TiO2 nanotubes :A novel solid phase extraction adsorbent for the sensitive determination of nickel in environmental water samples
摘要:
A novel method was developed for the sensitive determination of nickel in environmental water samples by using TiO2 nanotubes,a new nanomaterial,as solid phase extraction absorbent.In general,TiO2 nanomaterials were often used for catalytic degradation of pollutants in environmental field,and only a very few application in environmental analytic chemistry.In present work,TiO2 nanotubes was firstly used for the enrichment of nickel and the factors would influence the preconcentration performance were optimized.Under the optimal conditions,TiO2 nanotubes exhibited its good enrichment capacity for nickel and the detection limit of the proposed method was 1 ng mL-1.The proposed method was validated with real water samples,and excellent results were obtained with the spiked recoveries in the range of 94.4-99.2%,respectively.
