摘要
以五大连池南饮泉重碳酸矿泉水为对象,通过活性炭改性、重金属吸附技术筛选降低矿泉水中镍和钡含量的方法,考察该方法下不同实验条件对两者去除率影响,以确定改性活性炭对镍、钡吸附的最佳条件。结果表明:硝酸改性可提高活性炭吸附镍、钡能力;通过硝酸改性以后,活性炭投入量和吸附时间对镍、钡去除率的影响显著(P<0.05);投入量45 g,吸附时间210 min,吸附温度10℃时,改性活性炭可将矿泉水中镍含量降低至4.22μg/L,去除率达93.49%;钡含量降低至60μg/L,去除率达78.02%。
Activated carbon was modified by acid,alkali and loaded ions.The methods to reduce the content of nickel and barium in bicarbonate mineral water from wudalianchi were screened,and the effects of different experimental conditions on the removal rate were investigated.Orthogonal experiment was designed to determine the best adsorption conditions.The results show that the adsorption capacity of activated carbon for nickel and barium can be improved by nitric acid solution.There was a significant effect on the removal rate by the amount of modified activated carbon and adsorption time.Under the conditions of 45 g input,210 min adsorption time and 10℃adsorption temperature,the nickel content can be reduced to 4.22μg/L,and the removal rate was 93.49%;The barium content can be reduced to 60μg/L,and the removal rate was 78.02%.
