2Mix down at 20-30 ℃, stirred 2 hours, left standstill 5-12 hour, filter, spend deionised water 3 times, obtain magnalium hydrotalcite.
2. with TiCl
4Be dissolved in the HCl solution of 0.1-5mol/L concentration, then through diluting to such an extent that contain the pillaring solution that Ti concentration is 0.4-0.9mol/L.
3. the magnalium hydrotalcite that step 1 is obtained is according to the ratio formulated suspension of quality 1-5%, and the average grain diameter of magnalium hydrotalcite is the 5-50 micron, pillaring solution slowly is added dropwise to institute joins in the suspension, stirs while dripping.After stirring end, suspension is placed pressure vessel, under 0-5MPa pressure and 10-300 ℃ of temperature conditions, left standstill 0-48 hour respectively.Leach then, under 100-120 ℃ of condition, dry.
4. sample is placed muffle furnace, any under room temperature-860 ℃ condition or the heating of a plurality of temperature spot 1-2 hour, with the stove cooling, being ground to granularity is the 80-200 order.
5. the hydrotalcite with roasting is immersed in respectively under room temperature in zirconyl chloride solution, liquor argenti nitratis ophthalmicus, cerous nitrate solution or the gadolinium oxide solution of 0.01mol/L-0.5mol/L, soaks 1-48 hour, filters and takes out.
6. above sample was shone 1-60 minute oven dry under the microwave of 370W.
7. the hydrotalcite that step 6 is obtained places muffle furnace to heat 1-8 hour down in 300-400 ℃, makes sorbing material.
8. if imvite is dipped in the liquor argenti nitratis ophthalmicus in 5 set by step, add quality 5-10% formaldehyde, soaks after 1-48 hour, left standstill 5 hours in 70-90 ℃ of following lucifuge, to filter and take out, oven dry must contain the silver-colored sorbing material of simple substance.
The invention has the advantages that sorbing material can use at ambient temperature, result of use is good, removes copper and the plumbous good effect that has in the autonomic drug system, can reach the effect of degree of depth absorption, limit adsorption concentration 50ppb.
