摘要
用光度法研究由部分水解的海藻酸钠合成的海藻酸铁（Ⅲ）配合物与抗坏血酸氧化还原反应的速度方程，分析海藻酸钠水解程度与海藻酸铁在反应中行为的关系；并依据实验结果和简单铁（Ⅲ）配合物与抗坏血酸的反应机理推测海藻酸铁与抗坏血酸的反应机理，推测海藻酸铁的可能结构。
From the kinetics experimental results by photometry,the rate equations of redox reac-tions between Fe(Ⅲ)-alginate complexes synthesized by partial hydrolysis of sodium-algi-nate and ascorbic acid are determined.The rate constants do not change much with the syn-thetic conditions of Fe(Ⅲ)-alginate complexes,The reaction mechanism may be similar tothat of simple Fe(Ⅲ)complexes,The possible structure of Fe(Ⅲ)-alginate complexes is in-ferred.
