| titleOfInvention | Silver-silver halide load iron nano-mineral composite material and preparation method |
| abstract | The present invention provides a kind of silver-silver halide load iron nano-mineral composite material and preparation methods, are related to environmental wastewater pollution control field.The preparation method includes: that iron nano-mineral is added into silver nitrate solution, obtains the first mixed liquor；It is added into the first mixed liquor for making silver nitrate generate the alkali halide solution of silver halide precipitation completely, obtains the second mixed liquor；Hole trapping agents are added into the second mixed liquor, photoreduction is carried out the part silver halide with ultraviolet light and generates elemental silver, obtains third mixed liquor；It is freeze-dried after carrying out multiple centrifuge washing to third mixed liquor.The preparation method is at low cost, and cyclic utilization rate is high, can reduce cost for wastewater treatment.Composite material obtained has many advantages, such as uniform particle sizes, reunites less, good dispersion, can be effectively removed organic pollutants under visible light, and reuses number height, and iron the amount of dissolution is low, avoids secondary pollution, is a Xiang Huanbao, economic technology. |
