中文摘要
本研究主要是在探討吸附時間、吸附溫度、pH 值及離子濃
度對有機黏土吸附Acid Red 1 (AR1) 和Acid Blue 9 (AB9) 兩種酸性染
料之影響。研究結果顯示，有機黏土吸附AR1 和AB9 兩種酸性染料的
吸附曲線均屬H 型和放熱反應，另外，在較低溫，強酸、強鹼及高離
子濃度下吸附效果較好，而雙成分吸附則顯示其具有競爭吸附效應。最
後，由吸附動力學分析發現有機黏土對AR1 和AB9 的吸附反應為擬二
階反應且AB9 的吸附速率常數較AR1 大。
英文摘要
The effects of contact time, temperature, pH and ionic strength
on the adsorption of two acid dyes (Acid Red 1 (AR1) and Acid Blue 9
(AB9)) from aqueous solution onto organoclay were investigated. It was
found that the adsorption isotherms of all single dye systems belonged to H
type curve and adsorption process was exothermical. Low temperature,
strong acid and base and high ionic strength were favorable for the
adsorption of these dyes. Moreover, the competition effect was revealed
with the binary adsorption experiment. On the other hand, the adsorption
kinetics could be well described with the pseudo-second order rate
expression and the kinetic rate constant of AB9 is larger than that of AB1.
