Sažetak
Manganese (Mn) occurs naturally in aquatic ecosystems, since is one of the most widespread elements in the Earth’s crust, although higher Mn concentrations originate from anthropogenic activities. Since elevated Mn concentrations in water cause a number of aesthetic and technical problems and are health concern, it is necessary to keep its level under control. In this paper, the removal of Mn from an aqueous solution containing ≈ 20 mg Mn/L was examined by a combination of several low-cost treatment methods: oxidation (aeration) with alkalinisation using milk of lime, filtration, and finally sorption on different easy available materials: natural zeolite and industrial food processing waste – olive, cherry and sour cherry pits. It was found that oxidation of Mn(II) must be performed at pH > 9.0, leading to the much lower residual Mn concentration and better overall removal efficiency. Among all tested sorbents, almost complete (> 99%) Mn removal was obtained for sodium form of natural zeolite, while pits showed satisfying removal up to ≈ 64%. Finding a useful purpose for such waste is highly desirable, contributing to better management of solid waste and more favourable water treatment.
