Through condition optimization, HMImT shows outstanding extraction capacity (Pd 0.54 mmol/g, Pt 0.14 mmol/g, Rh 0.82 mmol/g) and high extraction percentage to palladium (99.4%), platinum (99.8%), rhodium (99.6%) respectively.
The extraction results revealed the presence of neutral donors 2- 2-aminoethyl) pyridine shifts the extraction percentage curves towards higher pH region, indicating a synergistic effect of this donors on extraction of UO2- 2-aminoethyl the studied Schiff base (I).
Under the optimal conditions, the proposed method presented high enrichment factor of 193, an extraction percentage of 96.5, a detection limit of 0.0079 µg L−1 and a relative standard deviation (RS D%) of 1.63%.
Based on the design, the optimal conditions for obtaining higher extraction were extraction time 35 min, cycle ranging from 0.44 to 0.48 s−1, percentage amplitude ranging from 10to14%4%, and solid liquid ratio 10.
The results indicated that the extraction process was exothermical and the extraction percentage of Nd III) by IL-1 was the highest among the PFILs investigated.
Furthermore, F-18-labeled compound BMS747158 (F-BMS) is considered another high potent tracer for myocardial flow imaging as it shows a first-pass extraction percentage exceeding 90% [ 13, 14].
As a result, the low extraction percentage of manganese is an attractive advantage of this process.
The extraction percentage of copper was obtained as more than 99% under these conditions.
Although the extraction percentage was greater for Cl than for S during early leach cycles (< 7 months), overall amount of S extracted was higher, especially for CCPW (DP 1) columns.
But even high extraction costs can be economically viable because of the soaring value of fuel.
