The activated clay was modified by using cetyltrimethyl ammonium bromide as surfactant. Furthermore,as-modified activated clay recombined chitosan to synthesize activated clay / chitosan composites readily by one-step method. The obtained composite was characterized by infrared spectrometer( FTIR),thermogravimetric analyzer( TGA),X-ray diffraction instrument( XRD) and transmission electron microscopy( TEM) for studying the structure,thermal stability performance,morphology. The absorption properties of acti...
