拉斐特学院的土木和环境工程项目目前正在进行中 开发一种低成本、可靠的切入点技术来去除地下水中的砷 饮用水的来源。该技术是一种由氢氧化铁组成的复合吸附剂 活性氧化铝铁；它被命名为“铁强化活性氧化铝”（IEAA）。这个 IEAA已被证明能成功地将砷去除到低于最大污染物水平的水平 （MCL）为美国环境保护局最近制定的十亿分之十（ppb） 美国环保局（USEPA）。本文的研究重点在于一个更好的解决方案 了解参与砷去除的IEAA的表面特征。包括表格，数字。

Lafayette College's Civil and Environmental Engineering Program is currently developing a low cost, reliable, point-of-entry technology to remove arsenic from groundwater sources of drinking water. The technology is a composite sorbent composed of iron hydroxide and activated alumina iron; it has been named, "iron-enhanced activated alumina" (IEAA). The IEAA has proven to successfully remove arsenic to levels below the maximum contaminant level (MCL) of 10 parts per billion (ppb) recently established by the United States Environmental Protection Agency (USEPA). The research presented in this paper focuses on a better understanding the surface characteristics of the IEAA involved in the removal of arsenic. Includes table, figures.
