Preparation of A New Functional Paper Using CMC/Cationic β-CD Self-assembly and Its Application in Water Treatment
(0) A new type of self-assembled functional paper was prepared by fixing cationic β-cyclodextrin(β-CD)onto carboxymethyl-cellulose(CMC)in water medium.Wastewater samples containing phenylamine were treated by the functional paper.The inclusion capability of CMC/cationic β-CD self-assembled fimctional fibre for phenolphthalein solution was determined.The physical properties of functional paper were also investigated.In addition,the treatment time,number of filtration layer and enrichment capabilities of the functional paper for wastewater containing phenylamine were investigated.The results showed that cationic β-CD can be fixed onto CMC successfully,paper properties such as bursting index,density and wet-tensile index increased by 6.7％,2.7％ and 519.3％ respectively compared with CMC paper,but dry-tensile index decreased by 5.2％.The higher the DS of CMC( at DS below 0.4)was,the better the paper properties were.The results also showed that the phenylamine in the effluent could decrease from 13.365 mg/L to 0.064 mg/L in 30 min when double layers of functional paper were used,representing a removal rate of phenylamine of up to 99.52％.
