Embodiment 1
[0013] Add 1g of montmorillonite to 100mL of β-cyclodextrin aqueous solution, wherein the concentration of β-cyclodextrin is 2g / L, place the mixture in a 30°C water bath for stirring, the stirrer speed is 2000r / min, and the stirring time is 6h , to obtain a montmorillonite / cyclodextrin suspension, and centrifuge the suspension at a speed of 3000 r / min for 10 min. The supernatant was removed, and the precipitate was dried in an oven at a drying temperature of 80° C. for 10 hours to obtain a montmorillonite sample containing β-cyclodextrin between layers. Add 0.2 g of the obtained sample into 100 mL of wastewater containing organic dyes, stir in a water bath at 30 °C for 2 h at a speed of 1500 r / min, take the supernatant after the solution is static and stratified, measure its COD value and absorbance value, and calculate its COD removal The rate reaches 71.3%, and the chroma removal rate reaches 98.6%.
Embodiment 2
[0015] Add 1g of montmorillonite to 100mL of α-cyclodextrin aqueous solution, wherein the concentration of α-cyclodextrin is 2g / L, place the mixture in a 30°C water bath for stirring, the stirrer speed is 2000r / min, and the stirring time is 6h , to obtain a montmorillonite / cyclodextrin suspension, and centrifuge the suspension at a speed of 3000 r / min for 10 min. The supernatant was removed, and the precipitate was dried in an oven at a drying temperature of 80° C. for 10 hours to obtain a montmorillonite sample containing α-cyclodextrin between layers. Add 0.2 g of the obtained sample into 100 mL of wastewater containing organic dyes, stir in a water bath at 30 °C for 2 h at a speed of 1500 r / min, take the supernatant after the solution is static and stratified, measure its COD value and absorbance value, and calculate its COD removal The rate reaches 68.6%, and the chroma removal rate reaches 98.1%.
Embodiment 3
[0017] Add 1g of montmorillonite to 100mL of β-cyclodextrin aqueous solution, wherein the concentration of β-cyclodextrin is 2.5g / L, place the mixture in a water bath at 30°C for stirring, the stirrer speed is 2500r / min, the stirring time After 7 hours, the montmorillonite / cyclodextrin suspension was obtained, and the suspension was centrifuged at a speed of 3500 r / min for 15 minutes. The supernatant was removed, and the precipitate was dried in an oven at a drying temperature of 90° C. for 10 hours to obtain a montmorillonite sample containing β-cyclodextrin between layers. Add 0.2 g of the obtained sample into 100 mL of wastewater containing organic dyes, stir in a water bath at 35 °C for 2 h at a speed of 1500 r / min, take the supernatant after the solution is static and stratified, measure its COD value and absorbance value, and calculate its COD removal The rate reaches 72.1%, and the chroma removal rate reaches 98.9%.
