Outline of Final Research Achievements

The hybrid adsorbents of magnetite/cryogel were developed to apply the groundwater contaminated arsenic in Asia. The removal system of arsenic was investigated based on adsorption technique. Monolith and beads of the hybrid adsorbents prepared with ice as template under freezing were macroporous materials. The adsorption properties of arsenic using monolith and beads of the hybrid adsorbents were investigated by batchwise method. The column method was conducted to develop the removal process of arsenic using monolith of the hybrid adsorbents.
