| titleOfInvention | Application of the porous silica in terms of metal filtration |
| abstract | The invention belongs to inorganic material application fields, and in particular to application of the porous silica in terms of metal filtration.The silica is made by following step：1) plant organ or algae are cleaned, removes stone cleaning and other impurities；Wherein described plant organ or algae dioxide-containing silica are more than the 1% of dry weight, and the clear water is less than the water of 100usv/cm for conductivity；2) it drains and oxygen is passed through in 500 degrees Celsius of ashing furnace and is constantly stirred；And pass through the oxidation of itself and generate heat, it maintains 450 600 degrees Celsius and obtains plant ass in 14 hours；3) with dilute hydrochloric acid washing plant ass removal metal impurities；A concentration of 1 5mol/L of dilute hydrochloric acid, dosage are 8 40L/kg plant ass.4) clear water cleans the porous silica that can obtain high-specific surface area.The present invention, to the absorption property higher of polar molecule, and can so that use cost is extremely low than simple activated carbon with regenerated adsorption capacity. |
