Single and selective transport of Zr(IV) ions with trioctyl amine dissolved in kerosene using a multidropped liquid membrane technique
نویسندگان
چکیده
It is very important to develop a process for selectively extracting Zr(IV) ions from the solution medium produce zirconium metal used in industry and nuclear reactors. In this study, parameters affecting extraction of were investigated using multidropped liquid membrane (MDLM) system. Trioctyl amine (TOA) dissolved kerosene was as carrier ligand by MDLM technique. The effect concentration stripping concentration, pH, temperature donor phase on transport investigated. optimum condition transportation 0.50 M H2SO4 phase, 0.10 molL-1 TOA carrier, Na2CO4 acceptor phase. percentage increased up >99% calculated activation energy which 6.36 kcal mol-1 indicated that diffusion controlled ions. results showed system, resembles bulky system shape, promising technique an acidic solution. more practical effective than bulk, supported, or inclusion, emulsion techniques.

Selective Liquid-Liquid Extraction of Lead Ions Using Newly Synthesized Extractant 2-(Dibutylcarbamoyl)benzoic Acid
A new carboxylic acid extractant, named 2-(dibutylcarbamoyl)benzoic acid, is prepared and its potential for selective solvent extraction and recovery of lead ions from industrial samples was investigated. The slope analysis indicated that the lead ions are extracted by formation of 1:2 metal to ligand complexes. The effect of the parameters influencing the extraction efficiency including kind o...
