摘要

Abstract

The silk sericin is the main residue in silk production and it is found to be a low cost and efficient biosorbent.In this study

sericin was characterized with various techniques including SEM(scanning electron microscope)

XRD

physisorption

FTIR(Fourier transformed infrared spectroscopy) and XPS(X-ray photoelectron spectroscopy).The nitrogen content of sericin was ca.8.5 mmol·g

-1

according to elemental analysis.Dye adsorp-tion by sericin biosorbent was investigated with the acid yellow(AY)

methylene blue(MB) and copper(II) phthalocyanine-3

4'4″4'″-tetrasulfonic acid(CuPc) dyes from water.Sericin displayed large capacity for AY and CuPc adsorption with adsorption capacities of respectively 3.1 and 0.35 mmol·g

-1

but it did not adsorbed methylene blue dye.This selectivity is due to the basicity of amide groups in sericin biosorbents.
