Novel micro/nano trivalent silver iron compound synthesizing method

Abstract

The invention relates to a novel micro / nano trivalent silver iron compound synthesizing method, which comprises the following steps of: (1) weighing silver-containing reactants according to a ratio, fully grinding the silver-containing reactants and uniformly mixing the grinded materials; (2) adding de-ionized water into the mixed material to stir the mixed material into a flowing deformation state; (3) keeping the mixture constant for a certain time; and (4) filtering the mixture, washing the obtained product clean with pure water and washing away un-reacted materials to obtain a novel micro / nano trivalent silver iron compound. In a flowing deformation phase system, solid particles are uniformly distributed in fluid and tightly contact one another, and the surfaces of the solid particles can be effectively used, so the reaction is more complete, the product recovery rate is high and the synthesis efficiency is high; the ratio of the product to the reactor volume is very high, the mass production of wastes is avoided, and thus, the method is favorable for environment protection and is a green production process with the advantages of high efficiency, energy conservation, cost conservation and environmental friendliness; and all parts in the fluid have high exchangeability and stable heat transmission and mass transfer, the partial overheat can be avoided and the temperature is easy to control, so homogeneous granular micro / nano materials can be obtained.

Description

technical field [0001] The invention belongs to the field of micro-nano materials and inorganic green chemical synthesis, and specifically relates to a method for efficiently synthesizing micro-nano trivalent silver ion compounds by a soft chemical method. Background technique [0002] Microorganisms such as harmful bacteria, fungi and viruses in nature are the main causes of human infection and disease induction. The Black Death, which killed one-third of the European population in the mid-14th century AD, and the flu, which killed more than 20 million people worldwide in the early 20th century. In recent years, with the frequent exchanges of human activities and the increase of population density, not only the traditional microorganisms caused diseases increased, but also new microorganisms caused epidemics. Pathogenic Escherichia coli 0-157 nationwide in Japan in 1995, mad cow disease in the UK before the 20th century, foot-and-mouth disease in the United States, anthrax...
