Transport Tributyl phosphate

A diverse range of neutral organic molecules has been used to stabilize or to enhance the solubilities of neutral metal-containing entities in an organic phase. Some examples of commercial significance are listed in Table 6. When used alone they efficiently transport metal salts across a circuit. An example is the use of tributyl phosphate (TBP) in recovery of uranyl nitrate,...

Extraction on a micro scale was reported for the transfer of iron ions between aqueous hydrochloric acid and tributyl phosphate/xylene solutions [31]. In this device the two immiscible Hquids were conducted through two channels, which were in partial contact with each other. Surface tension ensures that the two liquids stay in the corresponding chaimels and do not mix. Mass transport in liquids with diffusion coefficients in the range of 10 nf s require path lengths of 30 to 100 pm to achieve transfer in about 1 s. It was shown that the described device, which was fabricated from silicon and glass, could perform the extraction effectively.
