Embodiment 1
[0027] 1) First put 20g of attapulgite in a 250ml Erlenmeyer flask, add 1g of cationic gemini surfactant 12-2-12, 20ml of 1mol / L hydrochloric acid, and 80ml of deionized water, seal the bottle, Put it into an incubator at 60° C., set the rotation speed at 200 rpm, and react for 3 hours.
[0028] 2) Take the mixture in step 1) out of the incubator, put it into a microwave oven, and set the microwave intensity to 400W for 3 minutes.
[0029] 3) Filter the mixture in step 2) through a Buchner funnel, and rinse repeatedly with deionized water until the eluent does not contain Br - So far, available AgNO 3 Solution titration test.
[0030] 4) Dry the filtered solid in step 3) in an oven at 80°C.
[0031] 5) Activate the dried solid in step 4) at 100°C for 1 hour.
[0032] 6) After the soil sample obtained in step 5) is subjected to mortar and sieve treatment, a microwave-organically modified attapulgite is obtained. The modified soil samples were analyzed by FTIR, XRD, TGA, et...
Embodiment 2
[0034] 1) First, put 30g of attapulgite in a 250ml Erlenmeyer flask, add 1.5g of cationic gemini surfactant 12-2-12, 30ml of 1mol / L hydrochloric acid, and 100ml of deionized water, and seal the bottle , put into an incubator at 60°C, set the rotation speed at 200rpm, and react for 5 hours.
[0035] 2) Take the mixture in step 1) out of the incubator, put it into a microwave oven, and set the microwave intensity to 500W for 4 minutes.
[0036] 3) Filter the mixture in step 2) through a Buchner funnel, and rinse repeatedly with deionized water until the eluent does not contain Br - So far, available AgNO 3 Solution titration test.
[0037] 4) Dry the filtered solid in step 3) in an oven at 75°C.
[0038] 5) Activate the dried solid in step 4) at 100°C for 2 hours.
[0039] 6) After the soil sample obtained in step 5) is subjected to mortar and sieve treatment, a microwave-organically modified attapulgite is obtained. The modified soil samples were analyzed by FTIR, XRD, TGA...
Embodiment 3
[0041] 1) First put 25g of attapulgite in a 250ml Erlenmeyer flask, add 1.2g of cationic gemini surfactant 12-2-12, 25ml of 1mol / L hydrochloric acid, and 90ml of deionized water, and seal the bottle , put into an incubator at 50°C, set the rotation speed at 200rpm, and react for 4 hours.
[0042] 2) Take the mixture in step 1) out of the incubator, put it into a microwave oven, and set the microwave intensity to 300W for 5 minutes.
[0043] 3) Filter the mixture in step 2) through a Buchner funnel, and rinse repeatedly with deionized water until the eluent does not contain Br - So far, available AgNO 3 Solution titration test.
[0044] 4) Dry the filtered solid in step 3) in an oven at 70°C.
[0045] 5) Activate the dried solid in step 4) at 100°C for 1.5 hours.
[0046] 6) After the soil sample obtained in step 5) is subjected to mortar and sieve treatment, a microwave-organically modified attapulgite is obtained. The modified soil samples were analyzed by FTIR, XRD, TGA...
