Chitosan（CS） has a large number of hydroxyl and amino groups,which can provide more active sites for adsorption of pigment pollutants,but it was easy to dissolve in acidic conditions.MXene could provide support sites for CS,thereby constructing a new type of MXene@CS composite material.A new type of Ti3C2TX@CS organic-inorganic composite was synt-hesized and applied in the removal of Congo red（CR）.The Ti3C2TX@CS composite was proven to be physically compounded through the micromorphology,crystal structure and surface functional group analysis data.The experimental results showed that the decolorization rate of CR solution（500 mg/L） by synthesized Ti3C2TX@CS could exceed 99% at Ti3C2TX@CS dose of 30 mg,pH of 9,and reaction time of 30 min and the temperature range at 25~60 ℃.The experimental results and the change of Ti3C2TX@CS potential before and after the reaction were used to infer the Ti3C2TX@CS to Congo red.The removal mecha-anism is the action of electrical neutralization and adsorption bridging.
Key words： Ti3C2TX@CS; Congo red（CR）; flocculant; decolorization rate
