Take removes in the water to have the slight pollutant as the goal activated charcoal surface modified direction is : the reduced surface lactone base and the carboxyl group and so on contain the oxygen functional group the content , increase activated charcoal surface sparse river characterthe modified activated charcoal in has a drink together in the water used adsorption treating processes , a weak basicity environment is good 我们研究了以浓硝酸、次氯酸和氨水去除水中三氯甲烷为主要目标表面改性活性炭吸附处理技术。立意方向为:减少表面内酯基及羧基等含氧官能团的含量,增加活性炭表面的疏水性。
