Chitosan isoelectric point
Web14 hours ago · The lowest solubility was detected around pH = 4, near the isoelectric point of CMCS (pH = 4.5) [22], where the charges of NH 3 + and COO − groups are equal (Table 1) [36]. According to the pKa values of CMCS, when pH < pKa ,COOH , the carboxylic acid will ionize to COO − and is dissolved in water.
