测定了在２５．０℃下，羧甲基甲壳素（ＣＭ－ＣＨ）及羧甲基壳聚糖（ＣＭ－ＣＨＯ）在纯水溶液及ＮａＣｌ水溶液中的特性粘数［η］。在纯水溶液中用Ｆｏｕｓｓ经验式关联实验数据得ＣＭ－ＣＨ及ＣＭ－ＣＨＯ的［η］分别为１１９７ｍＬ／ｇ，１２６２ｍＬ／ｇ；得出了０．０１ｍｏｌ／ＬＮａＣｌ溶液中ＣＭ－ＣＨ及ＣＭ－ＣＨＯ的［η］为２８３ｍＬ／ｇ和３６５ｍＬ／ｇ。讨论了ＣＭ－ＣＨ及ＣＭ－ＣＨＯ在纯水及加盐水溶液中的形态。
The intrinsic viscosity [η] of carboxymethyl chitin (CM-CH) and carboxymethyl chitosan (CM-CHO) in pure water and NaCl aqueous solution was measured at 25.0 ℃. The results showed that the [η] of CM-CH and CM-CHO were 1197mL / g and 1262mL / g, respectively. The experimental data of Fouss experiential correlation in pure water showed that CM-CH and CM- [Η] of 283 mL / g and 365 mL / g. The morphology of CM-CH and CM-CHO in pure water and saline solution was discussed.
