Adsorbent for adsorbing lead ions from aqueous solution and preparation method and adsorption method thereof

Abstract

The invention relates to the technical field of composite materials, in particular to an adsorbent for adsorbing lead ions from aqueous solution, and its preparation method and adsorption method. the adsorbent is prepared by a method including the steps of mixing raw materials, hot-pressing forming and calcining; in terms of weight percentage, the raw materials include the following components: 30-60 percent of polymer, 20-50 percent of diatomite, 12-30 percent of glass powder, 0.5-2 percent of compatibilizer and 2-5 percent of ferroferric oxide. the invention adopts glass powder to modify diatomite by melt blending and calcine to prepare the lead ion adsorbent; the lead ion adsorbent has high-efficiency adsorption performance and stable structure, may realize cyclic regeneration and utilization, and has broad application prospects in the field of lead ion-containing wastewater treatment.
