alamine 336</style></keyword><keyword><style  face="normal" font="default" size="100%">carbonate ion</style></keyword><keyword><style  face="normal" font="default" size="100%">supported liquid membrane</style></keyword><keyword><style  face="normal" font="default" size="100%">synergic effect</style></keyword><keyword><style  face="normal" font="default" size="100%">trioctyl phosphine oxide (TOPO)</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2011</style></year><pub-dates><date><style  face="normal" font="default" size="100%">MAR</style></date></pub-dates></dates><number><style face="normal" font="default" size="100%">2</style></number><publisher><style face="normal" font="default" size="100%">TAYLOR &amp; FRANCIS LTD</style></publisher><pub-location><style face="normal" font="default" size="100%">4 PARK SQUARE, MILTON PARK, ABINGDON OX14 4RN, OXON, ENGLAND</style></pub-location><volume><style face="normal" font="default" size="100%">4</style></volume><pages><style face="normal" font="default" size="100%">159-169</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">&lt;p&gt;Transport studies were carried out for carbonate ions through supported liquid membrane (SLMs) by sing Alamine 336 and trioctylphosphine oxide (TOPO) as carriers. Experimental variables were investigated, such as concentration of carbonate ion (10(-5) to 4 x 10(-2) M), carriers (10(-5) to 10(-1) M), and alkali (0.01-0.5); and stirring speed (50-50 rpm) of bulk solutions. The use of combined carriers Alamine 336 and TOPO shows a synergic transport of carbonate ions. The stability of the SLM system in relation to the transport of carbonate ions has been studied. The enrichment of carbonate ions (10(-6) to 4 x 10(-2) M) from the dilute solution was explored. The different combinations of amines with TOPO show synergic permeability of the carbonate ions through SLM system.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">2</style></issue><custom3><style face="normal" font="default" size="100%">Foreign</style></custom3><custom4><style face="normal" font="default" size="100%">0.976
