“…This acid is the most quoted in literature for use as the acceptor solution. 13,[26][27][28][29] The drug-protein interactions are usually responsible for the low recovery values. Because of this interaction, it is common to add an organic solvent in the donor solution (sample) to suppress the drug-protein bonds.…”

“…Thus, the hollow fiber based LPME is a reliable and robust technique which can provide high enrichment and low limits of detection. To date, many works published have successfully applied the hollow fiber based LPME for extraction of several different classes of drugs from various matrices [24][25][26][27]. Final analysis of extraction solutions has been reported with CE [23], HPLC [28], GC-MS [29], and LC-MS [30].…”

“…O ajuste do pH resulta em uma maior razão de distribuição e garante elevados fatores de enriquecimentos e valores de recuperação do analito de interesse. 36 Ajustes no pH podem aumentar a eficiência da extração, uma vez que tanto o equilíbrio de dissociação quanto a solubilidade de ácidos e bases são diretamente afetados pelo pH da amostra. 37 …”
