摘要
Abstract
Different pre-treatment methods on the extraction of sodium alginate were studied and Glutaraldehyde was used as the optimal solution instead of formaldehyde.The results showed that 2％ (v/v) glutaraldehyde was superior to formaldehyde as treatment solution.The optimum conditions of extraction were obtained as follows: ultrasonic power 50w, microwave power 500w, extraction for 60s, solid to liquid ratio of 1: 20, extraction 2 times.Compared with other extraction methods, the ultrasonic - microwave synergistic extraction was a better method for sodium alginate extraction with less time and higher extraction rate.This is a better method for extracting sodium alginate.关键词
