The accuracy and precision were evaluated using Standard Reference Material (rice flour NIST 1568a), and yielding relative standard deviation below 5%. The paired t-test showed good agreement within 95% confidence values. The detection limits (3σ) of Mn and Zn were 5.1 and 2.2 mg kg-1, respectively. The proposed method proved to be effective when used to determine Mn and Zn in commercial samples of rice without go by stage of decomposition.Submitted by Edileide Reis (leyde-landy@hotmail.com) on 2014-07-16T12:02:50Z No. of bitstreams: 1 Alete Paixão Teixeira.pdf: 271728 bytes, checksum: 2784ac76d40631f89dab38d47a96afd2 (MD5)Made available in DSpace on 2014-07-16T12:02:50Z (GMT).
