Size-controlled synthesis of uniform akaganeite nanorods and their encapsulation in alginate microbeads for arsenic removal†
Abstract
Uniform, size-controllable akaganeite nanorods were synthesized by hydrolysis of ferric ions in a two-phase system using sodium oleate as a surfactant. The akaganeite nanorods encapsulated in alginate microbeads showed quick, easy arsenic removal from highly contaminated water, indicating their potential for purification of groundwater in developing countries.
