| 摘 要： | 本文探索研究了氧化淀粉替代海藻酸钠的可能性,系统考察了制备条件对氧化淀粉性能的影响,包括反应温度、pH值、淀粉乳浓度、氧化剂用量等因素及其各种条件下的羧基含量。实验表明,随着pH值的降低,淀粉乳浓度的增加,氧化剂用量的增加,羧基含量有所增加。温度影响反应速度,温度对羧基含量影响不显著,考察了自制备氧化淀粉的成膜可行性。

| Abstract: | The probability of the oxidation starch substituting the alginate is studied in this paper. The preparation conditions, such as temperature, pH, starch breast concentration, oxidant dosage and carboxyl content are investigated. The experiment indicates that with the decreasing of pH and increasing of the starch breast concentration and oxidant dosage, carboxyl content is increased. The temperature influences the rate of reaction but there are not marked effects on carboxyl content. |
