  Abstract

In this study, polysulfone-Escherichia coli biomass composite fiber (PSBF) was prepared by spinning the suspension of PS and E. coli biomass and amine-methylated PSBF (AM-PSBF) was fabricated through the methylation of amine groups in PSBF. As comparing the adsorption characteristics of basic dye, Basic Blue 3 (BB3) by the PSBF and AM-PSBF, the effect of the methylation of amine groups on BB3 adsorption was confirmed. pH edge experiments showed that the BB3 uptake of PSBF and AM-PSBF increased as pH was increased and the BB3 uptake of AM-PSBF was higher than that of PSBF at the same pH. Both of PSBF and AM-PSBF was reached at equilibrium within 5 h and kinetic experimental data were well fitted by the pseudo-firstorder kinetic model. By the Langmuir model, the maximum adsorption capacities of PSBF and AM-PSBF at pH 8 were evaluated to be 28.9 and 20.7 mg/g, respectively. The maximum adsorption capacity of AM-PSBF was enhanced 1.4 times comparing that of PSBF. These results indicate that the methylation of amine groups in PSBF leads to the improvement of BB3 adsorption capacity. In addition, the results of desorption experiments revealed that AM-PSBF was repeatedly reusable.
