| Abstract: | In a borate buffer mediun of pH 8.5,zinc in hair was detemined by spectrometry with the reagent 1-(2-pyridylazo)-2-naphthol-6-sulphonic acid.The maximum absorbance was at 530 nm with apparent molar absorption of 1.14×104L/(mol·cm).The Beer′s law was obeyed in the range of 0 to 21 μg/(25 mL).The RSD was 0.86% to 1.3%,and recoveries were 97.0% to 99.7%. |
