Abstract:

采用氢气还原天然针铁矿和合成针铁矿制备铁粉,研究了反应时间、反应pH值、初始亚硝酸盐浓度等对两种还原铁粉去除亚硝酸盐的影响。结果表明反应3h、低亚硝酸盐初始浓度(<16mg/L)、低铁粉与亚硝酸盐质量比(<331)情况下,由合成针铁矿制备的还原铁粉对亚硝酸盐的去除率均高于由天然针铁矿制备出的铁粉,但随着反应时间的延长(>3h)、亚硝酸盐初始浓度的增加(>16mg/L)、铁粉与亚硝酸盐质量比的增加(>331),由天然针铁矿制备的还原铁粉对亚硝酸盐的去除率均高于由合成针铁矿制备出的铁粉。Al部分替代天然针铁矿中Fe阻碍了铁粉表面钝化膜的形成,从而增加了还原铁粉还原亚硝酸盐的稳定性,提高了亚硝酸盐的去除率。
