采用溶液共混的方法,制备了一系列不同比例植酸改性细菌纤维素以及植酸改性含环氧基细菌纤维素的共混膜,用红外光谱对其结构进行了表征,并对其润湿性能、力学性能和Pb2+吸附及重复吸附性能进行分析。结果表明:以含环氧基团的细菌纤维素进行植酸改性,润湿性能良好,力学性能提高,且Pb2+吸附性能得到改善,最大吸附量为74.14mg/g,可多次重复使用。
A series of phytic acid modified bacterial cellulose and phytic acid modified epoxy-containing bacterial cellulose blend films with different content of phytic acid were prepared by solution method.The obtained blend films were characterized by FT-IR and the wetting property,mechanical property and lead ion adsorption and repeat adsorption property behavior were also studied.The results showed that epoxy-containing phytic acid modified bacterial cellulose had good wetting property,better mechanical property and improved lead ion adsorption property.The maximum adsorption capacity was 74.14mg/g,and it can be used repeatedly.
