Abstract

The invention discloses a method for producing sodium alginate by applying brown algae. The method is characterized by treating the brown algae by utilizing a fenton method to obtain a treatment product and extracting the sodium alginate from the treatment product, wherein the particular process of treating the brown algae by utilizing the fenton method comprises the following steps of soaking the brown algae in a ferrous ion solution, wherein the weight ratio of the brown algae and ferrous ions in the ferrous ion solution is (500:1)-(10:1); then adding a hydrogen peroxide solution to the ferrous ion solution, and treating for 1-100 minutes, wherein the amount of substance ratio of the ferrous ions and hydrogen peroxide in a mixed solution is not lower than 1:1. The method disclosed by the invention has the advantages of low energy consumption, convenient operation, low water consumption and fast degradation, is used for increasing the output of the sodium alginate produced by applying the brown algae and especially provides a simple, convenient and effective method for producing the low-viscosity sodium alginate.

Description

technical field [0001] The invention relates to the technical field of marine chemical industry, in particular to a method for producing sodium alginate by using brown algae. Background technique [0002] The research on seaweed polysaccharide has a long history. In 1670, the Japanese extracted agar from red algae. After the discovery of alginate by Stanford in 1881, production began in the United Kingdom, but it was not until 1929 in the United States that the large-scale production of alginate officially started in San Diego, using macroalgae produced on the local coast as raw materials. Thereafter, France, Norway and other countries also produced raw materials such as kelp and Ascophyllum nodosum. Since the 1950s, the use of alginate in the food industry, medicine, textile industry, etc. has become more and more extensive, which has promoted the development of the alginate industry to maintain a strong momentum. The countries that mainly produce alginate use the wild la...
