卡拉胶中钾离子含量的测定──离子选择电极法

钾离子在K型卡拉胶中的含量直接影响凝胶强度及凝固点，并影响卡拉胶应用产品的泌水性。采用离子选择电极分析法，再配以适合的总离子强度调节溶液，可避免干扰，快速准确地测定卡拉胶中钾离子的含量。

Content of potassium ion in the Kappa - Carrageenan directly influence on condensation point the strength and diffusion water of Carrageenan gel. The method of Ion - selective electrode companied with special solution can avoid effectively interfereing when measurting and exacttly measure content of potassium ion in the Kappa - Carrageenan rapaidly.
