Abstract:

Zinc is an essential trace element, zinc content in human body is 1.4~2.3g, is widely distributed in various tissues, including skeletal and skin are more, the nutritional status of zinc content in hair Znn reflect the long-term supply of dietary zinc level and human zinc. Using the high pressure nitrifying pot method and wet method and treatment of samples were determined in natural Huazi Mushroom samples Zn element content. High pressure nitrifying pot method relative standard deviation of Zn element is 5.82%; Wet method to determine the relative standard deviation of Zn elementt is 4.81%. Visible high pressure nitrifying pot method and treatment of samples of precision of the measuring precision and wet processing samples are relatively low. By comparison, high pressure nitrifying pot method specific humidity method to deal with the sample good measuring precision, higher accuracy, and the measurement process to save time.
