Autor: Takahiko Kakoi, Tadashi Hano, Masahiro Goto, Fumiyuki Nakashio, Shintaro Furusaki, Fukiko Kubota

Publikováno v: Journal of Membrane Science. 165:149-158

Extraction of three rare earth metals (Er, Ho and Y) was performed by a microporous hydrophobic hollow-fiber membrane extractor using a novel calix[4]arene carboxyl derivative in toluene. It was found that the permeation rate through the membrane of

Separation of Cobalt and Nickel by Liquid Surfactant Membranes Containing a Synthesized Cationic Surfactant

Autor: Takahiko Kakoi, Tsuyoshi Ura, Fumiyuki Nakashio, Henry Kasaini, Masahiro Goto

Publikováno v: Separation Science and Technology. 33:1163-1180

Separation of cobalt(II) and nickel(II) by using a hydroxyoxime extractant has been investigated both in liquid-liquid extraction and in a liquid surfactant membrane(LSM) system. In the liquid-liquid equilibrium extraction studies, hydroxyoximes show
