| titleOfInvention | Ferrous modified selenium sol for inhibiting cadmium and arsenic accumulation of rice and preparation method and application thereof |
| abstract | The invention discloses a ferrous modified selenium sol for inhibiting the accumulation of cadmium and arsenic in rice and a preparation method and application thereof. The preparation method of the ferrous modified selenium sol comprises the following steps: (1) dissolving an iron-containing compound and a selenium-containing compound into water to obtain a mixed solution containing iron and selenium; (2) adding a reducing agent into the mixed solution, stirring until no precipitate is generated, adding carbonate, stirring until no precipitate is generated, filtering, taking the precipitate, and washing to obtain a selenium simple substance and a ferrous carbonate precipitate; (3) adding an emulsifier into the citric acid buffer solution to obtain an emulsified citric acid buffer solution; (4) adding the selenium simple substance and ferrous carbonate precipitate into an emulsified citric acid buffer solution to obtain a sol system; (5) and (3) evaporating and concentrating the sol system, and adjusting the pH value to 4.5-8.5 to obtain the ferrous modified selenium sol for inhibiting the accumulation of cadmium and arsenic in rice. The ferrous modified selenium sol prepared by the invention can effectively reduce the cadmium and arsenic content of rice, thereby realizing the safe production of rice. |
