| 摘 要： | 由海藻原料提取褐藻酸钠被视为离子交换过程,提取方法有直接提取法和间接提取法两种。所谓直接提取法只包括一步离子交换反应,即藻体中的钙、镁、锶等离子被钠离子直接取代。 Ca(Alg)_2+2Na~+→2NaAlg+Ca~(2+) 而间接提取法包括了酸的前处理和碱溶解两步离子交换过程。即: Ca(Alg)_2+2H~+→2HAlg+Ca~(2+)

STUDIES ON THE EFFECT OF DIL. ACID PRE-TREATMENT ON THE PROCESS AND QUALITY OF ALGIN FROM LAMINARIA JAPONICA |
| |
| Abstract: | A series of dil. acid (HC1) pre-treatments were carried out. The results obtained can be summarized as follows. 1. The process of dil. acid pre-treatment reduced markedly the viscosity yet increased the yield of algin. 2. When NaOH was used in extraction of Na-alginate, algae must be pretreated with dil, acid and soft water must be used for washing and extraction. |
