“…1 indicated that although dihexyl ether can only extract 3 analytes (BPAF, TMBPA and TBBPA), undecane facilitated the extraction of 4 analytes (BPAF, TMBPA, TCBPA and TBBPA). Because the addition of TOPO into the membrane liquid could usually enhance the extraction efficiency of weak organic acids, 29 undecane and dihexyl ether dissolved with 5% (m/v) TOPO were further tested as liquid membranes. As shown in Fig.…”

“…A number of analytical methods have been reported for determination of phenoxyacid herbicides in different matrices using high-performance liquid chromatography HPLC [3][4][5], gas chromatography GC-MS [6][7][8][9][10][11], capillary electrophoresis [12][13][14][15][16] and micellar electrokinetic chromatography [17]. Because of the complex structure of matrix and the presence of pesticides in small quantities, different procedures for extracting and preconcentration of pesticides from samples are needed to develop.…”
