砷暴露是一种全球性的健康危害，特别是在工业废水径流和高水平的天然含砷土壤的地区。目前的水过滤装置缺乏便携性，严重限制了它们在大规模公共卫生中的使用。在本研究中，骨炭，羟基磷灰石，针铁矿被纳入静电纺丝聚苯乙烯支架，以评估其砷的结合或吸附性能，在一个具有成本效益的，稳定的设备与便携性的潜力。使用电子显微镜证明了在研究中掺入所有掺杂剂的可行性。在污染的水中用单独的掺杂剂或掺杂剂掺入的电纺支架进行的砷测试表明，掺杂剂掺入的电纺支架与对照相比增加了砷结合，与仅掺杂剂的对应物相比有增加砷结合的趋势。结果表明，低成本，易于制造的静电纺丝聚苯乙烯是一个主要的选择，用于创建过滤材料浸渍与金属结合或吸附材料用于水过滤装置。(C)2016爱思唯尔有限公司版权所有。
Arsenic exposure is a global health hazard, particularly in areas with industrial wastewater runoff and high levels of naturally occurring arsenic-bearing soil. Current water filtration devices lack portability, severely limiting their use for wide-scale public health. In the present study, bone char, hydroxyapatite, and goethite were incorporated into electrospun polystyrene scaffolds to evaluate their arsenic binding or adsorption properties in a cost-effective, stable device with the potential for portability. Feasibility of incorporation for all dopants in the study was demonstrated using electron microscopy. Arsenic testing on contaminated water with either dopant alone or dopant-incorporated electrospun scaffolds demonstrated that the dopant-incorporated electrospun scaffolds increased arsenic binding over control, with a trend of increased arsenic binding over the dopant only counterparts. The results indicate that the low-cost, easily fabricated electrospun polystyrene is a prime choice for creating filter materials impregnated with metal binding or adsorbing materials for use in water filtration devices.
