Halloysite nanotube applications for heavy metals removal from wastewater

Abstract

Halloysite is a clay mineral that it is found in nature being a non-toxic material. Halloysites are used in different industrial fields having an important potential. In this paper we reviewed the properties and structural characteristics of halloysites and their applications in wastewater treatment. Halloysites showed good results for heavy metals removal process from wastewater. Researches has been carried out on removing from wastewater heavy metals, such as: Cu(II), Fe(III), Cr(VI), Pd(II), Pb(II), Ag(I), Co(II), Zn(II).
