海藻酸钠/多壁碳纳米管复合水凝胶球的制备及对次甲基蓝的吸附研究
MWNTs in Sodium Alginate Gel Beads: Preparation and Adsorption towards Methylene Blue
【摘要】 以海藻酸钠(SA)、多壁碳纳米管(MWNTs)为主要原料,通过溶胶-凝胶法制备复合水凝胶球,研究了微球对次甲基蓝(MB)溶液的吸附脱色效果。结果表明:当海藻酸钠溶液的加入量为2%、多壁碳纳米管的含量为0.15%时,120h后微球对次甲基蓝的吸附率可达83.46%。
【Abstract】 Using sodium alginate(SA) and multi-walled carbon nanotubes(MWNTs) as raw materials,SA/MWNTs composite gel beads were prepared by sol-gel method.The adsorption of the gel beads towards methylene blue(MB) was studied.Experimental results show that the adsorption ratio towards methylene blue can reach 83.46% when the mass fraction of SA is 2% and the content of MWNTs in the gel beads is 0.15% after 120h.
