| Summary: | 碩士 === 國立高雄應用科技大學 === 化學工程與材料工程系博碩士班 === 101 === In the present study, the activated carbon modified (MAC) by nano-silver containning resin binder developed in our laboratory were successfully synthesized by impregnation process.
The characterizations of MAC such as the adsorbed amount of nano-silver resin , specific surface area , iodine value , residual chlorine , amount of nano- silver , dissolution of micro carbon powder , release of silver in water and antibacterial activity towards E. coli were discussed by changing concentration and impreganatioin time of nano-silver resin.
The experimental results showed that after impregnation with nano- silver resin , the MAC still maintained a high specific surface area , excellent adsorption capacity ( adsorption of micro carbon powder , iodine value and residual chlorine ) and antibacterial properties . The MAC with 10.1 % of silver resin can be prepared by impreganatioin in 5 wt % resin binder for 60 min. Durring the process of dissolution of micro carbon powder , the solution of MAC kept transparent.The silver release concentration of MAC below 0.05 ppm to fit in with the law of environmental protection, and also achieved excellent antibacterial effect (100 %).
