【 摘 要 】

The adsorption process using cornstalk as adsorbent was used to remove the single metal ion such as copper ion and cadmium ion. The adsorption kinetics of each contaminant then used to predict the interaction type of metal ion on surface of corn stalk by calculating pseudo order 1stand 2nd. The identification type as chemically or physically interaction was predicted from the quality of r2by plotting the adsorption capacity (q) and time (t). The r2were 0.01 and 0.99 for pseudo order 1st and 2nd respectively for Fe (II). The r2were 0.26 and 0.999 for pseudo order 1st and 2nd respectively for Cu (II). The result of adsorption interaction of metal ion and surface function of corn stalk is chemical type. SEM/EDX confirmed the Cu2+presence on cornstalk surface.
