REILLEX™-HPQ ANION EXCHANGE COLUMN CHROMATOGRAPHY: REMOVAL OF PERTECHNETATE FROM DSSF-5 SIMULANT AT VARIOUS FLOW RATES

Cyanex 923 has been proposed as an extractant for the removal of sulphuric acid from copper tank house bleed streams. This process requires many stages and so is ideal for column operation. This paper presents a comparison between three types of column for this service. The new SMR packing marketed by Glitsch is the first packing developed specifically for liquid-liquid extraction service and is compared with a column packed with Raschig rings and a pulsed perforated plate column.
