SINGLE-STAGE AND TWO-STAGE SOLVENT EXTRACTION OF Tl(III) IN HOLLOW-FIBER CONTACTORS UNDER RECIRCULATION MODE OF OPERATION

Novel 90Sr–90Y generator system based on a pertraction through supported liquid membrane in hollow fiber contactor

“…(10 and the overall mass transfer coefficients determined from the slopes are listed in Table 4. As can be seen from , which is generally observed trend for extraction systems with D m » 1 [28]. , where b is a slope of the best fit line in Fig.…”

“…' R E is the removal efficiency per single pass of the feed stream, and K D is the overall mass transfer coefficient based on the donor phase [21,28].…”

“…The overall mass transfer coefficient in a SLM extraction system with closed-loop recirculation of both aqueous phases was determined experimentally using the equation [28]:…”

Supported liquid membrane extraction of 177Lu(III) with DEHPA and its application for purification of 177Lu-DOTA-lanreotide

“…In order to meet the high quality requirements (in terms of purity) prescribed for radiopharmaceuticals, re-circulating mode of operation or twostage solvent extraction systems are often applied [18,19].…”

Liquid-phase membrane extraction of targeted pesticides from manufacturing wastewaters in a hollow fibre contactor with feed-stream recycle

“…HF-LPME can be operated in a continuous flow mode or batchwise. If the specified degree of solute extraction cannot be achieved in a continuous flow HF-LPME process with a single pass of the feed stream through the contactor, the feed stream is recycled between the module and a mixed tank [16][17][18].…”
