Raw　Huai　Flos　Chrysanthemum　(HFC)　and　modified　HFC　(HFC@CO)　were　used　for　the　first　time　as　a　biosorbent　material　to　remove　cationic　dyes　Malachite　green　(MG)　and　Crystal　violet　(CV),　and　anionic　dyes　Sunset　yellow　(SY),　Lemon　yellow　(LY),　and　Carmine　(CM),　at　different　temperatures　(5-50　degrees　C).　The　highest　removal　rates　(R)　for　dye　adsorption　were　observed　at　low　temperature　(5　degrees　C)　and　room　temperature　(20　degrees　C).　At　high　(500　mg　L-1)　dye　concentration,　adsorption　was　completed　within　one　minute,　but　the　time　required　to　reach　adsorption　equilibrium　was　longer　than　at　the　low　(20　mg　L-1)　concentration.　The　experimental　data　fitted　very　well　to　the　Langmuir　model　and　the　values　of　the　maximum　adsorption　capacity　for　SY,　LY,　CM,　CV,　and　MG,　were　481.41,　507.23,　141.78　mg　g(-1),　526.32,　and　769.23　mg　L-1,　respectively.　The　adsorption　data　fit　well　to　a　pseudo-second-order　kinetic　model.
