Adsorbents are a promising method for the removal of heavy metal contaminants. Herein, polyaspartic acid\/carboxymethyl poplar sawdust hydrogels (PASP\/CMPP) and ascorbic acid\/carboxymethyl poplar sawdust hydrogels (VC\/CMPP) were prepared by aqueous polymerization using alkalized poplar sawdust (CMPP) as the substrate and PASP and vitamin C (VC) as modifiers. The effective results, provided by the characterization analysis of SEM and BET, indicate that the surface of the PASP\/CMPP hydrogel has a larger number of loose pores and a larger pore volume than the VC\/CMPP hydrogel. The treatment effects of the two hydrogels on simulated wastewater containing Cd(II) were investigated by a batch of experiments. The results showed that PASP\/CMPP had a better adsorption effect than VC\/CMPP under the same adsorption conditions. Interestingly, the solid concentration effect was found in the process of sorption kinetics and sorption isotherms. The sorption kinetic curves of Cd(II) on PASP\/CMPP were well-fitted by the quasi-second-order kinetics under different adsorbent concentrations. The adsorption conforms to Langmuir and Freundlich adsorption isotherm models. More importantly, PASP\/CMPP composites are expected to be used as a new kind of environmental adsorbent for wastewater treatment.<\/jats:p>","DOI":"10.2166\/wh.2023.252","type":"journal-article","created":{"date-parts":[[2023,5,15]],"date-time":"2023-05-15T13:05:12Z","timestamp":1684155912000},"page":"676-686","update-policy":"https:\/\/doi.org\/10.2166\/iwapcrossmarkpolicypage","source":"Crossref","is-referenced-by-count":7,"title":["Preparation
