【 摘 要 】

Sodium alginate aerogel prepared by vacuum freeze-dry method was first crossed bonding in organic solvent. Using 95 % ethanol as an organic solvent, the organic solution of calcium chloride has retained the original morphological structure of aerogel, which has better adsorption property. Then sodium ions were replaced by calcium ions through cross-linking reaction to gain the porous calcium alginate aerogel. After natural drying, product is completed. The experimental parameters such as the contact time, pH, temper and dosage prove the adsorption properties of methylene blue on the porous calcium alginate aerogel.
