A novel pomelo peel biochar/MgFe-layered double hydroxide composite (PPBC/MgFe-LDH) was synthesised using a facile coprecipitation approach and applied to remove cadmium ions (Cd (II)). The adsorption isotherm demonstrated that the Cd (II) by PPBC/MgFe-LDH fit Langmuir model well, behaviour monolayer chemisorption. maximum capacity of determined be 448.961 (±12.3) mg·g-1 from model, which close actual experimental 448.302 (±1.41) mg·g-1. results also chemical controlled rate reaction in process PPBC/MgFe-LDH. Piecewise fitting intra-particle diffusion revealed multi-linearity during process. Through associative characterization analysis, mechanism involved (i) formation or carbonate precipitation; (ii) an isomorphic substitution Fe (III) (II); (iii) surface complexation functional groups (-OH); (iv) electrostatic attraction. great potential for removing wastewater, with advantages synthesis excellent capacity.
