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/mL,碱提取工艺制备的海藻肥中甜菜碱含量最低为10.60 mg/mL.[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.
Abstract
[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.
