| titleOfInvention | Lead ion enrichment material preparation process |
| abstract | The invention relates to a lead ion enrichment material preparation process which includes: adding phosphate solution and walnut shells which are cleaned, dried and powdered into methanol solution of tetramethoxysilane, mixing by stirring, forming by extruding the mixture, drying the formed mixture in a drying box, and performing air-isolated heat treatment in a resistance furnace so as to obtain a granular material; dissolving silver nitrate and glucose in water, adding the granular material with stirring, drying in the drying box directly after draining off filtrate, and heating to realize reduction so as to obtain a lead ion enrichment material. The lead ion enrichment material mainly comprises activated carbon and also comprises, by mass, 0.5%-2.5% of silver particles and 1%-5% of SiO2 particles. Lead ion in a water sample can be enriched by the lead ion enrichment material, and then the lead ion can be transferred into 25% of brine solution by soaking the lead ion enrichment material into the brine solution for at least ten hours. The lead ion enrichment material preparation process requires mild conditions and low cost and is convenient in operation and free of pollution. The lead ion enrichment material has good mechanical strength and chemical stability and can be reused. |
