영문 초록

The purposes of this study examine characteristics of color removal using slag in dyeing wastewater, compare activated carbon with its efficiency, and inquire into recycling possibility as a substitute. Considering that slag contained in SiO₂, Fe₂O₃ and Al₂O₃ compositions, and coagulants were mainly used aluminate and f errate in color removal. It could be known that color removal of slag was increased to pH 4, but was hardly changed with advancing to alkaline. Color intended to be high removed with increasing of agitation speed, but to be almost slow after 150 rpm. As a result on the experiment of Freundlich adsorption isotherms, adsorption intensity(1/n) appeared to be slag>activated carbon and adsorption capacity(k) came out activated carbon>slag.
