ABSTRACT
Our study was undertaken to compare the behaviour and properties of two new ketoimine sorbents with a commercial sorbent C-18. The sorbents were used to concentrate the endocrine-disrupting compounds (EDCs) in the water, by the use at solid phase extraction (SPE). EDCs were analyzed by high performance liquid chromatography (HPLC) coupled to UV detection. The residues of bisphenol A, bisphenol A diglycidyl ether, bisphenol F and bisphenol F diglycidyl ether in the water having contact with polycarbonate plastic have been determined. The applicable concentration range was 0.5 to 100 µg/l in water samples. Detection limits were of about 0.20 µg/l for BPA and BPF, and 0.50 µg/l for diglycidyl ether derivatives. The recovery of bisphenol A introduced into water ranged from 93.3% to 97.0%, of BPF from 91.6% to 95.9%, of BADGE from 82.0% to 86.4%, and of BFDGE from 79.7 to 82.5%. The proposed method is simple and sensitive, and thus well suited for analysis of ECDs in the water.
