Embodiment 1
[0007] Embodiment 1:1.35g lithium hypochlorite, 1.65g bis(acetylacetonate) beryllium, 140ml deionized water, join volume and be that in the sealable reactor of 500ml, stir and mix evenly, the weight concentration of this aqueous solution is 2.1%, times Lithium chlorate: the weight ratio of bis(acetylacetonate) beryllium=1:1.2; adding deionized water to wash to neutrality, drying at 103°C to remove moisture, and then sieving 2.75g activated carbon of -200 mesh to +400 mesh standard sieve, 3.75g carnallite, 4.75g dolomite, 5.75g calcite, 6.75g sodium saltpetre, 7.75g dolomite, weight of lithium hypochlorite and bis(acetylacetonate)beryllium (3g): weight of porous material (31.5g) =1:10.5, heat up to 36°C, continue to stir and react for 3.2h, filter, dry at 103°C and obtain 31g of pore-enlarging modified carrier; in a 500ml ultrasonic reactor, put 31g of pore-enlarging modified carrier, and then add 3.25 gβ-Hydroxyethyl dimethyl ammonium lauryl sulfate dissolved in 100ml of deion...
Embodiment 2
[0008] Embodiment 2: 0.24g lithium hypochlorite, 0.36g bis(acetylacetonate) beryllium, 10ml deionized water, join volume and be that in the sealable reactor of 100ml, stir and mix evenly, the weight concentration of this aqueous solution is 5.7%, times Lithium chlorate: the weight ratio of bis(acetylacetonate) beryllium=1:1.5; add deionized water to wash to neutrality, dry at 103°C to remove moisture, and then sieve 1.45g of activated carbon of -200 mesh to +400 mesh standard sieve, 1.65g carnallite, 1.85g dolomite, 2.05g calcite, 2.25g sodium saltpeter, 2.45g dolomite, weight of lithium hypochlorite and bis(acetylacetonate)beryllium (0.6g): weight of porous material (11.7g )=1:19.5, heat up to 48°C, continue stirring for 5.8h, filter, dry at 105°C and obtain 11.5g of pore-enlarging modified carrier; put 11.5g of pore-enlarging modified carrier into a 100ml ultrasonic reactor, Then add 2.2g of β-hydroxyethyl dimethyl ammonium dodecyl ammonium sulfate dissolved in 26ml of deion...
