本文对比研究了沸石、酸碱改性沸石、硅藻土、酸改性硅藻土、锰改性硅藻土、水葫芦干粉末、酸碱改性水葫芦干粉末、煤灰、煤渣、稻草秸秆粉末(＜40目)、稻草秸秆颗粒(粒径0.5cm)、玉米秸秆粉末(＜40目)、玉米秸秆颗粒(粒径0.5 em)、陶粒、铁氧化物改性陶粒等15种吸附材料吸附去除水体中Sb(Ⅴ)的效果.结果表明,在固液比为1 g:50 mL,初始溶液pH=7.5±0.5,反应温度为25±2℃,震荡速率150 r/min,初始Sb(Ⅴ)浓度为1 000 μg/L,吸附反应时间为5h条件下,15种吸附材料对Sb(Ⅴ)具有显著不同的吸附效果,吸附量大小依次为煤渣＞铁氧化物改性陶粒＞锰改性硅藻土＞酸碱改性水葫芦干粉末＞煤灰＞玉米秸秆粉末＞酸碱改性沸石＞酸改性硅藻土＞玉米秸秆颗粒＞稻草秸秆粉末＞沸石＞稻草秸秆颗粒＞陶粒＞水葫芦＞硅藻土.通过对原始吸附材料进行不同改性处理,发现改性后材料相对于原始材料对Sb(Ⅴ)的吸附能力有明显提升,其中锰改性硅藻土、酸碱改性水葫芦和铁氧化物改性陶粒对Sb(Ⅴ)的吸附量分别为48.7、46.6和48.9μg/g.其中,铁氧化物改性陶粒作为一种新型的大颗粒吸附剂,不仅对Sb(Ⅴ)的吸附性能好,而且相对于传统的粉末型吸附剂更易于从被处理水体中取出,避免了吸附剂和目标毒害元素驻留在水体中产生二次释放的环境风险,具有较好的应用潜力.“,”Fifteen groups of adsorption materials,including zeolite,acid and alkali modified zeolite,diatomite,acid modified diatomite,manganese modified diatomite,dry powder of water hyacinth,acid modified dry powder of water hyacinth,coal fly ash,coal cinder,rice straw powder(＜40 mesh),rice straw particles(diameter=0.5 cm),corn straw powder(＜40 mesh),corn straw particles(diameter=0.5 cm),ceramsite and iron oxide modified ceramsite were selected to investigate their adsorption capacities of Sb(Ⅴ) from simulated Sb-contaminated water at the present study.Results show that the applied adsorption materials have significantly different removal rates for Sb(Ⅴ),under the specific conditions of dosage of adsorbent(S/L) =1 g/50 mL,initial solution pH =7.5±0.5,reaction temperature of 25-±2 ℃,rotating speed of 150 rpm,initial concentration of Sb(Ⅴ) of 1 000 μg/L,and adsorption time of 5 h.However,the adsorptive capacities for Sb(Ⅴ)are significantly elevated,after the raw materials are chemically modified.For example,the Sb(Ⅴ) adsorption capacities of manganese modified diatomite,acid modified dry powder of water hyacinth and iron oxide modified ceramsite reach 48.7,46.6 and 48.9 μg/g,respectively.Particularly,this study figure out that iron oxide modified ceramsite is characterized by high adsorptive capacity for Sb(Ⅴ)and easy recycle in water,which highlights application potential for Sb(Ⅴ)cleanup in water,with advantages of high removal rate,easy recycle,and less secondary pollution risks.
