Coal ash as adsorbent for heavy metal ions in standard solutions, industrial wastewater and streams

One of the subjects of interest in the last years, is to develop new applications of fly ash, produced in growing quantities by burning coal in all coal-fired power stations. In this study, we have investigated the possible effects of Kosova lignite fly ash as adsorbent for removal of heavy metal ions in standard solutions, industrial wastewater and the natural water body (Sitnica river). Achieved results showed that 10 minutes of contact time, for standard solutions and natural water body, were appropriate for efficient adsorption of ions reaching the maximum removal to 99.89 wt% and 60 minutes of contact time for industrial wastewater, reaching the maximum removal of 98.12%.
