  • (PDF) Solid phase extraction of zinc with octadecyl

    The relative standard deviation of zinc for ten replicate extraction of 10 μg zinc from 1000 mL samples was 1.2%. The limit of detection of the proposed method was 14 ng of Zn2+ per 1000 mL.

  • Phyto-extraction of zinc, lead, nickel, and cadmium

    The results showed that if the SFs are calculated based on the BCF of lead—as the fraction denominator—the SF values are obtained 7.83, 3.6, 2.27, and 1 for cadmium, nickel, zinc, and lead, respectively, which shows the tendency of A. retroflexus for heavy metal extraction is in ascending order for lead, zinc, nickel, and cadmium, respectively.
