“…Biswas et al [14], Wojciechowski et al [15] and Darvishi et al [16] propose the SLM with two carriers to increase the efficiency of the ions transport process. The authors observe that for a specified ratio of the carriers in a membrane, a synergistic effect is obtained and that the rate and selectivity of the process increased.…”

“…Acidic Cyanex series extractants offer high extraction power and their solubility in aqueous solutions is very low, but they are relatively expensive to be used commercially, while D2EHPA is much less expensive [10,21]. The use of mixture of Cyanex272 and D2EHPA as a carrier for rare earths in a supported liquid membrane has not been reported in the literature.…”

“…O sinergismo da extração Ni-Co foi estudada por Darvishia et al (2005) utilizando-se o extratante D2EHPA (di(2-etilhexil) ácido fosfórico) ora com Cyanex 272 ora em presença do Cyanex 302 (bis-(2,4,4-trimetilpentil) ácido monotiofosfínico), obtendo-se melhor separação para o sistema D2EHPA/Cyanex 302. Recentemente, Guimarães (2014) observou que a separação Ni-Ca também poderia ser realizada empregando-se misturas entre Cyanex 272 e D2EHPA, logo o objetivo do presente trabalho é avaliar o sinergismo na separação Ni-Ca utilizando-se uma mistura dos extratantes D2EHPA e Cyanex 272.…”
