Abstract: A preparation method and an application of a scallop shell extract efficient adsorbent are provided. The adsorbent employs waste scallop shells as a primary raw material, and converts the scallop shells into an extract with excellent adsorption performance by heating and multiple times of extraction with acetic acid. The prepared scallop shell extract is used as an efficient adsorbent to be applied to adsorption of aqueous solution dyes and shows good adsorption performance. The preparation method has a simple preparation process, realizes high-value utilization of the waste scallop shells, effectively lightens the environmental burden, reduces shell pollution and waste, has low cost and high renewable efficiency, and has good ecological benefit and economic value.
