The adsorbent was characterized by scanning electron microscopy and Fourier transform infrared analysis, the hydrogel adsorbent had a typical three-dimensional network structure, and manganese oxides particles were dispersed into the channel and pores structure. The adsorption of Hg2+ in water was tested by using the adsorbent. The results show that the adsorption isotherms were fitted well with Langmuir model, and the maximum Hg2+ adsorption capacity was 0.654 mmol g\u22121 (131.2 mg g\u22121). The adsorption kinetics followed a pseudo-second-order equation, and the adsorption equilibrium can be reached in the first 120 min. The optimum pH of adsorption was determined to be 8.0. The desorption efficiency of 94% can be reached using 0.7 mol L\u22121 HCl as the regeneration agent. The results suggest that this material can be a promising adsorbent for Hg2+ removal in several industrial processes.<\/jats:p>","DOI":"10.2166\/wst.2017.150","type":"journal-article","created":{"date-parts":[[2017,4,11]],"date-time":"2017-04-11T00:10:57Z","timestamp":1491869457000},"page":"747-753","update-policy":"https:\/\/doi.org\/10.2166\/iwapcrossmarkpolicypage","source":"Crossref","is-referenced-by-count":10,"title":["Adsorption
