  • 摘要: 为阐明天然有机物（NOM）在纳米颗粒（NPs）吸附重金属中的作用，研究了蛋白质（牛血清白蛋白，BSA）、碳水化合物（海藻酸钠，NaAlg）和腐殖酸（HA）对二氧化钛纳米颗粒（TNPs）和氧化铈纳米颗粒（CNPs）聚集沉降和吸附Cd2+和Pb2+的影响.结果表明，当Pb2+和Cd2+在20—120 mg·L-1范围内，HA和NaAlg显著促进了TNPs和CNPs对这些金属离子的吸附（P<0.05），而BSA对这些金属吸附的影响甚微.TNPs-HA和TNPs-NaAlg对Pb2+的吸附分别提高了14%—41%和16%—57%，对Cd2+的吸附分别提高了12%—112%和22%—143%.与CNPs相比，CNPs-HA和CNPs-NaAlg对Pb2+的吸附增加了21%—71%和23%—65%，对Cd2+的吸附增加了26%—45%和45%—91%.并且NPs和NPs-NOM对Pb2+和Cd2+的吸附符合Freundlich吸附模型.离子强度的增加抑制了NPs-HA/NaAlg和NPs对Pb2+和Cd2+的吸附，而pH的增加对NPs-HA/NaAlg和NPs吸附Pb2+和Cd2+起促进作用.
    Abstract: In order to elucidate the role of natural organic matters (NOM) in nanoparticles (NPs) adsorbing heavy metals, current work investigated effects of protein (bovine serum albumin, BSA), carbohydrate (sodium alginate, NaAlg), and humic acid (HA) on the aggregation and sedimentation of TiO2 NPs (TNPs) and CeO2 NPs (CNPs), and on the adsorption of Cd2+ and Pb2+ by TNPs and CNPs. In the range of 20—120 mg·L-1 of Pb2+ and Cd2+, BSA had little effect on the adsorption, whereas HA and NaAlg significantly accelerated these metals adsorption by TNPs and CNPs (P<0.05). In the presence of HA and NaAlg, the adsorption by TNPs increased 14%—41% and 16%—57% for Pb2+, and 12%—112% and 22%—143% for Cd2+, respectively. Compared with CNPs alone, HA and NaAlg increased 21%—71% and 23%—65% for Pb2+, and 26%—45% and 45%—91% for Cd2+, respectively. The adsorption of Pb2+ and Cd2+ by NPs and NPs-NOM was well fitted by Freundlich model. The increase in ionic strength inhibited the adsorption of Pb2+ and Cd2+ by NPs and NPs-HA/NaAlg, and the increase of pH increased the adsorption of Pb2+ and Cd2+ by NPs and NPs-HA/NaAlg.
