摘要:為探究污泥基吸附劑材料對銅離子的去除效果，將市政污泥、山竹果皮廢棄物、四氧化三鐵和碳酸鉀按4∶1∶2.5∶0.5的質(zhì)量比相結(jié)合，在400 ℃條件下炭化1 h后制得高效磁性污泥基吸附劑，進一步化學(xué)改性后得到羧基化磁性污泥基吸附劑。將其用于含銅廢水的處理，并通過掃描電鏡等進行表征。結(jié)果表明，對于50 mL銅離子溶液（50 mg/L），溫度為25 ℃、pH為5.0、吸附劑投加量為25 mg是最優(yōu)吸附條件。準二級動力學(xué)模型和 Langmuir 吸附等溫線模型可以很好地描述吸附過程，對銅的最大吸附量為142.65 mg/g。同等條件下，相較于未改性前，羧基化改性磁性污泥基吸附劑的吸附容量提高約10%，平衡時間縮短約120 min。
Abstract:A high-efficiency sludge-based magnetic adsorbent was prepared under the following parameters: mass ratio of municipal sludge, mangosteen peel waste, ferric oxide and potassium carbonate of 4∶1∶2.5∶0.5, and carbonization at 400 ℃ for 1 h. After further chemical modification, a carboxylated sludge-based magnetic adsorbent was prepared for adsorption of copper-containing wastewater and characterized by scanning electron microscopy, so as to explore the performance of the sludge-based adsorbent materials for the removal of copper ions. For 50 mL of copper ion solution (50 mg/L), the optimal adsorption conditions were as follows: temperature of 25 ℃, pH of 5.0 and adsorbent dosage of 25 mg. The pseudo-second order kinetic and Langmuir isotherm model could fit the adsorption experiment well, and the maximum adsorption capacity was 142.65 mg/g. Under the same conditions, the adsorptive capacity of the modified carboxylated sludge-based magnetic adsorbent was increased by approximately 10% and the equilibrium time was shortened by approximately 120 min compared with those of the unmodified adsorbent.
