摘要: Magnetite nanoparticles were synthesized in the presence of polysaccharides and tested for enhanced arsenate removal. The characterized with respect to sorption As(III) As(V) from water immobilization soil. Polysaccharide-modified magnetite offer a much higher As capacity compared that offered by their nonstabilized counterparts. polysaccharide-to-iron ratio can be altered yield various properties. One potential uses starch-bridged is remove spent ion exchange brine provide easy separation gravity. Stabilized are readily deliverable soils, particles would retained under normal groundwater conditions. nanoparticle amendment provides an environmentally friendly cost-effective way comply newly enforced maximum contaminant level 10 μg/L.
