以某制药公司制红霉素废渣为生物吸附材料,对模拟含Pb2+废水进行了吸附试验,并进行了吸附过程热力学分析。结果表明:氢氧化钠改性可明显提高制红霉素废渣的吸附能力;用经氢氧化钠改性的制红霉素废渣处理初始浓度为11.8 mg/L的模拟含Pb2+废水的适宜条件为室温、溶液pH=3.5、吸附时间15 min、废渣用量2g/L;Langmuir等温方程可以很好地描述制红霉素废渣对Pb2+的吸附行为。
Taking the erythromycin waste residue of a pharmaceutical company as bioadsorption material, the adsorption experiment of simulated Pb2 + -containing wastewater was carried out and the thermodynamic analysis of the adsorption process was carried out. The results showed that sodium hydroxide could improve the adsorption capacity of erythromycin waste residue. The optimum conditions for treating simulated Pb2 + wastewater containing 11.8 mg / L sodium hydroxide modified erythromycin waste were At room temperature, the solution pH = 3.5, adsorption time 15 min, the amount of waste residue 2g / L; Langmuir isotherm equation can well describe the adsorption of erythromycin waste residue Pb2 +.
