摘要
采用实验室制备的含炔醇的碱液,探究活性炭吸附碱液中有机物的规律及吸附的最佳条件,并回收碱液中的钾离子得到优级纯硫酸钾产品.结果表明,活性炭吸附的最佳条件为:吸附温度为 40℃、活性炭用量为2 g/100 mL、pH为 5、吸附时间为 40 min;pH为5 时,溶液中的酯类有色物质会发生分解从而大幅度提高活性炭对有机物的去除率.
Abstract
Laboratory-prepared alkynol-containing alkali solution is taken to study the adsorption rule of organic components in alkali solution by activated carbon,and determine the optimal adsorption conditions.Potassium ions in alkali solution are recovered,and high-grade pure potassium sulfate product is obtained.Results show that the optimal conditions for activated carbon adsorption are as follows:adsorption temperature is 40℃,activated carbon dosage is 2 g per 100 mL,pH is 5,and adsorption time is 40 min.As pH is 5,ester colored substances in the solution will decompose,which greatly improves the removal rate of organic matters by activated carbon.
