| titleOfInvention | A kind of salicylic acid chelating silica gel heavy-metal adsorption material and preparation method thereof |
| abstract | Silica gel load aminated compounds disclosed by the invention, salicylic acid and using salicylic acid as main adsorption function group, dual-functional group composite adsorbing material using formaldehyde as bridge, the invention also discloses its preparation method, using 20 150 mesh Bio-sils as inorganic rigid skeleton, humidified, pickling, hydration, alkylation, bonding aminated compounds, grafting salicylic acid, obtain a kind of organic/inorganic composite adsorbing material of dual-functional group.Aminated compounds prepared by the present invention/material silica gel composite heavy metal ion has an excellent absorption property, then by be bonded salicylic acid on the premise of adsorption capacity is further increased the sorbing material to Fe 3+ There is the effect that selection is adsorbed.And the material can be recycled for multiple times after regeneration.Sorbing material preparation technology is simple, easily realizes industrialization, without using toxic solvent, raw material sources are extensive, can be applied to the absorption, separation, enrichment of heavy metal in water, realize heavy metal-polluted waste water recycling device, significant in terms of environmental protection. |
