This study investigated enzymatically treated red algae, gelidium amansii, microfibers as a biosorption material of heavy metals. The microfibers obtained after the enzyme reaction showed an excellent ability to uptake of heavy metals; the absorption efficiency was reversely proportional to the length of fibers. It was also found that pH of solutions affected the adsorption behaviors of heavy metals due to the increased charge density; the maximized adsorption of heavy metals was obtained at pH 9. Especially, the absorption activity of microfiber is maximized in cleansing foam. These results highlight that our algae microfibers could be utilized as an effective remover of heavy metals from contaminated air, thus providing practical applicability to detoxify the face. |
