采用天然锰砂对水溶液中溴酚(BPs)的去除效果及其机理进行了研究,以2,4-二溴酚为代表,考察了天然锰砂粒径大小和反应温度对去除反应的影响。结果表明,天然锰砂对不同BPs的去除能力不同,表现为2,6-二溴酚>2,4-二溴酚>2,4,6-三溴酚>2-溴酚>4-溴酚,去除过程主要为脱溴和吸附的共同作用；小粒径和高反应温度都能够提高BPs的去除效果；天然锰砂氧化转化2,4-二溴酚的主要产物为2-溴代对苯二酚和4-溴酚。

The efficiency and mechanism of natural manganese sand removing bromophenols (BPs) in aqueous were studied. Taking 2,4-dibromophenol as the research object, the influence of particle size of natural manganese sand and reaction temperature on BPs removal were investigated. The results showed that, the removal efficiency of natural manganese sand on different BPs followed the order of 2,6-dibromophenol > 2,4-dibro-mophenol > 2,4,6-tribromophenol > 2-bromophenol > 4-bromophenol. It could be seen that, BPs removal was mainly resulted by debromination-adsorption combined action, and the efficiency could be improved with smaller particle size and higher temperature, the main detected products of the oxidation of 2,4-dibromophenol by natural manganese sand were 2-bromohydroquinone and 4-bromophenol.
