Embodiment 1

[0021] At a temperature of 25°C, the concentration is 0.5mmol L -1 Selenium dioxide with 2mmol·L -1 Mix 2ml each of vitamin C, stir until brick red nano-selenium is produced, then add 1mmol·L -1 2ml of selenocystine, fully stirred and left to react for 48 hours, the brick red color in the solution disappeared, and a uniform red biopolymer nano-selenium composite film spontaneously formed at the bottom of the container.

Embodiment 2

[0023] At a temperature of 15°C, the concentration is 1.0mmol L -1 Selenium dioxide with 4mmol·L -1 Mix 2ml each of vitamin C, stir until brick red nano-selenium is produced, then add 2mmol·L -1 2ml of selenocystine, fully stirred and left to react for 48 hours, the brick red color in the solution disappeared, and a uniform red biopolymer nano-selenium composite film spontaneously formed at the bottom of the container.

Embodiment 3

[0025] At a temperature of 35°C, the concentration is 0.5mmol L -1 Sodium selenite with 2mmol·L -1 Mix 2ml each of vitamin C, stir until brick red nano-selenium is produced, then add 1mmol·L -1 2ml of selenomethionine, fully stirred and left to react for 24 hours, the brick red in the solution disappeared, and a uniform red biopolymer nano-selenium composite film spontaneously formed at the bottom of the container.

Abstract

The invention discloses a preparing method of biological high polymer nanometer selenium complex film, which comprises the following steps: mixing selenite or selenious anhydride and vitamin C; reacting until generating erythrine nanometer selenium; adding amino acid incorporated selenium; placing till erythrine disappearance; forming red biological high polymer nanometer selenium complex film at the bottom of vessel. This invention belongs to nanometer material and biological active material mixed type complex film, which can be used to health care, photoelectric material, biosensor and electrochemical catalytic reaction domain.

Description

Technical field: [0001] The invention relates to a preparation method of a biopolymer nano-selenium composite membrane. Background technique: [0002] In 1973, the World Health Organization (WHO) announced to the world that selenium is an essential trace element in human and animal life, and selenium supplementation can effectively prevent various diseases. According to the disclosure of the World Health Organization, there are currently about 2 billion people in the world (200 million people in China) living in a selenium-deficient environment. Selenium supplementation can effectively prevent and treat a variety of diseases, but a notable feature of selenium is the narrow range between its nutritional and toxic measurements, and the beneficial effects of selenium often depend on higher intakes, so its effective It is difficult to control the amount of use. For many years, people have been studying low-toxic and high-efficiency selenium products. Compared with inorganic sel...
