以硝酸铁为原料，以NaOH溶液为沉淀剂，通过恒pH沉淀法在pH3～9范围内制得四种水合氧化铁(Fh)，通过XRD、表面零电荷时pH(pHPZC)测定、N2 吸附-脱附法对其表征，以甲基橙为模拟污染物比较了其吸附性能.结果表明，当甲基橙的初始浓度为30 mg·L-1时，在pH值5时制备的Fh(Fh5)对MO的吸附去除率为92.8％，明显优于Fh3(34.1％)、Fh7(67.4％)和Fh9(53.7

研究表明,天然样品中存在着汞同位素的质量分馏(MDF）和非质量分馏(MIF）,主要是奇数汞同位素非质量分馏.实验表明,无机汞光还原、甲基汞光降解和液态单质汞蒸发等会产生奇数汞同位素非质量分馏.这可能解释水生生物中明显的MIF的实际观测结果.但是,由于非常低的汞浓度和基质干扰,水体汞同位素研究还非常有限,其在环境汞循环中的应用也鲜于报导.
铊(Tl)是一种具有很大毒害作用的稀有金属元素,其毒性远远大于普通重金属Cu、Pb、Zn和Ni元素,铊可从环境中进入植物引起人体中毒,严重者可导致神经植物人甚至死亡.植物中的Tl,尤其是蔬菜,长期以来都不在我国环境监测范围内,而Tl的化合物通常不带有明显特征,因此,Tl在蔬菜中的污染较少引起关注.本研究对粤北某冶金厂下游区河流旁的菜地生长的荷兰豆、空心菜、莙荙菜、生菜、油麦菜、芥菜和葱七种常见食用
