NOVELTY - Preparation of copper (Cu) aluminum (Al)-LDH/tin sulfide (SnS)/graphene oxide (GO) composite material comprises adding copper nitrate and aluminum nitrate into deionized water, stirring, adding ammonia water, continuously stirring and aging, washing and filtering, and drying; adding into mixed solution of triethanolamine and ethylene glycol, stirring, adding tin bromide (SnBr2), and stirring; adding sodium sulfide into deionized water, and stirring to form transparent solution; dropping into solution under nitrogen environment, transferring solution into centrifugal tube, centrifuging at high speed, using deionized water and absolute ethanol to wash, and vacuum drying; and adding graphene oxide into deionized water, sonicating for 1 hour to completely disperse, adding product of third step, stirring for 30 minutes, transferring solution into PTFE-lined reaction kettle, hydrothermal reacting, finishing reaction, using deionized water and ethanol to wash, and vacuum drying. USE - The method is used for preparing copper aluminum-LDH/tin sulfide/graphene oxide composite material for removing glyphosate. DETAILED DESCRIPTION - Preparation of copper (Cu) aluminum (Al)-LDH/tin sulfide (SnS)/graphene oxide (GO) composite material comprises adding copper nitrate and aluminum nitrate into deionized water, stirring for 30 minutes to completely dissolve, adding ammonia water to adjust pH of solution while stirring, continuously stirring and aging for 10 hours, washing and filtering for 3 times, and drying at 70 degrees C; adding into mixed solution of 4 ml triethanolamine and 20 ml ethylene glycol, stirring for 1 hour, adding tin bromide (SnBr2), and continuously stirring for 1 hour; adding sodium sulfide into deionized water, and stirring for 1 hour to form transparent solution; dropping into solution under nitrogen environment, transferring solution into centrifugal tube, centrifuging at high speed, using deionized water and absolute ethanol to wash for 3 times, and vacuum drying at 60 degrees C; and adding graphene oxide into deionized water, sonicating for 1 hour to completely disperse, adding product of third step, stirring for 30 minutes, transferring solution into PTFE-lined reaction kettle, hydrothermal reacting, finishing reaction, using deionized water and ethanol to wash for 3 times, and vacuum drying at 60 degrees C.
