| 内容記述 | The large quantity of Indonesian coal combustion products (CCPs) will likely increase drastically and potentially be a serious problem in the future. This research aims to measure the element content of coal and CCPs, to assess leaching behavior and investigate the concentration level of heavy metals in leachate through TCLP, to analyze the correlation between the element content of coal, CCPs, and leachate of CCPs. The resulting analysis of average element content on coal shows that the dominant element content was boron. Moreover, the distribution of heavy metals tended to enrich to be fly ash. The concentration level of heavy metals on fly ash and bottom ash leachates from all the power plants generally was much lower than the standard threshold. The significant level of concentration on fly ash and bottom ash was shown by boron. The concentration levels of heavy metals of coal ash leachates from two power plants were also much lower than the standard limit. The correlation between the element content of parent coal and CCPs pointed to no correlation between the variables. The element content of coal had no correlation to the concentration of CCPs leachate excluding nickel and chromium on bottom ash. Finally, it is recommended to assess other heavy metals concentration such as arsenic, mangan and selenium on CCPs leachate and further conduct a long-term study about the characteristics, leaching behavior of heavy metal leachate and, its effects on the environment. |
