Outline of Final Research Achievements

We have developed a high gradient magnetic separation system (HGMS) utilizing a rice hull magnetic activated carbon (RH-MAC) and a magnetic zeolite (MZL) as magnetic adsorbents to remove various hazardous materials and to recover valuable resource from water environment. RH-MAC has a lot of mesopores and nano-size magnetite inside. It adsorbed humic acid as a persistent organic material effectively. Furthermore it adsorbed hazardous metals of Pb, As, Hg and Cd effectively. We developed the new magnetic wire filtering system rounded on a 0.5 T permanent magnet drum. Therefore 99.4% of RH-MAC in the 100 mg/L slurry was captured in the magnetic filter at a flow rate of 230 mL/min. MZL was synthesized by the coprecipitation process using fly ash, sodium hydroxide and ferric chloride solution. It absorbed ammonia nitorogen and Sr, Rb and Li ions for recovery resource, effectively The adsorbed materials were able to be easily released due to the ion exchange of Na+ in NaCl solution.
