Abstract

The invention discloses a preparation method of a mixed glycosyl compound with high adsorption performance, and relates to the technical field of compound preparation, the preparation method is characterized in that chitosan, glucose or chitosan and sucrose mixed sugar is used as a matrix, and polyether and sodium tripolyphosphate are added to prepare a compound adsorbent with high performance. The synthesis of the compound adsorbent mainly depends on the synergistic effect of coupling a large number of hydrogen bonds between mixed sugar and polyether with ionic bonds between chitosan and sodium tripolyphosphate. In the preparation process, the used raw materials and reagents have the characteristics of being safe, environment-friendly and non-toxic, the experimental step of high-temperature carbonization is omitted in the preparation process, and the high-performance compound adsorbent can be obtained without introducing shielding gas, so that the cost is fundamentally saved, the process preparation process is simplified, industrial production can be realized, and the method is suitable for industrial production. The problem of purification of the MO dye wastewater can be practically solved.
