摘要
为了有效解决聚酯纤维原料印染废水总锑超标问题,使其达标排放、减少环境污染,以微米和纳米羟基磷灰石(HAP)配合聚合硫酸铁(PFS)构建吸附材料,通过优化吸附水体中Sb(Ⅲ)工艺条件,研究不同组成吸附材料对Sb(Ⅲ)的吸附性能;借助ICP、zeta电位、BET、FESEM对吸附材料的电化学属性、表观及内部结构等进行分析与表征。结果表明:微米和纳米HAP、微米HAP+PFS、纳米HAP+PFS对水体中Sb(Ⅲ)吸附能力分别达到64.5%、74.9%、80.0%和97.5%,PFS中铁羟基可与Sb(Ⅲ)发生表面络合吸附,对于协助HAP吸附水体中Sb(Ⅲ)起到强化作用,可以考虑根据具体水质情况和处理要求,选择适宜HAP组合,应用于印染废水中Sb(Ⅲ)的吸附去除过程。
In order to solve the problem of total antimony emission in dyeing wastewater from polyester fiber production,micro-and nano-hydroxyapatite(HAP)as well as polymeric ferric sulfate(PFS)were employed to construct adsorption materials.The performance of the different adsorption materials for Sb(Ⅲ)removal were evaluated.Their electrochemical properties,apparent and internal structures were also characterized by ICP,zeta potential,BET and FESEM.The positive results showed that the adsorption capacities of micro-HAP,nano-HAP,micro-HAP+PFS and nano-HAP+PFS,reached 64.5%,74.9%,80.0%and 97.5%for the Sb(Ⅲ)in water respectively.The iron hydroxy groups in PFS could complex with Sb(Ⅲ).This could strengthen the HAP adsorption for Sb(Ⅲ)in water.The suitable HAP adsorption materials could be selected for the application in removing Sb(Ⅲ)from dyeing wastewaters according to the specific water quality and treatment requirements.
