树脂吸附法回收母液中土霉素的实验研究

Experimental Study on Reclaiming Oxytetracycline in Fermentation Waste Liquor by Resin

研究了D061大孔强酸性阳离子交换树脂从土霉素生产母液中吸附土霉素的性能,并分析了相关影响因素。结果表明,该树脂对土霉素有良好的吸附性能,符合Langmuir吸附模型。在pH=2、钠型条件下,吸附容量高达122.4mg/g干树脂;用氨水脱附,脱附率可达95%;实验表明,母液中铵根的存在,对树脂交换容量有较大的影响。

This study dealt with D061 resin, a macroporous strong acidic resin, which was used to recover oxytetracycline from the fermentation residue mother liquor, focusing on its exchange properties in terms of static saturated adsorption volume, the desorption rate and the adverse influence of remaining ammonium in the waste liquor.
