A CORE-SHELL COMPOSITION FOR PURIFYING CONTAMINATED WATER AND/OR BIOLOGICAL-MEDICAL SYSTEMS SUCH AS TISSUES, CELLS OR BLOOD

摘要

The invention relates to core-shell composition comprising a core of magnetic nanoparticles and a shell of a layered double hydroxide compound, and its procedure of obtainment. Furthermore, the invention refers to the use of said composition for purifying contaminated water, especially useful for the removal of harmful contaminants like arsenic, to make the water suitable for human consumption. Moreover, the invention refers to the use of said composition for purifying biological-medical systems such as tissues, cells or blood.
