Abstract

The paper presents the study of Pb²⁺ lead ions sorption on multilayered graphene prepared by ultrasonic destruction of natural graphite in the presence of a surfactant. The concentration of Pb2+ ions in water was measured by spectrophotometric method using xylene orange indicator. It is shown that the sorption process does not have a threshold character at low concentrations of Pb²⁺ ions, and when their concentration goes up, the efﬁciency of sorption increases. The dynamics of sorption was studied; it was shown that the sorption of lead ions reaches its maximum sorption capacity value in 10 min. of sorption process.

Keywords: multilayer graphene, lead, sorption, xylene orange, water pollution
