Preparation of Adsorbent Based on Polyacrylate Latex Solid Waste and Its Application in the Treatment of Dye Wastewater.

ABSTRACT: It is a great challenge to sustainably produce and apply water-based coatings and inks in terms of realizing the green resource utilization of polyacrylate latex solid waste (PLSW) and avoid its secondary pollution. In this paper, a kind of high value-added amphoteric ion-exchange resin (AIER) was prepared by using diethylenetriamine to amidate PLSW under the optimized conditions from a Box-Behnken design. Its adsorption and regeneration properties and the universality of the method were investigated. The results suggested that AIER possessed a high removal efficiency to anionic dyes, and the batch dye adsorption processes were endothermic and spontaneous, which is consistent with a pseudo-second-order kinetic model. The penetration adsorption capacities of AIER were recorded to be 987.08
