Abstract: A preparation method of a graphene-based composite aerogel material for adsorbing heavy metal ions especially for a chelating agent/polymer/graphene composite aerogel material, includes: (1) preparing a chelating agent active solution; (2) preparing a GO/polymer mixed solution; (3) mixing the GO/polymer mixed solution with the chelating agent active solution to obtain the graphene-based composite aerogel material through a hydrothermal reaction. The polymer is used to enhance the mechanical strength of the aerogel and the chelating agent is used to improve the adsorption performance of the aerogel. The hydrothermal reaction is utilized to reduce graphene oxide to partially reduced graphene oxide, thereby forming a graphene-based aerogel. The composite aerogel has a high specific surface area and good mechanical strength. Moreover, active sites provided by the chelating agent and graphene further enhance the adsorption performance of the composite aerogel for metal ions.

Abstract: The present disclosure provides a method of accumulating order-goods, including: acquiring a collection order queue; acquiring a collection order from the collection order queue, assigning a first slide to the collection order, and sending goods in the collection order to the first slide in response to a presence of a first slide in an idle state, wherein the first slide only allows sending of goods in one collection order at one time; and activating a second slide in response to a predetermined condition being satisfied, wherein the second slide allows simultaneous sending of goods in a plurality of collection orders. The present disclosure further provides a system of accumulating order-goods, an electronic apparatus, a computer-readable storage medium, and a device of accumulating order-goods.
