Abstract

The interaction of chitosan (CTS) and alizarin red (AR) at pH = 5.0 was studied by absorption spectra. The influence of the molar ratio of AR/CTS, different concentrations of NaCl and deacetylation degrees of CTS on the interaction between chitosan and alizarin red was investigated. The maximum binding numbers (N_e = 4.78 * 103, N_c = 4. 73 * 103) were obtained by spectroscopic experiment and theoretical model, respectively. The experimental value is consistent with the theoretical value.

Key words: CHITOSAN, ALIZARINE RED, IR, SODIUM CHLORIDE, INTERACTIONS
