【摘要】:水體中重金屬污染物銻因?yàn)榫哂休^高的積累毒性和致癌性而受到研究者的廣泛關(guān)注。近年來由于世界范圍內(nèi)的銻污染問題日益嚴(yán)峻,因此急需發(fā)展經(jīng)濟(jì)高效的銻污染處理技術(shù)。納米Fe~0、Fe_3O_4以及FeMnO_x等鐵基復(fù)合材料憑借其吸附能力強(qiáng),易分離回收以及安全環(huán)保等特點(diǎn)而成為國內(nèi)外銻污染去除領(lǐng)域的研究熱點(diǎn)。本文總結(jié)了零價(jià)鐵和鐵氧化物復(fù)合材料以及鐵基雙金屬氧化物的制備、改性方法及其對水中污染物銻的去除,重點(diǎn)分析了不同鐵基復(fù)合材料對Sb(Ⅲ)和Sb(Ⅴ)的吸附機(jī)理,總結(jié)了溫度、p H、共存離子等外界環(huán)境對鐵基復(fù)合材料吸附性能的影響機(jī)制,優(yōu)選了最佳的吸附條件。最后介紹了現(xiàn)有銻污染去除研究中存在的主要問題,展望了鐵基復(fù)合材料處理水中銻污染物的重點(diǎn)發(fā)展方向。
[Abstract]:Because of its high accumulation toxicity and carcinogenicity, antimony, a heavy metal pollutant in water, has been widely concerned by researchers. In recent years, the problem of antimony pollution in the world is becoming more and more serious, so it is urgent to develop economical and efficient antimony pollution treatment technology. Iron matrix composites such as Fe _ 2O _ 4, Fe _ 3O _ 4 and FeMnO_x have become the research focus in the field of antimony pollution removal at home and abroad because of their strong adsorption ability, easy separation and recovery, and safety and environmental protection. In this paper, the preparation, modification and removal of SB (鈪,
