Abstract

In our investigation we proposed a quantitative analysis system for manganese (II) cation in NaCl matrix by means of solid state electron spin resonance (ESR) spectroscopy. The signal is due to Mn2+, which results in six hyperfine splitting of equivalent intensities owing to the nuclear spinI=5/2 of Mn nuclei. In typical NaCl matrix of food, however, the Mn2+signals exhibit non-equivalent hyperfine intensity with relatively much higher intensity in the central groups.<BR>Mn2+contents in the NaCl matrix of the foods were determined by ESR. These studies reported Mn2+content in the food, for example, Uji-cha (maccha); 195.00μg/g and red Hibiscus (Hibiscus sabdariffa)-cha; 216.00μg/g. On as hand, Mn2+contents in the drinks were determined Uron-cha in the pet-bottle, 0.900μg/mL, and Beer made from barley, 0.082μg/mL.
