Description
Technical field
The present invention relates to a kind of load lanthanum titanium dioxide arsenic fluorine altogether except adsorbing material and preparation method thereof, belong to Environmental science and technology field.
Technical background
Subsoil water arsenic fluorine coexists and is worldwide widely present, and is focus and the difficult point of international environmental studies. By 2014, China there are about 86,000,000 people and is in high fluoride area, 2890000 rural populatioies drink high arsenic water, and arsenic fluorine combined pollution phenomenon highlights, and High Concentration of Arsenic fluorine water coexists and the phenomenon of arsenic-fluoride poisoning all has been reported that in areas such as Xinjiang of China, Shanxi, the Inner Mongol, Guizhou. Long-term drink height arsenic fluorine water (arsenic > 10 μ g/L, fluorine > 1.5mg/L) may result in dental fluorosis, ostealleosis and multiple internal organs canceration etc., the arsenic fluorine how effectively to remove in subsoil water becomes the key issue that environmental area is urgently to be resolved hurrily.
Adsorption filtration is the mainstream technology of currently processed subsoil water arsenic fluoride pollution. Conventional adsorbing material includes activated carbon, ferrum oxide, aluminium oxide and titanium dioxide etc. Current iron-based adsorbing material is widely used in the removal of Arsenic Contamination in Groundwater, but it is very low to the clearance of fluorine. Recent studies suggest that that ferrum can increase the collaborative toxicity of arsenic, as the element that oxidoreduction is active, iron-based adsorbing material can dissolve release arsenic under anaerobic environment, causes the secondary pollution of subsoil water arsenic to threaten, and therefore needs the use of careful consideration iron-based adsorbent. Although arsenic fluorine is had certain adsorption by activated carbon and aluminium oxide, but adsorption capacity is difficult to practical requirement. This is due to natural groundwater pH many one-tenth alkalescence, with this understanding, can being removed by most material active adsorption for the arsenic being primarily present form with As (III), but the advantageous pH range of adsorbing material fluorine removal is generally 5～6, therefore natural water body arsenic fluorine is altogether except tool acquires a certain degree of difficulty.
In order to overcome now methodical deficiency, the present invention obtains load lanthanum composite titania material by specific binding in the way of oriented growth to titanium dioxide and lanthanum-oxides.
