Sep 01, 2015018332Magnetic ion exchange resins MIEX were first used for the removal of natural organic matter in 1995 . Since then magnetic particles modified with polymer , , carbon nanotubes etc., have been used commercially. This review focuses on the use of various magnetic adsorbents for the removal of pollutants from wastewater.
A magnetic carrier contains a resin-filled magnetic core particle and a resin covering layer provided on a surface of the resin-filled magnetic core particle. The resin-filled mag

magnetic polymeric microparticle support chelated with various divalent metal 2ions 2Ni2, Cu2, Co , Zn for affinity capture, purification and recovery of polyhistidine-tagged fusion proteins. Since different types of His-tagged proteins have varying affinities for a particular metal ion
Aug 15, 2008018332A combination of both MACS and FACS has also been applied for a purer cell isolation scheme. For example, to obtain highly purified hematopoietic stem cells HSCs for cancer therapy, CD34 cells were positively selected using magnetic beads followed by sorting using a fluorescence-activated high speed cell sorter. However, both these methods ...
