An amino-functionalised magnetic mesoporous silica was prepared through one-step copolymerisation method. Morphology, characteristic-group composition, microscopic morphology and specific surface area of the magnetic mesoporous silicas were analysed by scanning electron microscope, Fourier transform infrared spectroscopy, transmission electron microscope and nitrogen adsorption–desorption. The prepared magnetic silica MS-1 had the characteristics of micron-sized particle size, exceptional long-range ordered pore structure, and as high as 114.6 m2/g in specific surface area. The adsorption kinetics of tetracycline (TC) and Cu(II) onto magnetic mesoporous silicas in sole and binary system were also investigated. MS-1 could adsorb both of TC and Cu(II) with adsorption capacities of 35.14 and 23.65 mg/g, respectively, which were enhanced in binary systems about 26.5 and 19.7%, respectively. The solution pH significantly affected the adsorption because of the pH-responsive speciation of TC, TC–Cu(II) complex and the amine groups on adsorbent. This work proposed a potential effective method for the synergistic adsorption of antibiotics and heavy metals from aquatic environment.
