在處理染料廢水的方法中,利用吸附程序是有效的處理方法之ㄧ。利用廢棄物研製成吸附劑,可以降低處理成本。本研究以活性碳與廢污泥所研製的吸附劑,探討在不同溫度(30℃、40℃、45℃)及不同初始濃度(20~100ppm)的條件下,對於單獨存在與雙成分染料(RR141、AR27與MG)溶液的吸附行為進行研究,並探討其吸附平衡與動力之間的關係。此外也將TiO2與吸附劑結合,評估其吸附與降解染料的可行性。
結果研究顯示,以活性碳與自製吸附劑吸附雙成份染料MG+AR27與MG+RR141,吸附動力式皆以Pseudo-second-order equation的符合情形最佳。而活性碳的飽和吸附量略大於自製吸附劑,但是相差不大。單成份染料的等溫吸附模式,除了活性碳吸附RR141是以Freundlich adsorption isotherm來描述最佳,其餘皆是以Redlich-Peterson equation來描述最佳。將光觸媒吸附劑加入各種染料中得到的光降解效果並無明顯的差異。而光降解效果會因染料不同而不同。光降解雙成份染料實驗時,光降解效果會比單成份存在時的效果差。
Among various methods of wastewater treatment, adsorption is one of the effective processes. The objectives of the research is to compare the adsorption efficiencies of the commercial GAC and the adsorbents prepared from waste sludge, in terms of the removal of dyestuff solutions. Both single (RR141、AR27and MG) and binary mixed dyestuff solutions (MG+AR27 and MG+RR141) were studied , and effects of adsorption temperature (30℃、40℃、45℃) and initial concentration (20~100ppm) were also discussed. Besides, TiO2 and adsorbents were combined to evaluate the possibility of adsorption and photocatalytic degradation.
The results showed that the adsorption of binary mixed dye solutions using GAC and prepared adsorbents could be well described by the rate equation of pseudo-second-order reaction. The equilibrium adsorption capacity of GAC is slightly greater than that of prepared adsorbents. As for the adsorption isotherms, The Redlich-Peterson equation could successfully describe most conditions, except the adsorption of RR141 by GAC. There was no obvious difference among various photocatalytic reactions using different photocatalysts combined with adsorbents.
