ABSTRACT: A 1,1-Dimethylbiguanide-functionalized magnetic mesoporous silica material (called Fe3O4/mSiO2-Met), was synthesized and determining its efficiency in copper removal from aqueous solutions with the study the effect of pH, contact time, initial concentration of Cu (II) ions and adsorbent dosage in a batch system was investigated.

Removal of anionic dyes from aqueous solution by ...

the particles makes their separation complex and the nanoadsorbents could not be separated easily from aqueous solution by filtration or centrifugation. This problem can be solved using magnetic nanoadsorbents as they can be manipulated by an external magnetic field [16,28,29]. Coating magnetic particles with modi-

Ionically modified magnetic nanomaterials for arsenic and ...

A simple pH-triggered desorption and regeneration of the adsorbent is also presented. With adsorption capacities for arsenic (50.5 mg/g) and chromium (35.2 mg/g), coupled with facile magnetic separation, this nanoadsorbent can be an attractive material for the …

Magnetic techniques for the isolation and purification of ...

Nov 26, 2004· Magnetic separation procedures can be employed in several ways. Preparative isolation of the target protein or peptide is usually necessary if further detailed study is intended. In other cases, however, the magnetic separation can be directly followed (after elution with an appropriate buffer) with SDS electrophoresis.

Removal of Toxic Mercury (II) from Water Fe O ...

magnetic separation technology with adsorption process have been widely used in environmental purification (Pal and Alocilja, 2009; Rocher et al., 2008). In this study, Fe3O4/hydroxyapatite (HAP) composite as a novel nanoadsorbent was prepared to investigate its removal capability of toxic Hg2+ from aqueous solutions.
