这项工作的第一个目标是检查pH值和磷酸盐对环境的影响 砷在新沉淀的Fe（III）（hydr）氧化物上的吸附。第二，影响 研究了在去除水中砷时同时氧化铁和砷的氧化剂类型 研究为了达到目标，进行了台架和现场研究。砷处理 根据实验观察提出了建议。包括7个参考文献、图表。

The first objective of this work was to examine the effect of pH and phosphate on the adsorption of arsenic onto freshly precipitated Fe(III) (hydr)oxides. Secondly, the effect of oxidant type used to oxidize both iron and arsenic on the removal of arsenic from water was studied. Bench and field studies were used to meet the objectives. Arsenic treatment recommendations were made based on experimental observations. Includes 7 references, figures.
