摘要:
研究甲醛活化黑茶渣对水溶液中p-CNB的吸附性能,分别考察了甲醛浓度、吸附时间、吸附温度、pH、p-CNB初始浓度和吸附剂用量对黑茶渣吸附p-CNB的影响﹒结果表明:经10%甲醛处理后的黑茶渣对p-CNB的吸附性能较佳,在吸附时间为50 min、吸附温度为20 ℃、pH=7、p-CNB初始浓度为20 mg/L、吸附剂用量为0.6 g/50 mL时,p-CNB去除率达38.9%;与未处理黑茶渣样相比,10%甲醛活化黑茶渣对p-CNB有较好的吸附性能﹒
Abstract:
The adsorption performance of formaldehyde-activated dark tea residues on p-CNB in aqueous solution was studied. The effects of formaldehyde concentration, adsorption time, adsorption temperature, pH, initial concentration of the p-CNB and dosage of adsorbent on the adsorption of the p-CNB from dark tea residues were investigated. The results showed that the dark tea residues treated with 10% formaldehyde had better adsorption performance on the p-CNB, with adsorption time of 50 min, adsorption temperature of 20 ℃, pH=7, initial concentration of the p-CNB of 20 mg/L and the dosage of adsorbent is 0.6 g/50 mL, under this preferred adsorption condition, the p-CNB removal rate was 38.9%. Compared with the untreated dark tea residues, 10% formaldehyde activated dark tea residues had good adsorption performance for the p-CNB.
