Interestingly, it is found that gPU and the hydrothermal process are the key factors for the assembly of the flowerlike structures of the Mg(OH)2, as its hexagonal nanosheet petals provide a high surface area. Temperature significantly controlled the morphologies of the flowerlike Mg(OH)(2), and the granular gPU-FMH showed the superb adsorption capacities of 472,1050, and 1293 mg g(-1) (maximum adsorption capacities, q(m), from Langmuir model) for Cu(II), Cd(II), and Pb(II), respectively. The proposed hypothesis for the synthesis of gPU-FMH and the removal mechanism of the heavy metals has been proved through various spectroscopic analyses. In the result of the continuous-flow column study, gPU-FMH showed a long breakthrough and a high removal capacity (184 mg g(-1)) of Cu(II). (C) 2018 Elsevier Ltd. All rights reserved.
