摘要
INTENTION:The effect of different reaction conditions such as temperature,pH value,time,the concentration of Na+ ions and Pb2+ ions on the complexation capacity of carboxymethyl chitosan（CMCS） to Ca2+ions,were investigated.METHOD:In different reaction conditions,carboxymethyl chitosan reacted with saturated solution of calcirm chorde,produced carboxymethyl chitoxan calcium（CCC）.The Ca2+ions concentration of CCC was determined by atomic absorption spectrophotometer.RESULT:After 15 minutes,the complexation capacity of Ca2+ions to CMCS was to most in the room temperature at pH6.0.CONCLUSION:The complexation of Ca2+ions to CMCS has been influenced by the complexation capacity of CMCS to other cations in the reactions system.
INTENTION： The effect of different reaction conditions such as temperature, pH value, time, the concentration of Na^＋ ions and Pb^2＋ ions on the complexation capacity of carboxymethyl chitosan （CMCS） to Ca^2＋ ions, were investigated. METHOD： In different reaction conditions, carboxymethyl chitesan reacted with saturated solution of calcirm chorde, produced carboxymethyl chitoxan calcium （CCC）. The Ca^2＋ ions concentration of CCC was determined by atomic absorption spectrophotometer. RESULT： After 15 minutes, the complexation capacity of Ca^2＋ ions to CMCS was to most in the room temperature at pH6. 0. CONCLUSION： The complexation of Ca^2＋ ions to CMCS has been influenced by the complexation capacity of CMCS to other cations in the reactions system.
