| Abstract |
In this study, the influence of surfactants (SDS, TX100 and CTAB) to modify surface polarity of graphene
oxide adsorbent is proposed for the extraction of b-carotene and total carotenoids from fruit juice
samples. Under the optimum conditions based on simultaneous ultrasound-assisted surfactant surface
decorated graphene oxide and ultrasound-assisted dispersive solid-phase microextraction (UAD-SPME)
prior to UV-vis spectrophotometry and HPLC, the calibration curve was in the range of 1.0–6.0 mg L1
(R2 ¼ 0.9999), the limit of detection was 0.04 mg L1 and the limit of quantification was 0.12 mg L1.
The relative standard deviations were 1.98% and 2.38% for intra-day and inter-day analysis, respectively.
For real sample analysis, the contents of total carotenoids were found in the range of 2.37–65.02 mg bcarotene
per L, while that of b-carotene analyzed by HPLC was rather reasonable (0.37–46.82 mg L1).
The recovery tests yielded satisfactory results, ranging between 93.00% and 109.5%. Therefore, the
developed method is a green way for the UAD-SPME of b-carotene and total carotenoids from fruit juices. |
