Abstract Chitosan-polyanion complexes are used as coagulants for treating the extraction liquid of Carthamus tinctorius L.FT-IR analyses show electrostatic interaction between the chitosan-NH~+_3 and Carrageenan-SO~-_3 group is responsible for complex formation.The factors affect the coagulation efficiency are discussed such as the complexes of different polycation-polyanion and their complex type,complex ratio etc.The flocculation experiment shows that the coagulation efficiency was improved significantly by the complex of chitosan-Carrageenan.
