摘要:
HPTLC was used to check for residues of benomyl, carbendazim, ethoxyquin and thiabendazole in apples and pears. The method used showed good precision with a percentage coefficient of variation of less than 5%; recoveries were always greater than 90%. The limits of determination using HPTLC were always at least four times lower than Italian statutory limits. Selectivity with respect to other matrix components was excellent for all fruit varieties tested. Comparison with HPLC confirmed the validity of the results.
