摘要
[目的]测定不同提取工艺制备的海藻肥中甜菜碱含量。[方法]设计试验比较重量法和非水滴定法的准确度,并采用重量法测定了不同工艺制备的海藻肥中甜菜碱的含量。[结果]不同工艺制备的海藻肥中甜菜碱含量最高为18.76 mg/m L,碱提取工艺制备的海藻肥中甜菜碱含量最低为10.60 mg/m L。[结论]生物方法提取的海藻肥中甜菜碱活性成分损失少,而化学方法提取的海藻肥中甜菜碱活性成分损失大。
[ Objective ] The aim is to determine betaine content in seaweed fertilizers prepared by different extraction processes. [ Method ] The accuracy of gravimetric method and non-aqueous titration was compared by designed experiment. The content of betaine in seaweed fertilizers prepared by different process was determined by gravimetric method. [ Result] The betaine content of microbiological extracting seaweed fertilizers prepared by different extraction processes was the highest,which was 18.76 mg/mL, and betaine content in the alkali extracting seaweed fertilizers was the lowest,which was 10.60 mg/mL. [ Conclusion] The loss of betaine active ingredient in biological extracting seaweed fertilizers was less. while the loss of betaine active ingredient in chemical extracting seaweed fertilizers was more.
