摘要
用分光光度法研究了天然沸石对甲基橙的吸附行为.较低的pH、较高的温度有利于吸附,3h吸附基本达到平衡,增加溶液中NaCl、CaCl2的浓度降低沸石对甲基橙的吸附量.随着平衡浓度增加,吸附量增大,且吸附符合Langmuir等温吸附方程,30℃时最大吸附量为7.06mg.g-1.
The behavior of adsorption methyl orange onto natrual zeolite was stydied by spectropotoscopy.Adsorption of methyl orange by zeolite strongly depends on pH, contact time, initial concentration of methyl orange, salt concentration, temperature and adsorbent dosage. The experimental data for single system at different temperatures fitted the Langmuir isotherm model excellently. The maximum adsorption capacity of methyl orange per gram zeolite was calculated from Langmiur isotherm as 7.06mg·g^-1 at 30℃.
