| titleOfInvention | Preparation method and application of nano zero-valent iron composite material |
| abstract | The invention relates to a nano zero-valent iron composite material and a preparation method thereof. The preparation method comprises the steps of firstly preparing the corn straw biochar, soaking and modifying the biochar by using nitric acid, washing to be neutral, and drying for later use; FeSO is reduced by liquid phase reduction method in nitrogen environment 4 ยท7H 2 Reducing O into simple substance iron, and loading the simple substance iron on the biochar; and carrying out solid-liquid separation on the solution after the reaction to obtain the biochar loaded nano zero-valent iron composite material. The material is used for removing lead in underground water, the problems of agglomeration and activity reduction of nano iron particles in the using process are solved, secondary pollution is avoided in the repairing practice, and the removal rate can reach over 90% by simulating the lead removal experiment in the underground water in the constructed organic glass simulated reaction column. |
